with this change, the USER-INTEL package can be installed and
compiled without having to alter makefiles for adding -lpthread.
All "intel optimized" makefiles have been updated to have the
LRT feature enabled. This change will allow us to include the
USER-INTEL package in several automated testing configurations
and thus allows to detect incompatibilities and compilation issus faster.

bb3ee752e5 Added optional numpy access to atom data
The library interface was extended to provide direct access to atom data using
numpy arrays. No data copies are made and numpy operations directly manipulate
memory of the native code.

To keep this numpy dependency optional, all functions are wrapped into the
lammps.numpy sub-object which is only loaded when accessed.

dc7f1281b8 USER-DPD: Kokkos version of Const Temperature DPD isn't implemented yet
The Constant Energy DPD (DPDE) was our primary usage case, so only stubs
for the Constant Temperature case were included in Kokkos code so far.
The non-Kokkos version works fine for Constant Temperature DPD.

b3d6d9f8cf fix memory leak via NeighListKokkos::clean_copy()
There were several clean_copy() calls in pair
styles *outside device code*.
They seem to have been left over from an abandoned
effort to copy the Kokkos neighbor list as
a member of the pair style, instead of copying
out the individual views needed.
These leftover clean_copy() calls were setting
pointers to NULL that had not been freed,
leading to large memory leaks.
I've removed the clean_copy() function entirely,
and replaced it with the copymode flag system used
in many other Kokkos objects.
The copymode flag is only set to one in
functors that hold copies of the neighbor list.

641bf72f20 lib kokkos: Enable deterministic use of Random_XorShift*_Pool.
Add support for lock-free and deterministic use of Random_XorShift*_Pool
by giving state_idx selection and lock responsibility up to the
application.  Done by an overload of get_state() to take sate_idx as
an argument that the appplication guarantees is concurrently unique
and within the range of num_states that the application passed to init().
In other words, this allows the RNG state to be associated with some
application specific index, rather than a runtime arbitrary thread ID,
and thus the application can control which work is performed using
which RNG in a deterministic manner, regardless of which thread
performs the work.
2017-03-01 11:52:33 -05:00
6e26358ec3 lib kokkos bugfix: on a CUDA host, the random state wasn't preserved.
Random_XorShift*_Pool<Kokkos::Cuda>::free_state() has two purposes:
1) update the state value kept in the pool
2) unlock the state
For a CUDA host thread, ONLY skip step 2, not both.

b26a434a50 USER-DPD Kokkos: Add "#ifdef ALLOW_NON_DETERMINISTIC_SSA" toggle
SSA atom binning algorithm was adjusted to do as much work in
parallel while preserving deterministic behavior.  The final
step is done serially to preserve deterministic behavior.
An alternative would be to sort the contents of the bins so
that they are always in the same order.
2017-02-28 12:53:56 -05:00

37810bdc53 USER-DPD: move centroid bin of stencil_ssa to the first slot.
Eliminates a special case version of a loop just for Subphase 0.
NOTE: pair evaluation order changes, causing numerical differences!
This changed the order that close neighbors of ghosts are processed.

4b3197202b USER-DPD: Rework SSA to use a new neighbor list structure, ready for Kokkos
NOTE: pair evaluation order changes, causing numerical differences!
Atom pair processing order is fully planned out in npair_half_bin_newton_ssa
Makes the SSA neighbor list structure very different. Do not use by others!
Each local is in ilist, numneigh, and firstneigh four times instead of once.

Changes LAMMPS core code that had been previously changed for USER-DPD/SSA:
Removes ssaAIR[] from class Atom as it is now unused.
Removes ndxAIR_ssa[] from class NeighList as it is now unused.
Increases length of ilist[], numneigh[], and firstneigh[] if SSA flag set.

