 ### Discussing How To Use LAMMPS
 
 The LAMMPS mailing list is hosted at SourceForge. The mailing list began in 2005, and now includes tens of thousands of messages in thousands of threads. LAMMPS developers try to respond to posted questions in a timely manner, but there are no guarantees. Please consider that people live in different timezone and may not have time to answer e-mails outside of their work hours.
-You can post to list by sending your email to lammps-users at lists.sourceforge.net (no subscription required), but before posting, please read the [mailing list guidelines](http://lammps.sandia.gov/guidelines.html) to maximize your chances to receive a helpful response.

 Anyone can browse/search previous questions/answers in the archives. You do not have to subscribe to the list to post questions, receive answers (to your questions), or browse/search the archives. You **do** need to subscribe to the list if you want emails for **all** the posts (as individual messages or in digest form), or to answer questions yourself. Feel free to sign up and help us out! Answering questions from fellow LAMMPS users is a great way to pay back the community for providing you a useful tool for free, and to pass on the advice you have received yourself to others. It improves your karma and helps you understand your own research better.

 ### Reporting Bugs
 
-While developers writing code for LAMMPS are careful to test their code, LAMMPS is such a large and complex software, that it is impossible to test for all combinations of features under all normal and not so normal circumstances. Thus bugs do happen, and if you suspect, that you have encountered one, please try to document it and report it as an [Issue](https://github.com/lammps/lammps/issues) on the LAMMPS GitHub project web page. However, before reporting a bug, you need to check whether this is something that may have already been corrected. The [Latest Features and Bug Fixes in LAMMPS](http://lammps.sandia.gov/bug.html) web page lists all significant changes to LAMMPS over the years. It also tells you what the current latest development version of LAMMPS is, and you should test whether your issue still applies to that version.

Keep the headlines that are relevant to your reported potential bug and replace the descriptions with the information as suggested by the descriptions.
 You can also attach small text files (please add the file name extension `.txt` or it will be rejected), images, or small compressed text files (using gzip, do not use RAR or 7-ZIP or similar tools that are uncommon outside of Windows machines). In many cases, bugs are best illustrated by providing a small input deck (do **not** attach your entire production input, but remove everything that is not required to reproduce the issue, and scale down your system size, that the resulting calculation runs fast and can be run on small desktop quickly).

 We encourage users to submit new features or modifications for LAMMPS to the core developers so they can be added to the LAMMPS distribution. The preferred way to manage and coordinate this is by submitting a pull request at the LAMMPS project on GitHub. For any larger modifications or programming project, you are encouraged to contact the LAMMPS developers ahead of time, in order to discuss implementation strategies and coding guidelines, that will make it easier to integrate your contribution and result in less work for everybody involved. You are also encouraged to search through the list of open issues on GitHub and submit a new issue for a planned feature, so you would not duplicate the work of others (and possibly get scooped by them) or have your work duplicated by others.
 
-How quickly your contribution will be integrated depends largely on how much effort it will cause to integrate and test it, how much it requires changes to the core code base, and of how much interest it is to the larger LAMMPS community.

Please see below for a checklist of typical requirements. Once you have prepared everything, see [this tutorial](https://lammps.sandia.gov/doc/Howto_github.html)
  for instructions on how to submit your changes or new files through a GitHub pull request
 
 Here is a checklist of steps you need to follow to submit a single file or user package for our consideration. Following these steps will save both you and us time. See existing files in packages in the source directory for examples. If you are uncertain, please ask on the lammps-users mailing list.
 
 * All source files you provide must compile with the most current version of LAMMPS with multiple configurations. In particular you need to test compiling LAMMPS from scratch with `-DLAMMPS_BIGBIG` set in addition to the default `-DLAMMPS_SMALLBIG` setting. Your code will need to work correctly in serial and in parallel using MPI.
-* For consistency with the rest of LAMMPS and especially, if you want your contribution(s) to be added to main LAMMPS code or one of its standard packages, it needs to be written in a style compatible with other LAMMPS source files. This means: 2-character indentation per level, no tabs, no lines over 80 characters. I/O is done via the C-style stdio library, class header files should not import any system headers outside <stdio.h>, STL containers should be avoided in headers, and forward declarations used where possible or needed. All added code should be placed into the LAMMPS_NS namespace or a sub-namespace; global or static variables should be avoided, as they conflict with the modular nature of LAMMPS and the C++ class structure. Header files must not import namespaces with using. This all is so the developers can more easily understand, integrate, and maintain your contribution and reduce conflicts with other parts of LAMMPS. This basically means that the code accesses data structures, performs its operations, and is formatted similar to other LAMMPS source files, including the use of the error class for error and warning messages.

All added code should be placed into the LAMMPS_NS namespace or a sub-namespace; global or static variables should be avoided, as they conflict with the modular nature of LAMMPS and the C++ class structure. There MUST NOT be any "using namespace XXX;" statements in headers. In the implementation file (<name>.cpp) system includes should be placed in angular brackets (<>) and for c-library functions the C++ style header files should be included (<cstdio> instead of <stdio.h>, or <cstring> instead of <string.h>). This all is so the developers can more easily understand, integrate, and maintain your contribution and reduce conflicts with other parts of LAMMPS. This basically means that the code accesses data structures, performs its operations, and is formatted similar to other LAMMPS source files, including the use of the error class for error and warning messages.
+* Source, style name, and documentation file should follow the following naming convention: style names should be lowercase and words separated by a forward slash; for a new fix style 'foo/bar', the class should be named FixFooBar, the name of the source files should be 'fix_foo_bar.h' and 'fix_foo_bar.cpp' and the corresponding documentation should be in a file 'fix_foo_bar.txt'.
 * If you want your contribution to be added as a user-contributed feature, and it is a single file (actually a `<name>.cpp` and `<name>.h` file) it can be rapidly added to the USER-MISC directory. Include the one-line entry to add to the USER-MISC/README file in that directory, along with the 2 source files. You can do this multiple times if you wish to contribute several individual features.
 * If you want your contribution to be added as a user-contribution and it is several related features, it is probably best to make it a user package directory with a name like USER-FOO. In addition to your new files, the directory should contain a README text file. The README should contain your name and contact information and a brief description of what your new package does. If your files depend on other LAMMPS style files also being installed (e.g. because your file is a derived class from the other LAMMPS class), then an Install.sh file is also needed to check for those dependencies. See other README and Install.sh files in other USER directories as examples. Send us a tarball of this USER-FOO directory.
 * Your new source files need to have the LAMMPS copyright, GPL notice, and your name and email address at the top, like other user-contributed LAMMPS source files. They need to create a class that is inside the LAMMPS namespace. If the file is for one of the USER packages, including USER-MISC, then we are not as picky about the coding style (see above). I.e. the files do not need to be in the same stylistic format and syntax as other LAMMPS files, though that would be nice for developers as well as users who try to read your code.

 ### Pull Requests
 
-For submitting pull requests, there is a [detailed tutorial](http://lammps.sandia.gov/doc/Howto_github.html) in the LAMMPS manual. Thus only a brief breakdown of the steps is presented here. Please note, that the LAMMPS developers are still reviewing and trying to improve the process. If you are unsure about something, do not hesitate to post a question on the lammps-users mailing list or contact one fo the core LAMMPS developers.

Please note, that the LAMMPS developers are still reviewing and trying to improve the process. If you are unsure about something, do not hesitate to post a question on the lammps-users mailing list or contact one fo the core LAMMPS developers.
 Immediately after the submission, the LAMMPS continuing integration server at ci.lammps.org will download your submitted branch and perform a simple compilation test, i.e. will test whether your submitted code can be compiled under various conditions. It will also do a check on whether your included documentation translates cleanly. Whether these tests are successful or fail will be recorded. If a test fails, please inspect the corresponding output on the CI server and take the necessary steps, if needed, so that the code can compile cleanly again. The test will be re-run each the pull request is updated with a push to the remote branch on GitHub.
-Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission. If you are not yet registered as a LAMMPS collaborator, you will receive an invitation for that.
-You may also receive comments and suggestions on the overall submission or specific details. If permitted, additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
+Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission. If you are not yet registered as a LAMMPS collaborator, you will receive an invitation for that. As part of the assesment, the pull request will be categorized with labels. There are two special labels: `needs_work` (indicates that work from the submitter of the pull request is needed) and `work_in_progress` (indicates, that the assigned LAMMPS developer will make changes, if not done by the contributor who made the submit). 
+You may also receive comments and suggestions on the overall submission or specific details and on occasion specific requests for changes as part of the review. If permitted, also additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
 The LAMMPS developer may then decide to assign the pull request to another developer (e.g. when that developer is more knowledgeable about the submitted feature or enhancement or has written the modified code). It may also happen, that additional developers are requested to provide a review and approve the changes. For submissions, that may change the general behavior of LAMMPS, or where a possibility of unwanted side effects exists, additional tests may be requested by the assigned developer.
 If the assigned developer is satisfied and considers the submission ready for inclusion into LAMMPS, the pull request will receive approvals and be merged into the master branch by one of the core LAMMPS developers. After the pull request is merged, you may delete the feature branch used for the pull request in your personal LAMMPS fork.
 Since the learning curve for git is quite steep for efficiently managing remote repositories, local and remote branches, pull requests and more, do not hesitate to ask questions, if you are not sure about how to do certain steps that are asked of you. Even if the changes asked of you do not make sense to you, they may be important for the LAMMPS developers. Please also note, that these all are guidelines and nothing set in stone. So depending on the nature of the contribution, the workflow may be adjusted.

+# Outline of include file conventions in LAMMPS
+
+This purpose of this document is to provide a point of reference
+for LAMMPS developers and contributors as to what include files
+and definitions to put where into LAMMPS source.

