args = one or more of the following keywords: {out}, {all}, {system}, {memory}, {communication}, {computes}, {dumps}, {fixes}, {groups}, {regions}, {variables}, {coeffs}, {styles}, {time}, or {configuration}

{out} values = {screen}, {log}, {append} filename, {overwrite} filename
|

[Description:]
|
|
|
|
Print out information about the current internal state of the running
|
|
LAMMPS process. This can be helpful when debugging or validating
|
|
complex input scripts. Several output categories are available and
|
|
one or more output category may be requested.
|
|
|
|
The {out} flag controls where the output is sent. It can only be sent
|
|
to one target. By default this is the screen, if it is active. The
|
|
{log} argument selects the log file instead. With the {append} and
|
|
{overwrite} option, followed by a filename, the output is written
|
|
to that file, which is either appended to or overwritten, respectively.
|
|
|
|
The {all} flag activates printing all categories listed below.
|
|
|
|
The {configuration} category prints some information about the
|
|
LAMMPS version as well as architecture and OS it is run on.
|
|
|
|
The {memory} category prints some information about the current
|
|
memory allocation of MPI rank 0 (this the amount of dynamically
|
|
allocated memory reported by LAMMPS classes). Where supported,
|
|
also some OS specific information about the size of the reserved
|
|
memory pool size (this is where malloc() and the new operator
|
|
request memory from) and the maximum resident set size is reported
|
|
(this is the maximum amount of physical memory occupied so far).
|
|
|
|
The {system} category prints a general system overview listing. This
|
|
includes the unit style, atom style, number of atoms, bonds, angles,
|
|
dihedrals, and impropers and the number of the respective types, box
|
|
dimensions and properties, force computing styles and more.
|
|
|
|
The {communication} category prints a variety of information about
|
|
communication and parallelization: the MPI library version level,
|
|
the number of MPI ranks and OpenMP threads, the communication style
|
|
and layout, the processor grid dimensions, ghost atom communication
|
|
mode, cutoff, and related settings.
|
|
|
|
The {computes} category prints a list of all currently defined
|
|
computes, their IDs and styles and groups they operate on.
|
|
|
|
The {dumps} category prints a list of all currently active dumps,
|
|
their IDs, styles, filenames, groups, and dump frequencies.
|
|
|
|
The {fixes} category prints a list of all currently defined fixes,
|
|
their IDs and styles and groups they operate on.
|
|
|
|
The {groups} category prints a list of all currently defined groups.
|
|
|
|
The {regions} category prints a list of all currently defined regions,
|
|
their IDs and styles and whether "inside" or "outside" atoms are
|
|
selected.
|
|
|
|
The {variables} category prints a list of all currently defined
|
|
variables, their names, styles, definition and last computed value, if
|
|
available.
|
|
|
|
The {coeffs} category prints a list for each defined force style
|
|
(pair, bond, angle, dihedral, improper) indicating which of the
|
|
corresponding coefficients have been set. This can be very helpful
|
|
to debug error messages like "All pair coeffs are not set".
|
|
|
|
The {styles} category prints the list of styles available in the
|
|
current LAMMPS binary. It supports one of the following options
|
|
to control which category of styles is printed out:
|
|
|
|
all
|
|
angle
|
|
atom
|
|
bond
|
|
compute
|
|
command
|
|
dump
|
|
dihedral
|
|
fix
|
|
improper
|
|
integrate
|
|
kspace
|
|
minimize
|
|
pair
|
|
region :ul
|
|
|
|
The {time} category prints the accumulated CPU and wall time for the
|
|
process that writes output (usually MPI rank 0).
|