be166cb5bf USER-DPD: Use subphases when processing AIR zero (locals) in SSA.
NOTE: pair ordering was NOT changed, but tiny differences could occur.
2017-02-22 15:08:20 -05:00
ee83b755ea USER-DPD: Split the SSA stencil and neighbor list into subphases.
NOTE: pair evaluation order changes, causing numerical differences!
This enables processing neighbors in subphase groups that enforce
a geometrical seperation of pairs, allowing greater parallelism
once fix_shardlow (SSA) is converted to Kokkos.
2017-02-22 15:08:20 -05:00
ce2da5068b USER-DPD: renumber AIRs back to 1-7 for ghosts, and just 0 for locals.
This removes the the distinction between pure and impure locals.
Pure and impure locals messed up the directionality of half neighbor lists,
which turns out is crucial to the approach for SSA with kokkos.
2017-02-22 15:08:19 -05:00
641bb4bb16 USER-DPD: remove use of ssaAIR[], move coord2ssaAIR() to nbin_ssa.cpp

acc5bde0fe Removed printf's from FixRXKokkos and FixRX.
- Commented out the printf's in FixRXKokkos and FixRX used for
  active debugging.
2017-02-13 16:36:30 -05:00
799d55e097 Switched to operator()'s and Tag's for the Kokkos launch objects.
- Switched from using lambda functions to operator()'s with type tags
  in FixRxKokkos. The lambda's were giving big problems in Cuda with
  the memory objects. This required that all referenced views be members
  of the FixRXKokkos class.
- Add copymode controls to solve_reactions() to avoid the destructor
  freeing pointers carried forward from the copy constructor. Added
  the same to FixRX since its called, too.
2017-02-13 16:33:21 -05:00
4e9c8f4962 Update FixRXKokkos for Cuda build. Added inline and other KOKKOS macros.

macros for __host__ and __device__ functions and inlined functions.
- Changed several View definitions to match the disjoint memory spaces
that only come up with Cuda builds.
2017-02-13 16:33:21 -05:00
2f32c1a9af Switched to using Kokkos device data for ODE scratch data.
- Finished porting all scratch arrays to using the StridedArrayType
  template.
- Created a single, large Kokkos device array and using that for all
  scratch data passed into the StridedArrayType objects.
2017-02-13 16:33:20 -05:00
4ac7a5d1f2 Added Kokkos-like array datatype into RK4 and RHS in FixRXKokkos.
- Created an Array class that provides stride access for operator[]
  w/o needing Kokkos views. This was designed to avoid the performance
  issues encountered with Views and sub-views throughout the RHS and
  ODE solver functions.
2017-02-13 16:33:20 -05:00
93d99ec8d0 Added ODE diagnostics to FixRxKokkos using Kokkos managed data.
- Added the diagnostics performance analysis routine to FixRxKokkos
  using Kokkos views.
TODO:
  - Switch to using Kokkos data for the per-iteration scratch data.
    How to allocate only enouch for each work-unit and not all
    iterations? Can the shared-memory scratch memory work for this,
    even for large sizes?
2017-02-13 16:33:19 -05:00

f2d005fb8d Fixed errors in FixRxKokkos kokkos neighbor lists initialization and
usage and calls to computeLocalTemperature.

- Created request for kokkos neighbor list for fix and switched to
  that neighbor list datatype in computeLocalTemperature.
- Reconfigured pre_force and setup_pre_force to call a common
  solve_reactions() method to avoid duplicate code.
TODO:
  - Clean-up
  - Provide per-problem scratch data within kokkos framework (instead
    of C++ new/delete data).
2017-02-13 16:33:18 -05:00
0d57a1d831 Added setup_pre_force, pack/unpack methods to FixRxKokkos.
- Added a kokkos version of setup_pre_force that only sets dvector
  and then communicates that.
- Converted all for loops to parallel_for's in computeLocalTemperator()
  and setup_pre_force.
- Added pack/unpack forward/reverse methods with Kokkos host views.

TODO:
 - The Kokkos neighbor list is not working. Need to request a Kokkos
   neighbor list in ::init(). Then, replace objects like list->ilist[]
   with k_list->d_ilist().
2017-02-13 16:33:18 -05:00
acba25c383 Added kokkos datatypes to FixRxKokkos::computeLocalTemperature(...)
Added kokkos dual-view datatypes used in computeLocalTemperature and
pre_force (e.g., dpdThetaLocal) but still using the original host
pointers for the pack/unpack operations.