+
+## Table of Contents
+
+  * [Motivation](#motivation)
+  * [Rules](#rules)
+  * [Tools](#tools)
+  * [Legacy Code](#legacy-code)
+
+## Motivation
+
+The conventions outlined in this document are supposed to help make
+maintenance of the LAMMPS software easier.  By trying to achieve
+consistency across files contributed by different developers, it will
+become easier for the code maintainers to modify and adjust files and,
+overall, the chance for errors or portability issues will be reduced.
+The rules employed are supposed to minimize naming conflicts and
+simplify dependencies between files and thus speed up compilation. They
+may, as well, make otherwise hidden dependencies visible.
+
+## Rules
+
+Below are the various rules that are applied.  Not all are enforced
+strictly and automatically.  If there are no significant side effects,
+exceptions may be possible for cases where a full compliance to the
+rules may require a large effort compared to the benefit.
+
+### Core Files Versus Package Files
+
+All rules listed below are most strictly observed for core LAMMPS files,
+which are the files that are not part of a package, and the files of the
+packages MOLECULE, MANYBODY, KSPACE, and RIGID.  On the other end of
+the spectrum are USER packages and legacy packages that predate these
+rules and thus may not be fully compliant.  Also, new contributions
+will be checked more closely, while existing code will be incrementally
+adapted to the rules as time and required effort permits.
+
+### System Versus Local Header Files
+
+All system- or library-provided include files are included with angular
+brackets (examples: `#include <cstring>` or `#include <mpi.h>`) while
+include files provided with LAMMPS are included with double quotes
+(examples: `#include "pointers.h"` or `#include "compute_temp.h"`).
+
+For headers declaring functions of the C-library, the corresponding
+C++ versions should be included (examples: `#include <cstdlib>` or
+`#include <cctypes>`).  However, these includes are limited to those defined
+in the C++98 standard.  Some files thus must use the older style until
+the minimum C++ standard requirement of LAMMPS is lifted to C++11 or
+even beyond (examples: `#include <stdint.h>` versus `#include <cstdint>`
+or `#include <inttypes.h>` versus `#include <cinttypes>`).
+
+### C++ Standard Compliance
+
+LAMMPS core files currently correspond to the C++98 standard. Files
+requiring C++11 or later are only permitted in (optional) packages
+and particularly packages that are not part of the list of commonly
+used packages such as MOLECULE, KSPACE, MANYBODY, or RIGID.
+
+Also, LAMMPS uses the C-style stdio library for I/O instead of iostreams.
+Since using both at the same time can cause problems, iostreams should
+be avoided where possible.
+
+### Lean Header Files
+
+Header files will typically contain the definition of a (single) class.
+These header files should have as few include statements as possible.
+This is particularly important for classes that implement a "style" and
+thus use a macro of the kind `SomeStyle(some/name,SomeName)`. These will
+all be included in the auto-generated `"some_style.h"` files which 
+results in a high potential for direct or indirect symbol name clashes.
+
+In the ideal case, the header would only include one file defining the
+parent class. That would typically be either `#include "pointers.h"` for
+the `Pointers` class, or a header of a class derived from it like
+`#include "pair.h"` for the `Pair` class and so on.  References to other
+classes inside the class should be make through pointers, for which forward
+declarations (inside the `LAMMPS_NS` or the new class' namespace) can
+be employed.  The full definition will then be included into the corresponding
+implementation file.  In the given example from above, the header file
+would be called `some_name.h` and the implementation `some_name.cpp` (all
+lower case with underscores, while the class itself would be in camel case
+and no underscores `SomeName`, and the style name with lower case names separated by
+a forward slash).
+
+### Implementation Files
+
+In the implementation files (typically, those would have the same base name
+as the corresponding header with a .cpp extension instead of .h) include
+statements should follow the "include what you use" principle.
+
+### Order of Include Statements
+
+Include files should be included in this order:
+* the header matching the implementation (`some_class.h` for file `some_class.cpp`)
+* mpi.h
+* system and library headers (anything that is using angular brackets; C-library headers first, then C++)
+* LAMMPS local headers (preferably in alphabetical order)
+
+### Special Cases and Exceptions
+
+#### pointers.h
+
+The `pointer.h` header file also includes `cstdio` and `lmptype.h`
+(and through it `stdint.h`, `intttypes.h`, cstdlib, and `climits`).
+This means any header including `pointers.h` can assume that `FILE`,
+`NULL`, `INT_MAX` are defined.
+
+## Tools
+
+The [Include What You Use tool](https://include-what-you-use.org/)
+can be used to provide supporting information about compliance with
+the rules listed here.  There are some limitations and the IWYU tool
+may give incorrect advice.  The tools is activated by setting the
+CMake variable `CMAKE_CXX_INCLUDE_WHAT_YOU_USE` variable to the
+path of the `include-what-you-use` command.  When activated, the
+tool will be run after each compilation and provide suggestions for
+which include files should be added or removed.
+
+## Legacy Code
+
+A lot of code predates the application of the rules in this document
+and the rules themselves are a moving target.  So there are going to be
+significant chunks of code that do not fully comply.  This applies
+for example to the USER-REAXC, or the USER-ATC package.  The LAMMPS
+developers are dedicated to make an effort to improve the compliance
+and welcome volunteers wanting to help with the process.

+.TP
+\fB\-h\fR or \fB\-help\fR
+Print a brief help summary and a list of settings and options compiled
+into this executable. It also explicitly lists all LAMMPS styles
+(atom_style, fix, compute, pair_style, bond_style, etc) available in
+the specific executable. This can tell you if the command you want to
+use was included via the appropriate package at compile time.
+LAMMPS will print the info and immediately exit if this switch is used.
+.TP
+\fB\-e\fR or \fB\-echo\fR
+Set the style of command echoing. The style can be
+.B none
+or
+.B screen
+or
+.B log
+or
+.B both.
+Depending on the style, each command read from the input script will
+be echoed to the screen and/or logfile. This can be useful to figure
+out which line of your script is causing an input error.
+The default value is
+.B log.
+.TP
+\fB\-i <input file>\fR or \fB\-in <input file>\fR
+Specify a file to use as an input script. If it is not specified,
+LAMMPS reads its script from standard input. This is a required
+switch when running LAMMPS in multi-partition mode.
+.TP
+\fB\-k on/off [keyword value]\fR or \fB\-kokkos on/off [keyword value]\fR
+Enable or disable general KOKKOS support, as provided by the KOKKOS
+package.  Even if LAMMPS is built with this package, this switch must
+be set to \fBon\fR to enable running with KOKKOS-enabled styles. More
+details on this switch and its optional keyword value pairs are discussed
+at: https://lammps.sandia.gov/doc/Run_options.html
+.TP
+\fB\-l <log file>\fR or \fB\-log <log file>\fR
+Specify a log file for LAMMPS to write status information to.
+The default value is "log.lammps". If the file name "none" is used,
+\fBLAMMPS\fR will not write a log file. In multi-partition mode only
+some high-level all-partition information is written to the "<log file>"
+file, the remainder is written in a per-partition file "<log file>.N"
+with "N" being the respective partition number, unless overridden
+by the \-plog flag (see below).
+.TP
+\fB\-m <number>\fR or \fB\-mpicolor <number>\fR
+If used, this must be the first command-line argument after the
+.B LAMMPS
+executable name. It is only used when
+.B LAMMPS
+is launched by an mpirun command which also launches one or more
+other executable(s) at the same time.
+.B LAMMPS
+and the other executable(s) perform an MPI_Comm_split(), each with
+their own different colors, to split the MPI_COMM_WORLD communicator
+for each executable to the subset of processors they are supposed to
+be actually running on. Currently, this is only used in
+.B LAMMPS
+to perform client/server messaging with another application.
+.B LAMMPS
+can act as either a client or server (or both).
+.TP
+\fB\-nc\fR or \fB\-nocite\fR
+Disable writing the "log.cite" file which is normally written to
+list references for specific cite-able features used during a
+.B LAMMPS
+run.
+.TP
+\fB\-pk <style> [options]\fR or \fB\-package <style> [options]\fR
+Invoke the \fBpackage\R command with <style> and optional arguments.
+The syntax is the same as if the command appeared in an input script.
+For example "-pk gpu 2" is the same as "package gpu 2" in the input
+script. The possible styles and options are discussed in the
+.B LAMMPS
+manual for the "package" command. This switch can be used multiple
+times, e.g. to set options for the USER-INTEL and USER-OMP packages
+when used together. Along with the "-sf" or "-suffix" switch, this
+is a convenient mechanism for invoking accelerator packages and their
+options without having to edit an input script.
+.TP
+\fB\-p\fR or \fB\-partition\fR
+Invoke
+.B LAMMPS
+in multi-partition mode. Without this,
+.B LAMMPS
+uses all P processors allocated via MPI to run a single simulation.
+If this switch is used, the P processors are split into separate
+partitions and each partition runs its own simulation. The arguments
+to the switch specify the number of processors in each partition.
+Arguments of the form "MxN" mean M partitions, each with N processors.
+Arguments of the form "N" mean a single partition with N processors.
+The sum of processors in all partitions must be equal P. Thus the
+command “-partition 8x2 4 5” has 10 partitions and runs on a total
+of 25 processors.  Running with multiple partitions is required for
+multi-replica simulations, where each replica runs on on one or more
+few processors.
+.TP
+\fB\-pl <basename>\fR or \fB\-plog <basename>\fR
+Specify the base name for the per-partition log files in multi-partition
+runs, where partition N writes log information to <basename>.N.
+If basename is set to "none", then no per-partition log files are created.
+This overrides the name specified in the \-log command-line option.
+.TP
+\fB\-ps <basename>\fR or \fB\-pscreen <basename>\fR
+Specify the base name for the per-partition screen files in multi-partition
+runs, where partition N writes screen output to <basename>.N.
+If basename is set to "none", then no per-partition screen files are created.
+The default value is "screen" or whatever is set by the \-screen flag.
+.TP
+\fB\-r2data <restart file> [remap] <data file>\fR or
+\fB\-restart2data <restart file> [remap] <data file>\fR
+Convert <restart file> previously written by
+.B LAMMPS
+into a data file and immediately exit. This option has replaced the
+external restart2data executable. Following <restart file>
+argument, the optional word "remap" may be used. This has the
+same effect like adding it to a "read_restart" command.
+The syntax following the <data file> name is identical to the
+arguments of the "write_data" command. See the
+.B LAMMPS
+manual for details on either of the two commands.
+.TP
+\fB\-r2dump <restart file> [remap] <dump file>\fR or
+\fB\-restart2dump <restart file> [remap] <dump file>\fR
+Convert <restart file> previously written by
+.B LAMMPS
+into a dump file and immediately exit. Following <restart file>
+argument, the optional word "remap" may be used. This has the
+same effect like adding it to a "read_restart" command.
+The syntax following the <dump file> name is identical to the
+arguments of the "dump" command. See the
+.B LAMMPS
+manual for details on either of the two commands.
+.TP
+\fB\-sc <file name>\fR or \fB\-screen <file name>\fR
+Specify a file for
+.B LAMMPS
+to write its screen information to. By default, this will be
+the standard output. If <file name> is "none", (most) screen
+output will be suppressed.  In multi-partition mode only
+some high-level all-partition information is written to the
+screen or "<file name>" file, the remainder is written in a
+per-partition file "screen.N" or "<file name>.N" 
+with "N" being the respective partition number, and unless
+overridden by the \-pscreen flag (see above).
+.TP
+\fB\-sf <suffix>\fR or \fB\-suffix <suffix>\fR
+Use variants of various styles in the input, if they exist. This is
+achieved by transparently trying to convert a style named <my/style>
+into <my/style/suffix> if that latter style exists, but otherwise
+fall back to the former. The most useful suffixes are  "gpu",
+"intel", "kk", "omp", "opt", or "hybrid". These refer to styles from
+optional packages that LAMMPS can be built with. The hybrid suffix is
+special, as it enables, having two suffixes tried (e.g. first "intel"
+and then "omp") and thus requires two arguments. Along with the
+"-package" command-line switch, this is a convenient mechanism for
+invoking styles from accelerator packages and setting their options
+without having to edit an input script.
+
+See https://lammps.sandia.gov/doc/Run_options.html for additional
+details and discussions on command-line options.
+
+.SH LAMMPS BASICS
+LAMMPS executes by reading commands from a input script (text file),
+one line at a time.  When the input script ends, LAMMPS exits.  Each
+command causes LAMMPS to take some action.  It may set or change an
+internal, read and parse a file, or run a simulation.  Most commands
+have default settings, which means you only need to use the command
+if you wish to change the default.
+
+The ordering of commands in an input script is usually not very important
+unless a command like "run" is encountered, which starts some calculation
+using the current internal state. Also, if a "pair_style" or "bond_style"
+other similar style command is issued that has a different name from what
+was previously active, it will replace the previous style and wipe out
+all corresponding "pair_coeff" or "bond_coeff" or equivalent settings.
+Some commands are only valid when they follow other commands.  For
+example you cannot set the temperature of a group of atoms until atoms
+have been defined and a group command is used to define which atoms
+belong to the group of a given name. Sometimes command B will use values
+that can be set by command A. This means command A must precede command
+B in the input to have the desired effect. Some commands must be issued
+.B before
+the simulation box is defined and others can only be issued
+.B after.
+Many input script errors are detected by
+.B LAMMPS
+and an ERROR or WARNING message is printed.  The documentation for
+each command lists restrictions on how the command can be used, and
+the chapter on errors in the
+.B LAMMPS
+manual gives some additional information about error messages, if possible.

+.SH DESCRIPTION
+.PP
+.B MSI2LMP
+is a tool bundled with LAMMPS to aide in the conversion of simulation
+inputs from Biovia's Materials Studio software for use with LAMMPS.
+It is a standalone program that generates a LAMMPS data file based on
+the information in an MS .car file (atom coordinates), an .mdf file
+(molecular topology and atom types) and an .frc (forcefield parameters)
+file.  The .car and .mdf files are specific to a molecular system while
+the .frc file is specific to a forcefield (variant).  The only coherency
+needed between .frc and .car/.mdf files are the atom types.

+styles and bond styles and so on are required in the LAMMPS input file.
+Class I or class 1 uses similar combination of functional forms as Amber
+and Charmm force field and support the force fields 
+.B cvff
+and
+.B clayff.
+Class II or class 2 corresponds to the more complex force fields
+.B COMPASS
+and
+.B pcff.
+Class O or class 0 finally is an experimental and incomplete extension
+and supports generating output for
+.B OPLS-AA
+.TP
+\fB\-f <ffname>\fR, \fB\-frc <ffname>\fR
+The \-c or \-frc option allows the selection of the force field parameter
+file
+.B<ffname>.frc.
+Valid names for <ffname> with this distribution are: cvff, clayff, cvff_aug,
+pcff, compass_published, cff91, and oplsaa. If the argument is a pathname,
+i.e. it starts with a '.' or a '/', then this absolute path is used to read
+the force field, otherwise
+.B msi2lmp
+will look in the folder pointed to by the environment variable
+$MSI2LMP_LIBRARY. If the variable is not set, then it will look in the current
+directory. The extension '.frc' is appended, if missing.
+Default is to look for the cvff.frc force field file.
+.TP
+\fB\-p <loglevel>\fR, \fB\-print <loglevel>\fR,
+Selects the amount of information messages about the progress of the
+conversion printed to the screen.
+.B <loglevel>
+can be a number from 0 (silent except for errors) to 3 (very detailed).
+.TP
+\fB\-i\fR, \fB\-ignore\fR,
+Ignore errors about missing parameters and use 0.0 for the respective
+force constants making these no-ops. Is correct to be used for a few
+molecules and settings, but often an indication, that either the atom
+type assignment have errors, or the force field file is missing entries.
+.TP
+\fB\-n\fR, \fB\-nocenter\fR,
+Do not center the box around the (geometrical) center of the atoms,
+but around the origin. Default is to recenter.
+.TP
+\fB\-o\fR, \fB\-oldstyle\fR,
+Write out a data file without style hint comments to be compatible
+with old LAMMPS versions. Default is to write out those comments.
+.TP
+\fB-s <x> <y> <z>\fR, \fB-shift <x> <y> <z>\fR,

+for use with GNU make or gmake, or a build environment generated by CMake
+(Unix Makefiles, Xcode, Visual Studio, KDevelop or more).  As an