TODO:
- The Kokkos neighbor list is not working. Need to request a Kokkos
  neighbor list in ::init(). Then, replace objects like list->ilist[]
  with k_list->d_ilist().
- Add another template parameter for HALFTHREAD and create (automatic)
  atomic view of dpdThetaLocal and sumWeights.
- Add modify/sync comments and replace the host-only pointers in the
  pack/unpack methods.
2017-02-13 16:33:17 -05:00
843f3a9192 Updates to FixRxKokkos ...
- Added templated computeLocalTemp<>() to FixRxKokkos but still
  using the original host data pointers.
- Updated the copy-back to dvector operation to be the same with
  RK4 and RKF45 per discussion with J. Larentzos.
TODO:
  - Add kokkos data for computeLocalTemp and parallel_for loop.
2017-02-13 16:33:15 -05:00
2ea900df00 Updated FixRxKokkos to use kokkos-managed data objects.
- Switched to use kokkos dvector, mask, and dpdTheta views
  from atomKK.
2017-02-13 16:33:13 -05:00
70fa9189a8 Updated KOKKOS installer and updated USER-DPD FixRx to match KOKKOS version.
- Updated the KOKKOS installer to include the fix_rx_kokkos.[cpp,h].
- Updated the USER-DPD version of fix_rx.[cpp,h] to sync with the Kokkos
  version. Solves child->parent class dependencies.
2017-02-13 16:33:09 -05:00
41d3903f5a Added kokkos-managed parameters for FixRxKokkos.
- Added kokkos-managed parameter data for the kinetics equations.

98c66089a9 Merge pull request #8 from ibaned/pair-multi-lucy-rx-kokkos-rho
fix race condition on rho, thanks @ibaned
2017-01-10 15:25:21 -07:00
d26f1403cd fix race condition on rho
the main bug here is the use of a local
rho_i accumulator which later gets assigned
back to rho[i].
in parallel, atomic additions can happen to
rho[i] while the local accumulator is held;
those atomic additions are lost when
the accumulator is atomically assigned.
we instead initialize the accumulator to zero
and atomically add it back to rho[i].

one Kokkos kernel was not annotated consistently,
STACKPARAMS was essentially uninitialized and
confused with a local variable,
plus lots of variables were unused in some
of the Kokkos kernels.

8503ac22a8 Fixed error->all instead of error->one bug in USER-DPD/fix_shardlow.cpp.
During dynamic load balancing, the subdomains will not be uniform so the
bbox size test in USER-DPD/fix_shardlow.cpp may only be called by one rank.
Using error->one allows any rank to stop the simulation in this scenario.
Added rcut and bbox information to help in diagnostics.

cmake-buildsystem
-----------------
To use the cmake build system instead of the make-driven one, do:
```
cmake /path/to/lammps/source/cmake
```
(please note the cmake directory as the very end)
To enable package, e.g. GPU do
```
cmake /path/to/lammps/source/cmake -DENABLE_GPU=ON
```
cmake has many many options, do get an overview use the curses-based cmake interface, ccmake:
```
ccmake /path/to/lammps/source/cmake
```
(Don't forget to press "g" for generate once you are done with configuring)

LATTE package :link(LATTE),h4
[Contents:]
A fix command which wraps the LATTE DFTB code, so that molecular
dynamics can be run with LAMMPS using density-functional tight-binding
quantum forces calculated by LATTE.
More information on LATTE can be found at this web site:
"https://github.com/lanl/LATTE"_#latte_home. A brief technical
description is given with the "fix latte"_fix_latte.html command.
:link(latte_home,https://github.com/lanl/LATTE)
[Authors:] Christian Negre (LANL) and Steve Plimpton (Sandia). LATTE
itself is developed at Los Alamos National Laboratory by Marc
Cawkwell, Anders Niklasson, and Christian Negre.
[Install or un-install:]
Before building LAMMPS with this package, you must first download and
build the LATTE library. You can do this manually if you prefer;
follow the instructions in lib/latte/README. You can also do it in
one step from the lammps/src dir, using a command like these, which
simply invokes the lib/latte/Install.py script with the specified
args:
make lib-latte # print help message
make lib-latte args="-b" # download and build in lib/latte/LATTE-master
make lib-latte args="-p $HOME/latte" # use existing LATTE installation in $HOME/latte
make lib-latte args="-b -m gfortran" # download and build in lib/latte and
# copy Makefile.lammps.gfortran to Makefile.lammps
Note that 3 symbolic (soft) links, "includelink" and "liblink" and
"filelink", are created in lib/latte to point into the LATTE home dir.
When LAMMPS builds in src it will use these links. You should
also check that the Makefile.lammps file you create is apporpriate
for the compiler you use on your system to build LATTE.
You can then install/un-install the package and build LAMMPS in the
usual manner:
make yes-latte
make machine :pre
make no-latte
make machine :pre