+Basic build options
+===================
+
+The following topics are covered on this page, for building both with
+CMake and make:
+
+* :ref:`Serial vs parallel build <serial>`
+* :ref:`Choice of compiler and compile/link options <compile>`
+* :ref:`Build LAMMPS as an executable or a library <exe>`
+* :ref:`Build the LAMMPS documentation <doc>`
+* :ref:`Install LAMMPS after a build <install>`
+
+
+----------
+
+
+.. _serial:
+
+Serial vs parallel build
+-------------------------------------
+
+LAMMPS can be built to run in parallel using the ubiquitous `MPI (message-passing interface) <https://en.wikipedia.org/wiki/Message_Passing_Interface>`_
+library.  Or it can built to run on a single processor (serial)
+without MPI.  It can also be built with support for OpenMP threading
+(see more discussion below).
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D BUILD_MPI=value        # yes or no, default is yes if CMake finds MPI, else no
+   -D BUILD_OMP=value        # yes or no (default)
+   -D LAMMPS_MACHINE=name    # name = mpi, serial, mybox, titan, laptop, etc
+                             # no default value
+
+The executable created by CMake (after running make) is lmp\_name.  If
+the LAMMPS\_MACHINE variable is not specified, the executable is just
+lmp.  Using BUILD\_MPI=no will produce a serial executable.
+
+**Traditional make**\ :
+
+
+.. parsed-literal::
+
+   cd lammps/src
+   make mpi                # parallel build, produces lmp_mpi using Makefile.mpi
+   make serial             # serial build, produces lmp_serial using Makefile/serial
+   make mybox          # uses Makefile.mybox to produce lmp_mybox
+
+Serial build (see src/MAKE/Makefile.serial):
+
+
+.. parsed-literal::
+
+   MPI_INC =       -I../STUBS
+   MPI_PATH =      -L../STUBS
+   MPI_LIB =       -lmpi_stubs
+
+For a parallel build, if MPI is installed on your system in the usual
+place (e.g. under /usr/local), you do not need to specify the 3
+variables MPI\_INC, MPI\_PATH, MPI\_LIB.  The MPI wrapper on the compiler
+(e.g. mpicxx, mpiCC) knows where to find the needed include and
+library files.  Failing this, these 3 variables can be used to specify
+where the mpi.h file (MPI\_INC), and the MPI library files (MPI\_PATH)
+are found, and the name of the library files (MPI\_LIB).
+
+For a serial build, you need to specify the 3 variables, as shown
+above.
+
+For a serial LAMMPS build, use the dummy MPI library provided in
+src/STUBS.  You also need to build the STUBS library for your platform
+before making LAMMPS itself.  A "make serial" build does this for.
+Otherwise, type "make mpi-stubs" from the src directory, or "make"
+from the src/STUBS dir.  If the build fails, you will need to edit the
+STUBS/Makefile for your platform.
+
+The file STUBS/mpi.c provides a CPU timer function called MPI\_Wtime()
+that calls gettimeofday() .  If your system doesn't support
+gettimeofday() , you'll need to insert code to call another timer.
+Note that the ANSI-standard function clock() rolls over after an hour
+or so, and is therefore insufficient for timing long LAMMPS
+simulations.
+
+**CMake and make info**\ :
+
+If you are installing MPI yourself, we recommend MPICH2 from Argonne
+National Laboratory or OpenMPI.  MPICH can be downloaded from the
+`Argonne MPI site <http://www.mcs.anl.gov/research/projects/mpich2/>`_.
+OpenMPI can be downloaded from the `OpenMPI site <http://www.open-mpi.org>`_.  Other MPI packages should also work.
+If you are running on a large parallel machine, your system admins or
+the vendor should have already installed a version of MPI, which is
+likely to be faster than a self-installed MPICH or OpenMPI, so find
+out how to build and link with it.
+
+The majority of OpenMP (threading) support in LAMMPS is provided by
+the USER-OMP package; see the :doc:`Speed omp <Speed_omp>` doc page for
+details. The USER-INTEL package also provides OpenMP support (it is
+compatible with USER-OMP) and adds vectorization support when compiled
+with the Intel compilers on top of that. Also, the KOKKOS package can
+be compiled for using OpenMP threading.
+
+However, there are a few commands in LAMMPS that have native OpenMP
+support.  These are commands in the MPIIO, SNAP, USER-DIFFRACTION, and
+USER-DPD packages.  In addition some packages support OpenMP threading
+indirectly through the libraries they interface to: e.g. LATTE and
+USER-COLVARS.  See the :doc:`Packages details <Packages_details>` doc
+page for more info on these packages and the doc pages for their
+respective commands for OpenMP threading info.
+
+For CMake, if you use BUILD\_OMP=yes, you can use these packages and
+turn on their native OpenMP support and turn on their native OpenMP
+support at run time, by setting the OMP\_NUM\_THREADS environment
+variable before you launch LAMMPS.
+
+For building via conventional make, the CCFLAGS and LINKFLAGS
+variables in Makefile.machine need to include the compiler flag that
+enables OpenMP. For GNU compilers it is -fopenmp.  For (recent) Intel
+compilers it is -qopenmp.  If you are using a different compiler,
+please refer to its documentation.
+
+.. _default-none-issues:
+
+**OpenMP Compiler compatibility info**\ : 
+
+Some compilers do not fully support the 'default(none)' directive
+and others (e.g. GCC version 9 and beyond) may implement OpenMP 4.0
+semantics, which are incompatible with the OpenMP 3.1 directives used
+in LAMMPS (for maximal compatibility with compiler versions in use).
+In those case, all 'default(none)' directives (which aid in detecting
+incorrect and unwanted sharing) can be replaced with 'default(shared)'
+while dropping all 'shared()' directives. The script
+'src/USER-OMP/hack\_openmp\_for\_pgi\_gcc9.sh' can be used to automate
+this conversion.
+
+
+----------
+
+
+.. _compile:
+
+Choice of compiler and compile/link options
+---------------------------------------------------------
+
+The choice of compiler and compiler flags can be important for
+performance.  Vendor compilers can produce faster code than
+open-source compilers like GNU.  On boxes with Intel CPUs, we suggest
+trying the `Intel C++ compiler <intel_>`_.
+
+.. _intel: https://software.intel.com/en-us/intel-compilers
+
+
+
+On parallel clusters or supercomputers which use "modules" for their
+compile/link environments, you can often access different compilers by
+simply loading the appropriate module before building LAMMPS.
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D CMAKE_CXX_COMPILER=name            # name of C++ compiler
+   -D CMAKE_C_COMPILER=name              # name of C compiler
+   -D CMAKE_Fortran_COMPILER=name        # name of Fortran compiler
+
+   -D CMAKE_CXX_FLAGS=string             # flags to use with C++ compiler
+   -D CMAKE_C_FLAGS=string               # flags to use with C compiler
+   -D CMAKE_Fortran_FLAGS=string         # flags to use with Fortran compiler
+
+By default CMake will use a compiler it finds and it will add
+optimization flags appropriate to that compiler and any :doc:`accelerator packages <Speed_packages>` you have included in the build.
+
+You can tell CMake to look for a specific compiler with these variable
+settings.  Likewise you can specify the FLAGS variables if you want to
+experiment with alternate optimization flags.  You should specify all
+3 compilers, so that the small number of LAMMPS source files written
+in C or Fortran are built with a compiler consistent with the one used
+for all the C++ files:
+
+
+.. parsed-literal::
+
+   Building with GNU Compilers:
+   cmake ../cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_Fortran_COMPILER=gfortran
+   Building with Intel Compilers:
+   cmake ../cmake -DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc -DCMAKE_Fortran_COMPILER=ifort
+   Building with LLVM/Clang Compilers:
+   cmake ../cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_Fortran_COMPILER=flang
+
+.. note::
+
+   When the cmake command completes, it prints info to the screen
+   as to which compilers it is using, and what flags will be used in the
+   compilation.  Note that if the top-level compiler is mpicxx, it is
+   simply a wrapper on a real compiler.  The underlying compiler info is
+   what will be listed in the CMake output.  You should check to insure
+   you are using the compiler and optimization flags are the ones you
+   want.
+
+**Makefile.machine settings**\ :
+
+Parallel build (see src/MAKE/Makefile.mpi):
+
+
+.. parsed-literal::
+
+   CC =            mpicxx
+   CCFLAGS =       -g -O3
+   LINK =          mpicxx
+   LINKFLAGS =     -g -O
+
+Serial build (see src/MAKE/Makefile.serial):
+
+
+.. parsed-literal::
+
+   CC =            g++
+   CCFLAGS =       -g -O3
+   LINK =          g++
+   LINKFLAGS =     -g -O
+
+The "compiler/linker settings" section of a Makefile.machine lists
+compiler and linker settings for your C++ compiler, including
+optimization flags.  You should always use mpicxx or mpiCC for
+a parallel build, since these compiler wrappers will include
+a variety of settings appropriate for your MPI installation.
+
+.. note::
+
+   If you build LAMMPS with any :doc:`accelerator packages <Speed_packages>` included, they have specific
+   optimization flags that are either required or recommended for optimal
+   performance.  You need to include these in the CCFLAGS and LINKFLAGS
+   settings above.  For details, see the individual package doc pages
+   listed on the :doc:`Speed packages <Speed_packages>` doc page.  Or
+   examine these files in the src/MAKE/OPTIONS directory.  They
+   correspond to each of the 5 accelerator packages and their hardware
+   variants:
+
+
+.. parsed-literal::
+
+   Makefile.opt                   # OPT package
+   Makefile.omp                   # USER-OMP package
+   Makefile.intel_cpu             # USER-INTEL package for CPUs
+   Makefile.intel_coprocessor     # USER-INTEL package for KNLs
+   Makefile.gpu                   # GPU package
+   Makefile.kokkos_cuda_mpi       # KOKKOS package for GPUs
+   Makefile.kokkos_omp            # KOKKOS package for CPUs (OpenMP)
+   Makefile.kokkos_phi            # KOKKOS package for KNLs (OpenMP)
+
+
+----------
+
+
+.. _exe:
+
+Build LAMMPS as an executable or a library
+----------------------------------------------------
+
+LAMMPS can be built as either an executable or as a static or shared
+library.  The LAMMPS library can be called from another application or
+a scripting language.  See the :doc:`Howto couple <Howto_couple>` doc
+page for more info on coupling LAMMPS to other codes.  See the
+:doc:`Python <Python_head>` doc page for more info on wrapping and
+running LAMMPS from Python via its library interface.
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D BUILD_EXE=value           # yes (default) or no
+   -D BUILD_LIB=value           # yes or no (default)
+   -D BUILD_SHARED_LIBS=value   # yes or no (default)
+   -D LAMMPS_LIB_SUFFIX=name    # name = mpi, serial, mybox, titan, laptop, etc
+                                # no default value
+
+Setting BUILD\_EXE=no will not produce an executable.  Setting
+BUILD\_LIB=yes will produce a static library named liblammps.a.
+Setting both BUILD\_LIB=yes and BUILD\_SHARED\_LIBS=yes will produce a
+shared library named liblammps.so. If LAMMPS\_LIB\_SUFFIX is set the generated
+libraries will be named liblammps\_name.a or liblammps\_name.so instead.
+
+**Traditional make**\ :
+
+
+.. parsed-literal::
+
+   cd lammps/src
+   make machine               # build LAMMPS executable lmp_machine
+   make mode=lib machine      # build LAMMPS static lib liblammps_machine.a
+   make mode=shlib machine    # build LAMMPS shared lib liblammps_machine.so
+
+The two library builds also create generic soft links, named
+liblammps.a and liblammps.so, which point to the liblammps\_machine
+files.
+
+**CMake and make info**\ :
+
+Note that for a shared library to be usable by a calling program, all
+the auxiliary libraries it depends on must also exist as shared
+libraries.  This will be the case for libraries included with LAMMPS,
+such as the dummy MPI library in src/STUBS or any package libraries in
+the lib/packages directory, since they are always built as shared
+libraries using the -fPIC switch.  However, if a library like MPI or
+FFTW does not exist as a shared library, the shared library build will
+generate an error.  This means you will need to install a shared
+library version of the auxiliary library.  The build instructions for
+the library should tell you how to do this.
+
+As an example, here is how to build and install the `MPICH library <mpich_>`_, a popular open-source version of MPI, distributed by
+Argonne National Lab, as a shared library in the default
+/usr/local/lib location:
+
+.. _mpich: http://www-unix.mcs.anl.gov/mpi
+
+
+
+
+.. parsed-literal::
+
+   ./configure --enable-shared
+   make
+   make install
+
+You may need to use "sudo make install" in place of the last line if
+you do not have write privileges for /usr/local/lib.  The end result
+should be the file /usr/local/lib/libmpich.so.
+
+
+----------
+
+
+.. _doc:
+
+Build the LAMMPS documentation
+----------------------------------------
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D BUILD_DOC=value       # yes or no (default)
+
+This will create the HTML doc pages within the CMake build directory.
+The reason to do this is if you want to "install" LAMMPS on a system
+after the CMake build via "make install", and include the doc pages in
+the install.
+
+**Traditional make**\ :
+
+
+.. parsed-literal::
+
+   cd lammps/doc
+   make html       # html doc pages
+   make pdf        # single Manual.pdf file
+
+This will create a lammps/doc/html dir with the HTML doc pages so that
+you can browse them locally on your system.  Type "make" from the
+lammps/doc dir to see other options.
+
+.. note::
+
+   You can also download a tarball of the documentation for the
+   current LAMMPS version (HTML and PDF files), from the website
+   `download page <http://lammps.sandia.gov/download.html>`_.
+
+
+----------
+
+
+.. _tools:
+
+Build LAMMPS tools
+------------------------------
+
+Some tools described in :doc:`Auxiliary tools <Tools>` can be built directly
+using CMake or Make.
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D BUILD_TOOLS=value       # yes or no (default)
+
+The generated binaries will also become part of the LAMMPS installation (see below)
+
+**Traditional make**\ :
+
+
+.. parsed-literal::
+
+   cd lammps/tools
+   make all              # build all binaries of tools
+   make binary2txt       # build only binary2txt tool
+   make chain            # build only chain tool
+   make micelle2d        # build only micelle2d tool
+   make thermo_extract   # build only thermo_extract tool
+
+
+----------
+
+
+.. _install:
+
+Install LAMMPS after a build
+------------------------------------------
+
+After building LAMMPS, you may wish to copy the LAMMPS executable of
+library, along with other LAMMPS files (library header, doc files) to
+a globally visible place on your system, for others to access.  Note
+that you may need super-user privileges (e.g. sudo) if the directory
+you want to copy files to is protected.
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   cmake -D CMAKE_INSTALL_PREFIX=path [options ...] ../cmake
+   make                        # perform make after CMake command
+   make install                # perform the installation into prefix
+
+**Traditional make**\ :
+
+There is no "install" option in the src/Makefile for LAMMPS.  If you
+wish to do this you will need to first build LAMMPS, then manually
+copy the desired LAMMPS files to the appropriate system directories.

+Build LAMMPS with CMake
+=======================
+
+This page is a short summary of how to use CMake to build LAMMPS.
+Details on CMake variables that enable specific LAMMPS build options
+are given on the pages linked to from the :doc:`Build <Build>` doc page.
+
+Richard Berger (Temple U) has also written a `more comprehensive guide <https://github.com/lammps/lammps/blob/master/cmake/README.md>`_
+for how to use CMake to build LAMMPS.  If you are new to CMake it is a
+good place to start.
+
+
+----------
+
+
+Building LAMMPS with CMake is a two-step process.  First you use CMake
+to create a build environment in a new directory.  On Linux systems,
+this will be based on makefiles for use with make.  Then you use the
+make command to build LAMMPS, which uses the created
+Makefile(s). Example:
+
+
+.. parsed-literal::
+
+   cd lammps                        # change to the LAMMPS distribution directory
+   mkdir build; cd build            # create a new directory (folder) for build
+   cmake [options ...] ../cmake     # configuration with (command-line) cmake
+   make                             # compilation
+
+The cmake command will detect available features, enable selected
+packages and options, and will generate the build environment.  By default
+this build environment will be created for "Unix Makefiles" on most
+platforms and particularly on Linux.  However, alternate build tools
+(e.g. Ninja) and support files for Integrated Development Environments
+(IDE) like Eclipse, CodeBlocks, or Kate can be generated, too. This is
+selected via the "-G" command line flag. For the rest of the documentation
+we will assume that the build environment is generated for makefiles
+and thus the make command will be used to compile and link LAMMPS as
+indicated above, producing (by default) an executable called "lmp" and
+a library called "liblammps.a" in the "build" folder.  When generating
+a build environment for the "Ninja" build tool, the build command would
+be "ninja" instead of "make".
+
+If your machine has multiple CPU cores (most do these days), using a
+command like "make -jN" (with N being the number of available local
+CPU cores) can be much faster.  If you plan to do development on
+LAMMPS or need to re-compile LAMMPS repeatedly, installation of the
+ccache (= Compiler Cache) software may speed up repeated compilation
+even more.
+
+After compilation, you may optionally install the LAMMPS executable into
+your system with:
+
+
+.. parsed-literal::
+
+   make install    # optional, copy LAMMPS executable & library elsewhere
+
+This will install the lammps executable and library (if requested), some
+tools (if configured) and additional files like library API headers,
+manpages, potential and force field files. The location of the installation
+tree is set by the CMake variable "CMAKE\_INSTALL\_PREFIX" which defaults
+to ${HOME}/.local
+
+
+----------
+
+
+There are 3 variants of CMake: a command-line version (cmake), a text mode
+UI version (ccmake), and a graphical GUI version (cmake-GUI).  You can use
+any of them interchangeably to configure and create the LAMMPS build
+environment.  On Linux all the versions produce a Makefile as their
+output.  See more details on each below.
+
+You can specify a variety of options with any of the 3 versions, which
+affect how the build is performed and what is included in the LAMMPS
+executable.  Links to pages explaining all the options are listed on
+the :doc:`Build <Build>` doc page.
+
+You must perform the CMake build system generation and compilation in
+a new directory you create.  It can be anywhere on your local machine.
+In these Build pages we assume that you are building in a directory
+called "lammps/build".  You can perform separate builds independently
+with different options, so long as you perform each of them in a
+separate directory you create.  All the auxiliary files created by one
+build process (executable, object files, log files, etc) are stored in
+this directory or sub-directories within it that CMake creates.
+
+.. note::
+
+   To perform a CMake build, no packages can be installed or a
+   build been previously attempted in the LAMMPS src directory by using
+   "make" commands to :doc:`perform a conventional LAMMPS build <Build_make>`.  CMake detects if this is the case and
+   generates an error, telling you to type "make no-all purge" in the src
+   directory to un-install all packages.  The purge removes all the \*.h
+   files auto-generated by make.
+
+You must have CMake version 2.8 or later on your system to build
+LAMMPS.  A handful of LAMMPS packages (KOKKOS, LATTE, MSCG) require a
+later version.  CMake will print a message telling you if a later
+version is required.  Installation instructions for CMake are below.
+
+After the initial build, if you edit LAMMPS source files, or add your
+own new files to the source directory, you can just re-type make from
+your build directory and it will re-compile only the files that have
+changed.  If you want to change CMake options you can run cmake (or
+ccmake or cmake-gui) again from the same build directory and alter
+various options; see details below.  Or you can remove the entire build
+folder, recreate the directory and start over.
+
+
+----------
+
+
+**Command-line version of CMake**\ :
+
+
+.. parsed-literal::
+
+   cmake [options ...] /path/to/lammps/cmake  # build from any dir
+   cmake [options ...] ../cmake               # build from lammps/build
+
+The cmake command takes one required argument, which is the LAMMPS
+cmake directory which contains the CMakeLists.txt file.
+
+The argument can be preceeded or followed by various CMake
+command-line options.  Several useful ones are:
+
+
+.. parsed-literal::
+
+   -D CMAKE_INSTALL_PREFIX=path  # where to install LAMMPS executable/lib if desired
+   -D CMAKE_BUILD_TYPE=type      # type = RelWithDebInfo (default), Release, MinSizeRel, or Debug
+   -G output                     # style of output CMake generates
+   -DVARIABLE=value              # setting for a LAMMPS feature to enable
+   -D VARIABLE=value             # ditto, but cannot come after CMakeLists.txt dir
+   -C path/to/preset/file        # load some CMake settings before configuring
+
+All the LAMMPS-specific -D variables that a LAMMPS build supports are
+described on the pages linked to from the :doc:`Build <Build>` doc page.
+All of these variable names are upper-case and their values are
+lower-case, e.g. -D LAMMPS\_SIZES=smallbig.  For boolean values, any of
+these forms can be used: yes/no, on/off, 1/0.
+
+On Unix/Linux machines, CMake generates a Makefile by default to
+perform the LAMMPS build.  Alternate forms of build info can be
+generated via the -G switch, e.g. Visual Studio on a Windows machine,
+Xcode on MacOS, or KDevelop on Linux.  Type "cmake --help" to see the
+"Generator" styles of output your system supports.
+
+.. note::
+
+   When CMake runs, it prints configuration info to the screen.
+   You should review this to verify all the features you requested were
+   enabled, including packages.  You can also see what compilers and
+   compile options will be used for the build.  Any errors in CMake
+   variable syntax will also be flagged, e.g. mis-typed variable names or
+   variable values.
+
+CMake creates a CMakeCache.txt file when it runs.  This stores all the
+settings, so that when running CMake again you can use the current
+folder '.' instead of the path to the LAMMPS cmake folder as the
+required argument to the CMake command. Either way the existing
+settings will be inherited unless the CMakeCache.txt file is removed.
+
+If you later want to change a setting you can rerun cmake in the build
+directory with different setting. Please note that some automatically
+detected variables will not change their value when you rerun cmake.
+In these cases it is usually better to first remove all the
+files/directories in the build directory, or start with a fresh build
+directory.
+
+
+----------
+
+
+**Curses version (terminal-style menu) of CMake**\ :
+
+
+.. parsed-literal::
+
+   ccmake ../cmake
+
+You initiate the configuration and build environment generation steps
+separately. For the first you have to type **c**\ , for the second you
+have to type **g**\ . You may need to type **c** multiple times, and may be
+required to edit some of the entries of CMake configuration variables
+in between.  Please see the `ccmake manual <https://cmake.org/cmake/help/latest/manual/ccmake.1.html>`_ for
+more information.
+
+
+----------
+
+
+**GUI version of CMake**\ :
+
+
+.. parsed-literal::
+
+   cmake-gui ../cmake
+
+You initiate the configuration and build environment generation steps
+separately. For the first you have to click on the **Configure** button,
+for the second you have to click on the **Generate** button.  You may
+need to click on **Configure** multiple times, and may be required to
+edit some of the entries of CMake configuration variables in between.
+Please see the `cmake-gui manual <https://cmake.org/cmake/help/latest/manual/cmake-gui.1.html>`_
+for more information.
+
+
+----------
+
+
+**Installing CMake**
+
+Check if your machine already has CMake installed:
+
+
+.. parsed-literal::
+
+   which cmake             # do you have it?
+   which cmake3            # version 3 may have this name
+   cmake --version         # what specific version you have
+
+On clusters or supercomputers which use environment modules to manage
+software packages, do this:
+
+
+.. parsed-literal::
+
+   module list            # is a cmake module already loaded?
+   module avail           # is a cmake module available?
+   module load cmake3     # load cmake module with appropriate name
+
+Most Linux distributions offer pre-compiled cmake packages through
+their package management system. If you do not have CMake or a new
+enough version, you can download the latest version at
+`https://cmake.org/download/ <https://cmake.org/download/>`_.
+Instructions on how to install it on various platforms can be found
+`on this page <https://cmake.org/install/>`_.

+Development build options (CMake only)
+======================================
+
+The CMake build of LAMMPS has a few extra options which are useful during
+development,  testing or debugging.
+
+
+----------
+
+
+.. _compilation:
+
+Verify compilation flags
+------------------------------------------
+
+Sometimes it is necessary to verify the complete sequence of compilation flags
+generated by the CMake build. To enable a more verbose output during
+compilation you can use the following option.
+
+
+.. parsed-literal::
+
+   -D CMAKE_VERBOSE_MAKEFILE=value    # value = no (default) or yes
+
+Another way of doing this without reconfiguration is calling make with variable VERBOSE set to 1:
+
+
+.. parsed-literal::
+
+   make VERBOSE=1
+
+
+----------
+
+
+.. _sanitizer:
+
+Address, Undefined Behavior, and Thread Sanitizer Support
+-------------------------------------------------------------------------
+
+Compilers such as GCC and Clang support generating binaries which use different
+sanitizers to detect problems in code during run-time. They can detect `memory leaks <https://clang.llvm.org/docs/AddressSanitizer.html>`_,
+code that runs into `undefined behavior <https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html>`_ of the
+language and `data races <https://clang.llvm.org/docs/ThreadSanitizer.html>`_ in threaded code.
+
+The following settings allow you enable these features if your compiler supports
+it. Please note that they come with a performance hit. However, they are
+usually faster than using tools like Valgrind.
+
+
+.. parsed-literal::
+
+   -D ENABLE_SANITIZE_ADDRESS=value    # enable Address Sanitizer, value = no (default) or yes
+   -D ENABLE_SANITIZE_UNDEFINED=value  # enable Undefined Behaviour Sanitizer, value = no (default) or yes
+   -D ENABLE_SANITIZE_THREAD=value     # enable Thread Sanitizer, value = no (default) or yes
+
+
+----------
+
+
+.. _testing:
+
+Code Coverage and Testing
+---------------------------------------
+
+We do extensive regression testing of the LAMMPS code base on a continuous
+basis. Some of the logic to do this has been added to the CMake build so
+developers can run the tests directly on their workstation.
+
+.. note::
+
+   this is incomplete and only represents a small subset of tests that we run
+
+
+.. parsed-literal::
+
+   -D ENABLE_TESTING=value               # enable simple run tests of LAMMPS, value = no (default) or yes
+   -D LAMMPS_TESTING_SOURCE_DIR=path     # path to lammps-testing repository (option if in custom location)
+   -D LAMMPS_TESTING_GIT_TAG=value       # version of lammps-testing repository that should be used, value = master (default) or custom git commit or tag
+
+If you enable testing in the CMake build it will create an additional target called "test". You can run them with:
+
+
+.. parsed-literal::
+
+   make test
+
+The test cases used come from the lammps-testing repository. They are
+derivatives of the examples folder with some modifications to make the run
+faster.
+
+You can also collect code coverage metrics while running the tests by enabling
+coverage support during building.
+
+
+.. parsed-literal::
+
+   -D ENABLE_COVERAGE=value  # enable coverage measurements, value = no (default) or yes
+
+This will also add the following targets to generate coverage reports after running the LAMMPS executable:
+
+
+.. parsed-literal::
+
+   make test               # run tests first!
+   make gen_coverage_html  # generate coverage report in HTML format
+   make gen_coverage_xml   # generate coverage report in XML format
+
+These reports require GCOVR to be installed. The easiest way to do this to install it via pip:
+
+
+.. parsed-literal::
+
+   pip install git+https://github.com/gcovr/gcovr.git

+Link LAMMPS as a library to another code
+========================================
+
+LAMMPS can be used as a library by another application, including
+Python scripts.  The files src/library.cpp and library.h define the
+C-style API for using LAMMPS as a library.  See the :doc:`Howto library <Howto_library>` doc page for a description of the
+interface and how to extend it for your needs.
+
+The :doc:`Build basics <Build_basics>` doc page explains how to build
+LAMMPS as either a shared or static library.  This results in one of
+these 2 files:
+
+liblammps.so      # shared library
+liblammps.a       # static library
+
+
+----------
+
+
+**Link with LAMMPS as a static library**\ :
+
+The calling application can link to LAMMPS as a static library with a
+link command like this:
+
+g++ caller.o -L/home/sjplimp/lammps/src -llammps -o caller
+
+The -L argument is the path to where the liblammps.a file is.  The
+-llammps argument is shorthand for the file liblammps.a.
+
+
+----------
+
+
+**Link with LAMMPS as a shared library**\ :
+
+If you wish to link to liblammps.so, the operating system finds shared
+libraries to load at run-time using the environment variable
+LD\_LIBRARY\_PATH.  To enable this you can do one of two things:
+
+(1) Copy the liblammps.so file to a location the system can find it,
+such as /usr/local/lib.  I.e. a directory already listed in your
+LD\_LIBRARY\_PATH variable.  You can type
+
+
+.. parsed-literal::
+
+   printenv LD_LIBRARY_PATH
+
+to see what directories are in that list.
+
+(2) Add the LAMMPS src directory (or the directory you perform CMake
+build in) to your LD\_LIBRARY\_PATH, so that the current version of the
+shared library is always available to programs that use it.
+
+For the csh or tcsh shells, you would add something like this to your
+~/.cshrc file:
+
+
+.. parsed-literal::
+
+   setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/home/sjplimp/lammps/src
+
+
+----------
+
+
+**Calling the LAMMPS library**\ :
+
+Either flavor of library (static or shared) allows one or more LAMMPS
+objects to be instantiated from the calling program.
+
+When used from a C++ program, all of LAMMPS is wrapped in a LAMMPS\_NS
+namespace; you can safely use any of its classes and methods from
+within the calling code, as needed.
+
+When used from a C or Fortran program, the library has a simple
+C-style interface, provided in src/library.cpp and src/library.h.
+
+See the :doc:`Python library <Python_library>` doc page for a
+description of the Python interface to LAMMPS, which wraps the C-style
+interface.
+
+See the sample codes in examples/COUPLE/simple for examples of C++ and
+C and Fortran codes that invoke LAMMPS through its library interface.
+Other examples in the COUPLE directory use coupling ideas discussed on
+the :doc:`Howto couple <Howto_couple>` doc page.