Several extensions of the the dissipative particle dynamics (DPD)
method. Specifically, energy-conserving DPD (eDPD) that can model
non-isothermal processes, many-body DPD (mDPD) for simulating
vapor-liquid coexistence, and transport DPD (tDPD) for modeling
advection-diffuion-reaction systems. The equations of motion of these
DPD extensions are integrated through a modified velocity-Verlet (MVV)
algorithm.

Define a computation that assigns each atom a cluster ID.
Define a computation that assigns each atom a cluster, fragement,

A cluster is defined as a set of atoms, each of which is within the
cutoff distance from one or more other atoms in the cluster. If an
atom has no neighbors within the cutoff distance, then it is a 1-atom
cluster. The ID of every atom in the cluster will be the smallest
atom ID of any atom in the cluster.

A fragment is similarly defined as a set of atoms, each of
which has an explicit bond (i.e. defined via a "data file"_read_data.html,
the "create_bonds"_create_bonds.html command, or through fixes like
"fix bond/create"_fix_bond_create.html, "fix bond/swap"_fix_bond_swap.html,
or "fix bond/break"_fix_bond_break.html). The cluster ID or fragment ID
of every atom in the cluster will be set to the smallest atom ID of any atom
in the cluster or fragment, respectively.
An aggregate is defined by combining the rules for clusters and
fragments, i.e. a set of atoms, where each of it is within the cutoff
distance from one or more atoms within a fragment that is part of
the same cluster. This measure can be used to track molecular assemblies
like micelles.
Only atoms in the compute group are clustered and assigned cluster
IDs. Atoms not in the compute group are assigned a cluster ID = 0.
IDs. Atoms not in the compute group are assigned a cluster ID = 0.
For fragments, only bonds where [both] atoms of the bond are included
in the compute group are assigned to fragments, so that only fragmets
are detected where [all] atoms are in the compute group. Thus atoms
may be included in the compute group, yes still have a fragment ID of 0.
The neighbor list needed to compute this quantity is constructed each
time the calculation is performed (i.e. each time a snapshot of atoms
is dumped). Thus it can be inefficient to compute/dump this quantity
too frequently or to have multiple compute/dump commands, each of a

[Description:]
Fix {edpd/source} adds a heat source as an external heat flux to each
atom in a spherical or cuboid domain, where the {source} is in units
of energy/time. Fix {tdpd/source} adds an external concentration
source of the chemical species specified by {index} as an external
concentration flux for each atom in a spherical or cuboid domain,
where the {source} is in units of mole/volume/time.
This command can be used to give an additional heat/concentration
source term to atoms in a simulation, such as for a simulation of a
heat conduction with a source term (see Fig.12 in "(Li2014)"_#Li2014b)
or diffusion with a source term (see Fig.1 in "(Li2015)"_#Li2015b), as
an analog of a periodic Poiseuille flow problem.
If the {sphere} keyword is used, the {cx,cy,cz,radius} defines a
spherical domain to apply the source flux to.
If the {cuboid} keyword is used, the {cx,cy,cz,dLx,dLy,dLz} defines a
cuboid domain to apply the source flux to.