+Build LAMMPS with make
+======================
+
+Building LAMMPS with traditional makefiles requires that you have a
+Makefile."machine" file appropriate for your system in the src/MAKE,
+src/MAKE/MACHINES, src/MAKE/OPTIONS, or src/MAKE/MINE directory (see
+below).  It can include various options for customizing your LAMMPS
+build with a number of global compilation options and features.
+
+To include LAMMPS packages (i.e. optional commands and styles) you
+must install them first, as discussed on the :doc:`Build package <Build_package>` doc page.  If the packages require
+provided or external libraries, you must build those libraries before
+building LAMMPS.  Building :doc:`LAMMPS with CMake <Build_cmake>` can
+automate all of this for many types of machines, especially
+workstations, desktops and laptops, so we suggest you try it first.
+
+These commands perform a default LAMMPS build, producing the LAMMPS
+executable lmp\_serial or lmp\_mpi in lammps/src:
+
+
+.. parsed-literal::
+
+   cd lammps/src
+   make serial     # build a serial LAMMPS executable
+   make mpi        # build a parallel LAMMPS executable with MPI
+   make            # see a variety of make options
+
+This initial compilation can take a long time, since LAMMPS is a large
+project with many features. If your machine has multiple CPU cores
+(most do these days), using a command like "make -jN mpi" (with N =
+the number of available CPU cores) can be much faster.  If you plan to
+do development on LAMMPS or need to re-compile LAMMPS repeatedly, the
+installation of the ccache (= Compiler Cache) software may speed up
+compilation even more.
+
+After the initial build, whenever you edit LAMMPS source files, or add
+or remove new files to the source directory (e.g. by installing or
+uninstalling packages), you must re-compile and relink the LAMMPS
+executable with the same "make" command.  This makefiles dependencies
+should insure that only the subset of files that need to be are
+re-compiled.
+
+.. note::
+
+   When you build LAMMPS for the first time, a long list of \*.d
+   files will be printed out rapidly.  This is not an error; it is the
+   Makefile doing its normal creation of dependencies.
+
+
+----------
+
+
+The lammps/src/MAKE tree contains all the Makefile.machine files
+included in the LAMMPS distribution.  Typing "make machine" uses
+Makefile.machine.  Thus the "make serial" or "make mpi" lines above
+use Makefile.serial and Makefile.mpi.  Others are in these dirs:
+
+
+.. parsed-literal::
+
+   OPTIONS      # Makefiles which enable specific options
+   MACHINES     # Makefiles for specific machines
+   MINE         # customized Makefiles you create (you may need to create this folder)
+
+Typing "make" lists all the available Makefile.machine files.  A file
+with the same name can appear in multiple folders (not a good idea).
+The order the dirs are searched is as follows: src/MAKE/MINE,
+src/MAKE, src/MAKE/OPTIONS, src/MAKE/MACHINES.  This gives preference
+to a customized file you put in src/MAKE/MINE.
+
+Makefiles you may wish to try include these (some require a package
+first be installed).  Many of these include specific compiler flags
+for optimized performance.  Please note, however, that some of these
+customized machine Makefile are contributed by users.  Since both
+compilers, OS configurations, and LAMMPS itself keep changing, their
+settings may become outdated:
+
+
+.. parsed-literal::
+
+   make mac             # build serial LAMMPS on a Mac
+   make mac_mpi         # build parallel LAMMPS on a Mac
+   make intel_cpu       # build with the USER-INTEL package optimized for CPUs
+   make knl             # build with the USER-INTEL package optimized for KNLs
+   make opt             # build with the OPT package optimized for CPUs
+   make omp             # build with the USER-OMP package optimized for OpenMP
+   make kokkos_omp      # build with the KOKKOS package for OpenMP

+Include packages in build
+=========================
+
+In LAMMPS, a package is a group of files that enable a specific set of
+features.  For example, force fields for molecular systems or
+rigid-body constraints are in packages.  In the src directory, each
+package is a sub-directory with the package name in capital letters.
+
+An overview of packages is given on the :doc:`Packages <Packages>` doc
+page.  Brief overviews of each package are on the :doc:`Packages details <Packages_details>` doc page.
+
+When building LAMMPS, you can choose to include or exclude each
+package.  In general there is no need to include a package if you
+never plan to use its features.
+
+If you get a run-time error that a LAMMPS command or style is
+"Unknown", it is often because the command is contained in a package,
+and your build did not include that package.  Running LAMMPS with the
+:doc:`-h command-line switch <Run_options>` will print all the included
+packages and commands for that executable.
+
+For the majority of packages, if you follow the single step below to
+include it, you can then build LAMMPS exactly the same as you would
+without any packages installed.  A few packages may require additional
+steps, as explained on the :doc:`Build extras <Build_extras>` doc page.
+

+
+The mechanism for including packages is simple but different for CMake
+versus make.
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D PKG_NAME=value          # yes or no (default)
+
+Examples:
+
+
+.. parsed-literal::
+
+   -D PKG_MANYBODY=yes
+   -D PKG_USER-INTEL=yes
+
+All standard and user packages are included the same way.  Note that
+USER packages have a hyphen between USER and the rest of the package
+name, not an underscore.
+
+See the shortcut section below for how to install many packages at
+once with CMake.
+
+.. note::
+
+   If you toggle back and forth between building with CMake vs
+   make, no packages in the src directory can be installed when you
+   invoke cmake.  CMake will give an error if that is not the case,
+   indicating how you can un-install all packages in the src dir.
+
+**Traditional make**\ :
+
+
+.. parsed-literal::
+
+   cd lammps/src
+   make ps                    # check which packages are currently installed
+   make yes-name              # install a package with name
+   make no-name               # un-install a package with name
+   make mpi                   # build LAMMPS with whatever packages are now installed
+
+Examples:
+
+
+.. parsed-literal::
+
+   make no-rigid
+   make yes-user-intel
+
+All standard and user packages are included the same way.
+
+See the shortcut section below for how to install many packages at
+once with make.
+
+.. note::
+
+   You must always re-build LAMMPS (via make) after installing or
+   un-installing a package, for the action to take effect.
+
+.. note::
+
+   You cannot install or un-install packages and build LAMMPS in a
+   single make command with multiple targets, e.g. make yes-colloid mpi.
+   This is because the make procedure creates a list of source files that
+   will be out-of-date for the build if the package configuration changes
+   within the same command.  You can include or exclude multiple packages
+   in a single make command, e.g. make yes-colloid no-manybody.
+
+**CMake and make info**\ :
+
+Any package can be included or excluded in a LAMMPS build, independent
+of all other packages.  However, some packages include files derived
+from files in other packages.  LAMMPS checks for this and does the
+right thing.  Individual files are only included if their dependencies
+are already included.  Likewise, if a package is excluded, other files
+dependent on that package are also excluded.
+
+When you download a LAMMPS tarball or download LAMMPS source files
+from the Git or SVN repositories, no packages are pre-installed in the
+src directory.
+
+.. note::
+
+   Prior to Aug 2018, if you downloaded a tarball, 3 packages
+   (KSPACE, MANYBODY, MOLECULE) were pre-installed in the src directory.
+   That is no longer the case, so that CMake will build as-is without the
+   need to un-install those packages.
+
+
+----------
+
+
+**CMake shortcuts for installing many packages**\ :
+
+Instead of specifying all the CMake options via the command-line,
+CMake allows initializing the variable cache using script files. These
+are regular CMake files which can manipulate and set variables, and
+can also contain control flow constructs.
+
+LAMMPS includes several of these files to define configuration
+"presets", similar to the options that exist for the Make based
+system. Using these files you can enable/disable portions of the
+available packages in LAMMPS. If you need a custom preset you can take
+one of them as a starting point and customize it to your needs.

+
+   Running cmake this way manipulates the variable cache in your
+   current build directory. You can combine multiple presets and options
+   in a single cmake run, or change settings incrementally by running
+   cmake with new flags.
+
+**Example:**
+
+
+.. parsed-literal::
+
+   # build LAMMPS with most commonly used packages, but then remove
+   # those requiring additional library or tools, but still enable
+   # GPU package and configure it for using CUDA. You can run.
+   mkdir build
+   cd build
+   cmake -C ../cmake/presets/most.cmake -C ../cmake/presets/nolib.cmake -D PKG_GPU=on -D GPU_API=cuda ../cmake
+
+   # to add another package, say BODY to the previous configuration you can run:
+   cmake -D PKG_BODY=on .
+
+   # to reset the package selection from above to the default of no packages
+   # but leaving all other settings untouched. You can run:
+   cmake -C ../cmake/presets/no_all.cmake .
+
+
+----------
+
+
+**Make shortcuts for installing many packages**\ :
+
+The following commands are useful for managing package source files
+and their installation when building LAMMPS via traditional make.
+Just type "make" in lammps/src to see a one-line summary.
+
+These commands install/un-install sets of packages:
+
++-----------------------------------+-----------------------------------------------------+
+| make yes-all                      | install all packages                                |
++-----------------------------------+-----------------------------------------------------+
+| make no-all                       | un-install all packages                             |
++-----------------------------------+-----------------------------------------------------+
+| make yes-standard or make yes-std | install standard packages                           |
++-----------------------------------+-----------------------------------------------------+
+| make no-standard or make no-std   | un-install standard packages                        |
++-----------------------------------+-----------------------------------------------------+
+| make yes-user                     | install user packages                               |
++-----------------------------------+-----------------------------------------------------+
+| make no-user                      | un-install user packages                            |
++-----------------------------------+-----------------------------------------------------+
+| make yes-lib                      | install packages that require extra libraries       |
++-----------------------------------+-----------------------------------------------------+
+| make no-lib                       | un-install packages that require extra libraries    |
++-----------------------------------+-----------------------------------------------------+
+| make yes-ext                      | install packages that require external libraries    |
++-----------------------------------+-----------------------------------------------------+
+| make no-ext                       | un-install packages that require external libraries |
++-----------------------------------+-----------------------------------------------------+
+
+which install/un-install various sets of packages.  Typing "make
+package" will list all the these commands.
+
+.. note::
+
+   Installing or un-installing a package works by simply copying
+   files back and forth between the main src directory and
+   sub-directories with the package name (e.g. src/KSPACE, src/USER-ATC),
+   so that the files are included or excluded when LAMMPS is built.
+
+The following make commands help manage files that exist in both the
+src directory and in package sub-directories.  You do not normally
+need to use these commands unless you are editing LAMMPS files or are
+:doc:`installing a patch <Install_patch>` downloaded from the LAMMPS web
+site.
+
+Type "make package-status" or "make ps" to show which packages are
+currently installed.  For those that are installed, it will list any
+files that are different in the src directory and package
+sub-directory.
+
+Type "make package-installed" or "make pi" to show which packages are
+currently installed, without listing the status of packages that are
+not installed.
+
+Type "make package-update" or "make pu" to overwrite src files with
+files from the package sub-directories if the package is installed.
+It should be used after a :doc:`patch has been applied <Install_patch>`,
+since patches only update the files in the package sub-directory, but
+not the src files.
+
+Type "make package-overwrite" to overwrite files in the package
+sub-directories with src files.
+
+Type "make package-diff" to list all differences between pairs of
+files in both the src dir and a package dir.

+Optional build settings
+=======================
+
+LAMMPS can be built with several optional settings.  Each sub-section
+explain how to do this for building both with CMake and make.

+
+
+----------
+
+
+.. _cxx11:
+
+C++11 standard compliance test
+------------------------------------------
+
+The LAMMPS developers plan to transition to make the C++11 standard the
+minimum requirement for compiling LAMMPS.  Currently this only applies to
+some packages like KOKKOS while the rest aims to be compatible with the C++98
+standard.  Most currently used compilers are compatible with C++11; some need
+to set extra flags to switch.  To determine the impact of requiring C++11,
+we have added a simple compliance test to the source code, that will cause
+the compilation to abort, if C++11 compliance is not available or enabled.
+To bypass this check, you need to change a setting in the makefile or
+when calling CMake.
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D DISABLE_CXX11_REQUIREMENT=yes
+
+You can set additional C++ compiler flags (beyond those selected by CMake)
+through the CMAKE\_CXX\_FLAGS variable. Example for CentOS 7:
+
+
+.. parsed-literal::
+
+   -D CMAKE_CXX_FLAGS="-O3 -g -fopenmp -DNDEBUG -std=c++11"
+
+**Makefile.machine setting**\ :
+
+
+.. parsed-literal::
+
+   LMP_INC = -DLAMMPS_CXX98
+
+
+----------
+
+
+.. _fft:
+
+FFT library
+---------------------
+
+When the KSPACE package is included in a LAMMPS build, the
+:doc:`kspace\_style pppm <kspace_style>` command performs 3d FFTs which
+require use of an FFT library to compute 1d FFTs.  The KISS FFT
+library is included with LAMMPS but other libraries can be faster.
+LAMMPS can use them if they are available on your system.
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D FFT=value              # FFTW3 or MKL or KISS, default is FFTW3 if found, else KISS
+   -D FFT_SINGLE=value       # yes or no (default), no = double precision
+   -D FFT_PACK=value         # array (default) or pointer or memcpy
+
+.. note::
+
+   The values for the FFT variable must be in upper-case.  This is
+   an exception to the rule that all CMake variables can be specified
+   with lower-case values.
+
+Usually these settings are all that is needed.  If CMake cannot find
+the FFT library, you can set these variables:
+
+
+.. parsed-literal::
+
+   -D FFTW3_INCLUDE_DIRS=path  # path to FFTW3 include files
+   -D FFTW3_LIBRARIES=path     # path to FFTW3 libraries
+   -D MKL_INCLUDE_DIRS=path    # ditto for Intel MKL library
+   -D MKL_LIBRARIES=path
+
+**Makefile.machine settings**\ :
+
+
+.. parsed-literal::
+
+   FFT_INC = -DFFT_FFTW3         # -DFFT_FFTW3, -DFFT_FFTW (same as -DFFT_FFTW3), -DFFT_MKL, or -DFFT_KISS
+                                 # default is KISS if not specified
+   FFT_INC = -DFFT_SINGLE        # do not specify for double precision
+   FFT_INC = -DFFT_PACK_ARRAY    # or -DFFT_PACK_POINTER or -DFFT_PACK_MEMCPY
+
+# default is FFT\_PACK\_ARRAY if not specified
+
+
+.. parsed-literal::
+
+   FFT_INC =       -I/usr/local/include
+   FFT_PATH =      -L/usr/local/lib
+   FFT_LIB =       -lfftw3             # FFTW3 double precision
+   FFT_LIB =       -lfftw3 -lfftw3f    # FFTW3 single precision
+   FFT_LIB =       -lmkl_intel_lp64 -lmkl_sequential -lmkl_core  # MKL with Intel compiler
+   FFT_LIB =       -lmkl_gf_lp64 -lmkl_sequential -lmkl_core     # MKL with GNU compier
+
+As with CMake, you do not need to set paths in FFT\_INC or FFT\_PATH, if
+make can find the FFT header and library files.  You must specify
+FFT\_LIB with the appropriate FFT libraries to include in the link.
+
+**CMake and make info**\ :
+
+The `KISS FFT library <http://kissfft.sf.net>`_ is included in the LAMMPS
+distribution.  It is portable across all platforms.  Depending on the
+size of the FFTs and the number of processors used, the other
+libraries listed here can be faster.
+
+However, note that long-range Coulombics are only a portion of the
+per-timestep CPU cost, FFTs are only a portion of long-range
+Coulombics, and 1d FFTs are only a portion of the FFT cost (parallel
+communication can be costly).  A breakdown of these timings is printed
+to the screen at the end of a run using the :doc:`kspace\_style pppm <kspace_style>` command.  The :doc:`Run output <Run_output>`
+doc page gives more details.
+
+FFTW is a fast, portable FFT library that should also work on any
+platform and can be faster than the KISS FFT library.  You can
+download it from `www.fftw.org <http://www.fftw.org>`_.  LAMMPS requires
+version 3.X; the legacy version 2.1.X is no longer supported.
+
+Building FFTW for your box should be as simple as ./configure; make;
+make install.  The install command typically requires root privileges
+(e.g. invoke it via sudo), unless you specify a local directory with
+the "--prefix" option of configure.  Type "./configure --help" to see
+various options.
+
+The Intel MKL math library is part of the Intel compiler suite.  It
+can be used with the Intel or GNU compiler (see FFT\_LIB setting above).
+
+Performing 3d FFTs in parallel can be time consuming due to data
+access and required communication.  This cost can be reduced by
+performing single-precision FFTs instead of double precision.  Single
+precision means the real and imaginary parts of a complex datum are
+4-byte floats.  Double precision means they are 8-byte doubles.  Note
+that Fourier transform and related PPPM operations are somewhat less
+sensitive to floating point truncation errors and thus the resulting
+error is less than the difference in precision. Using the -DFFT\_SINGLE
+setting trades off a little accuracy for reduced memory use and
+parallel communication costs for transposing 3d FFT data.
+
+When using -DFFT\_SINGLE with FFTW3 you may need to build the FFTW
+library a second time with support for single-precision.
+
+For FFTW3, do the following, which should produce the additional
+library libfftw3f.a
+
+
+.. parsed-literal::
+
+   make clean
+   ./configure --enable-single; make; make install
+
+Performing 3d FFTs requires communication to transpose the 3d FFT
+grid.  The data packing/unpacking for this can be done in one of 3
+modes (ARRAY, POINTER, MEMCPY) as set by the FFT\_PACK syntax above.
+Depending on the machine, the size of the FFT grid, the number of
+processors used, one option may be slightly faster.  The default is
+ARRAY mode.
+
+
+----------
+
+
+.. _size:
+
+Size of LAMMPS data types
+------------------------------------
+
+LAMMPS has a few integer data types which can be defined as 4-byte or
+8-byte integers.  The default setting of "smallbig" is almost always
+adequate.
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D LAMMPS_SIZES=value   # smallbig (default) or bigbig or smallsmall
+
+**Makefile.machine setting**\ :
+
+
+.. parsed-literal::
+
+   LMP_INC = -DLAMMPS_SMALLBIG    # or -DLAMMPS_BIGBIG or -DLAMMPS_SMALLSMALL
+
+# default is LAMMPS\_SMALLBIG if not specified
+**CMake and make info**\ :
+
+The default "smallbig" setting allows for simulations with:
+
+* total atom count = 2\^63 atoms (about 9e18)
+* total timesteps = 2\^63 (about 9e18)
+* atom IDs = 2\^31 (about 2 billion)
+* image flags = roll over at 512
+
+The "bigbig" setting increases the latter two limits.  It allows for:
+
+* total atom count = 2\^63 atoms (about 9e18)
+* total timesteps = 2\^63 (about 9e18)
+* atom IDs = 2\^63 (about 9e18)
+* image flags = roll over at about 1 million (2\^20)
+
+The "smallsmall" setting is only needed if your machine does not
+support 8-byte integers.  It allows for:
+
+* total atom count = 2\^31 atoms (about 2 billion)
+* total timesteps = 2\^31 (about 2 billion)
+* atom IDs = 2\^31 (about 2 billion)
+* image flags = roll over at 512 (2\^9)
+
+Atom IDs are not required for atomic systems which do not store bond
+topology information, though IDs are enabled by default.  The
+:doc:`atom\_modify id no <atom_modify>` command will turn them off.  Atom
+IDs are required for molecular systems with bond topology (bonds,
+angles, dihedrals, etc).  Thus if you model a molecular system with
+more than 2 billion atoms, you need the "bigbig" setting.
+
+Image flags store 3 values per atom which count the number of times an
+atom has moved through the periodic box in each dimension.  See the
+:doc:`dump <dump>` doc page for a discussion.  If an atom moves through
+the periodic box more than this limit, the value will "roll over",
+e.g. from 511 to -512, which can cause diagnostics like the
+mean-squared displacement, as calculated by the :doc:`compute msd <compute_msd>` command, to be faulty.
+
+Note that the USER-ATC package and the USER-INTEL package are currently
+not compatible with the "bigbig" setting. Also, there are limitations
+when using the library interface. Some functions with known issues
+have been replaced by dummy calls printing a corresponding error rather
+than crashing randomly or corrupting data.
+
+Also note that the GPU package requires its lib/gpu library to be
+compiled with the same size setting, or the link will fail.  A CMake
+build does this automatically.  When building with make, the setting
+in whichever lib/gpu/Makefile is used must be the same as above.
+
+
+----------
+
+
+.. _graphics:
+
+Output of JPG, PNG, and movie files
+--------------------------------------------------
+
+The :doc:`dump image <dump_image>` command has options to output JPEG or
+PNG image files.  Likewise the :doc:`dump movie <dump_image>` command
+outputs movie files in MPEG format.  Using these options requires the
+following settings:
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D WITH_JPEG=value      # yes or no
+                             # default = yes if CMake finds JPEG files, else no
+   -D WITH_PNG=value       # yes or no
+                             # default = yes if CMake finds PNG and ZLIB files, else no
+   -D WITH_FFMPEG=value    # yes or no
+                             # default = yes if CMake can find ffmpeg, else no
+
+Usually these settings are all that is needed.  If CMake cannot find
+the graphics header, library, executable files, you can set these
+variables:
+
+
+.. parsed-literal::
+
+   -D JPEG_INCLUDE_DIR=path    # path to jpeglib.h header file
+   -D JPEG_LIBRARIES=path      # path to libjpeg.a (.so) file
+   -D PNG_INCLUDE_DIR=path     # path to png.h header file
+   -D PNG_LIBRARIES=path       # path to libpng.a (.so) file
+   -D ZLIB_INCLUDE_DIR=path    # path to zlib.h header file
+   -D ZLIB_LIBRARIES=path      # path to libz.a (.so) file
+   -D FFMPEG_EXECUTABLE=path   # path to ffmpeg executable
+
+**Makefile.machine settings**\ :
+
+
+.. parsed-literal::
+
+   LMP_INC = -DLAMMPS_JPEG
+   LMP_INC = -DLAMMPS_PNG
+   LMP_INC = -DLAMMPS_FFMPEG
+
+   JPG_INC = -I/usr/local/include   # path to jpeglib.h, png.h, zlib.h header files if make cannot find them
+   JPG_PATH = -L/usr/lib            # paths to libjpeg.a, libpng.a, libz.a (.so) files if make cannot find them
+   JPG_LIB = -ljpeg -lpng -lz       # library names
+
+As with CMake, you do not need to set JPG\_INC or JPG\_PATH, if make can
+find the graphics header and library files.  You must specify JPG\_LIB
+with a list of graphics libraries to include in the link.  You must
+insure ffmpeg is in a directory where LAMMPS can find it at runtime,
+i.e. a dir in your PATH environment variable.
+
+**CMake and make info**\ :
+
+Using ffmpeg to output movie files requires that your machine
+supports the "popen" function in the standard runtime library.
+
+.. note::
+
+   On some clusters with high-speed networks, using the fork()
+   library calls (required by popen()) can interfere with the fast
+   communication library and lead to simulations using ffmpeg to hang or
+   crash.
+
+
+----------
+
+
+.. _gzip:
+
+Read or write compressed files
+-----------------------------------------
+
+If this option is enabled, large files can be read or written with
+gzip compression by several LAMMPS commands, including
+:doc:`read\_data <read_data>`, :doc:`rerun <rerun>`, and :doc:`dump <dump>`.
+
+**CMake variables**\ :
+
+
+.. parsed-literal::
+
+   -D WITH_GZIP=value       # yes or no
+                            # default is yes if CMake can find gzip, else no
+   -D GZIP_EXECUTABLE=path  # path to gzip executable if CMake cannot find it
+
+**Makefile.machine setting**\ :
+
+
+.. parsed-literal::
+
+   LMP_INC = -DLAMMPS_GZIP
+
+**CMake and make info**\ :
+
+This option requires that your machine supports the "popen()" function
+in the standard runtime library and that a gzip executable can be
+found by LAMMPS during a run.
+
+.. note::
+
+   On some clusters with high-speed networks, using the fork()
+   library calls (required by popen()) can interfere with the fast
+   communication library and lead to simulations using compressed output
+   or input to hang or crash. For selected operations, compressed file
+   I/O is also available using a compression library instead, which is
+   what the :ref:`COMPRESS package <PKG-COMPRESS>` enables.
+
+
+----------
+
+
+.. _align:
+
+Memory allocation alignment
+---------------------------------------
+
+This setting enables the use of the posix\_memalign() call instead of
+malloc() when LAMMPS allocates large chunks or memory.  This can make
+vector instructions on CPUs more efficient, if dynamically allocated
+memory is aligned on larger-than-default byte boundaries.
+On most current systems, the malloc() implementation returns
+pointers that are aligned to 16-byte boundaries. Using SSE vector
+instructions efficiently, however, requires memory blocks being
+aligned on 64-byte boundaries.
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D LAMMPS_MEMALIGN=value            # 0, 8, 16, 32, 64 (default)
+
+Use a LAMMPS\_MEMALIGN value of 0 to disable using posix\_memalign()
+and revert to using the malloc() C-library function instead.  When
+compiling LAMMPS for Windows systems, malloc() will always be used
+and this setting ignored.
+
+**Makefile.machine setting**\ :
+
+
+.. parsed-literal::
+
+   LMP_INC = -DLAMMPS_MEMALIGN=value   # 8, 16, 32, 64
+
+Do not set -DLAMMPS\_MEMALIGN, if you want to have memory allocated
+with the malloc() function call instead. -DLAMMPS\_MEMALIGN **cannot**
+be used on Windows, as it does use different function calls for
+allocating aligned memory, that are not compatible with how LAMMPS
+manages its dynamical memory.
+
+
+----------
+
+
+.. _longlong:
+
+Workaround for long long integers
+------------------------------------------------
+
+If your system or MPI version does not recognize "long long" data
+types, the following setting will be needed.  It converts "long long"
+to a "long" data type, which should be the desired 8-byte integer on
+those systems:
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D LAMMPS_LONGLONG_TO_LONG=value     # yes or no (default)
+
+**Makefile.machine setting**\ :
+
+
+.. parsed-literal::
+
+   LMP_INC = -DLAMMPS_LONGLONG_TO_LONG
+
+
+----------
+
+
+.. _exceptions:
+
+Exception handling when using LAMMPS as a library
+------------------------------------------------------------------
+
+This setting is useful when external codes drive LAMMPS as a library.
+With this option enabled LAMMPS errors do not kill the caller.
+Instead, the call stack is unwound and control returns to the caller,
+e.g. to Python.
+
+**CMake variable**\ :
+
+
+.. parsed-literal::
+
+   -D LAMMPS_EXCEPTIONS=value        # yes or no (default)
+
+**Makefile.machine setting**\ :

+Notes for building LAMMPS on Windows
+====================================
+
+* :ref:`General remarks <generic>`
+* :ref:`Running Linux on Windows <linux>`
+* :ref:`Using GNU GCC ported to Windows <gnu>`
+* :ref:`Using a cross-compiler <cross>`
+
+
+----------
+
+
+.. _generic:
+
+General remarks
+-----------------------------
+
+LAMMPS is developed and tested primarily on Linux machines.  The vast
+majority of HPC clusters and supercomputers today runs on Linux as well.
+Thus portability to other platforms is desired, but not always achieved.
+The LAMMPS developers strongly rely on LAMMPS users giving feedback and
+providing assistance in resolving portability issues. This particularly
+true for compiling LAMMPS on Windows, since this platform has significant
+differences with some low-level functionality.
+
+.. _linux:
+
+Running Linux on Windows
+------------------------------------
+
+So before trying to build LAMMPS on Windows, please consider if using
+the pre-compiled Windows binary packages are sufficient for your needs
+(as an aside, those packages themselves are build on a Linux machine
+using cross-compilers).  If it is necessary for your to compile LAMMPS
+on a Windows machine (e.g. because it is your main desktop), please also
+consider using a virtual machine software and run a Linux virtual machine,
+or - if have a recently updated Windows 10 installation - consider using
+the Windows subsystem for Linux, which allows to run a bash shell from
+Ubuntu and from there on, you can pretty much use that shell like you
+are running on an Ubuntu Linux machine (e.g. installing software via
+apt-get). For more details on that, please see :doc:`this tutorial <Howto_bash>`
+
+.. _gnu:
+
+Using GNU GCC ported to Windows
+-----------------------------------------
+
+One option for compiling LAMMPS on Windows natively, that has been known
+to work in the past is to install a bash shell, unix shell utilities,
+perl, GNU make, and a GNU compiler ported to Windows. The Cygwin package
+provides a unix/linux interface to low-level Windows functions, so LAMMPS
+can be compiled on Windows. The necessary (minor) modifications to LAMMPS
+are included, but may not always up-to-date for recently added functionality
+and the corresponding new code. A machine makefile for using cygwin for
+the old build system is provided. Using CMake for this mode of compilation
+is untested and not likely to work.
+
+When compiling for Windows do **not** set the -DLAMMPS\_MEMALIGN define
+in the LMP\_INC makefile variable and add -lwsock32 -lpsapi to the linker
+flags in LIB makefile variable. Try adding -static-libgcc or -static or
+both to the linker flags when your resulting LAMMPS Windows executable
+complains about missing .dll files. The CMake configuration should set
+this up automatically, but is untested.
+
+In case of problems, you are recommended to contact somebody with
+experience in using cygwin.  If you do come across portability problems
+requiring changes to the LAMMPS source code, or figure out corrections
+yourself, please report them on the lammps-users mailing list, or file
+them as an issue or pull request on the LAMMPS GitHub project.
+
+.. _cross:
+
+Using a cross-compiler
+----------------------------------
+
+If you need to provide custom LAMMPS binaries for Windows, but do not
+need to do the compilation on Windows, please consider using a Linux
+to Windows cross-compiler. This is how currently the Windows binary
+packages are created by the LAMMPS developers. Because of that, this is
+probably the currently best tested and supported way to build LAMMPS
+executables for Windows.  There are makefiles provided for the
+traditional build system, but CMake has also been successfully tested
+using the mingw32-cmake and mingw64-cmake wrappers that are bundled
+with the cross-compiler environment on Fedora machines. A CMake preset
+selecting all packages compatible with this cross-compilation build
+is provided. You likely need to disable the GPU package unless you
+download and install the contents of the pre-compiled `OpenCL ICD loader library <https://download.lammps.org/thirdparty/opencl-win-devel.tar.gz>`_
+into your MinGW64 cross-compiler environment. The cross-compilation
+currently will only produce non-MPI serial binaries.
+
+Please keep in mind, though, that this only applies to compiling LAMMPS.
+Whether the resulting binaries do work correctly is no tested by the
+LAMMPS developers.  We instead rely on the feedback of the users
+of these pre-compiled LAMMPS packages for Windows.  We will try to resolve
+issues to the best of our abilities if we become aware of them. However
+this is subject to time constraints and focus on HPC platforms.
+
+.. _native:
+
+Native Visual C++ support
+--------------------------------------
+
+Support for the Visual C++ compilers is currently not available. The
+CMake build system is capable of creating suitable a Visual Studio
+style build environment, but the LAMMPS code itself is not fully ported
+to support Visual C++. Volunteers to take on this task are welcome.