[Description:]
This fix style is a wrapper on the self-consistent charge transfer
density functional based tight binding (DFTB) code LATTE. If you
download and build LATTE, it can be called as a library by LAMMPS via
this fix to run dynamics or perform energy minimization using DFTB
forces and energies computed by LATTE.
LATTE is principally developed and supported by Marc Cawkwell and
co-workers at Los Alamos National Laboratory (LANL). See the full
list of contributors in the src/LATTE/README file.
To use this fix, the LATTE program needs to be compiled as a library
and linked with LAMMPS. LATTE can be downloaded (or cloned) from
"https://github.com/lanl/LATTE"_https://github.com/lanl/LATTE.
Instructions on how to download and build LATTE on your system can be
found in the lib/latte/README. Note that you can also use the "make
lib-latte" command from the LAMMPS src directory to automate this
process.
Once LAMMPS is built with the LATTE package, you can run the example
input scripts for molecular dynamics or energy minimization that are
found in examples/latte.
A step-by-step tutorial can be follwed at: "LAMMPS-LATTE
tutorial"_https://github.com/lanl/LATTE/wiki/Using-LATTE-through-LAMMPS
The {peID} argument is not yet supported by fix latte, so it must be
specified as NULL. Eventually it will be used to enable LAMMPS to
calculate a Coulomb potential as an alternative to LATTE performing
the calculation.
:line
LATTE is a code for performing self-consistent charge transfer
tight-binding (SC-TB) calculations of total energies and the forces
acting on atoms in molecules and solids. This tight-binding method is
becoming more and more popular and widely used in chemistry,
biochemistry, material science, etc.
The SC-TB formalism is derived from an expansion of the Kohn-Sham
density functional to second order in charge fluctuations about a
reference charge of overlapping atom-centered densities and bond
integrals are parameterized using a Slater-Koster tight-binding
approach. This procedure, which usually is referred to as the DFTB
method has been described in detail by ("Elstner"_#Elstner) and
("Finnis"_#Finnis) and coworkers.
The work of the LATTE developers follows that of Elstner closely with
respect to the physical model. However, the development of LATTE is
geared principally toward large-scale, long duration, microcanonical
quantum-based Born-Oppenheimer molecular dynamics (QMD) simulations.
One of the main bottlenecks of an electronic structure calculation is
the solution of the generalized eigenvalue problem which scales with
the cube of the system size O(N^3).
The Theoretical and Computer sciences divisions at Los Alamos National
Laboratory have accumulated large experience addressing this issue by
calculating the density matrix directly instead of using
diagonalization. We typically use a recursive sparse Fermi-operator
expansion using second-order spectral projection functions
(SP2-algorithm), which was introduced by Niklasson in 2002
("Niklasson2002"_#Niklasson2002), ("Rubensson"_#Rubensson),
("Mniszewski"_#Mniszewski). When the matrices involved in the
recursive expansion are sufficiently sparse, the calculation of the
density matrix scales linearly as a function of the system size O(N).
Another important feature is the extended Lagrangian framework for
Born-Oppenheimer molecular dynamics (XL-BOMD)
("Niklasson2008"_#Niklasson2008) ("Niklasson2014"_#Niklasson2014),
("Niklasson2017"_#Niklasson2017) that allows for a drastic reduction
or even a complete removal of the iterative self-consistent field
optimization. Often only a single density matrix calculation per
molecular dynamics time step is required, yet total energy stability
is well maintained. The SP2 and XL-BOMD techniques enables stable
linear scaling MD simulations with a very small computational
overhead. This opens a number of opportunities in many different
areas of chemistry and materials science, as we now can simulate
larger system sizes and longer time scales

This fix computes a global scalar which can be accessed by various

fix is "extensive".
No parameter of this fix can be used with the {start/stop} keywords of
the "run"_run.html command.
The DFTB forces computed by LATTE via this fix are imposed during an
energy minimization, invoked by the "minimize"_minimize.html command.
NOTE: If you want the potential energy associated with the DFTB
forces to be included in the total potential energy of the system (the
quantity being minimized), you MUST enable the
"fix_modify"_fix_modify.html {energy} option for this fix.
[Restrictions:]
This fix is part of the LATTE package. It is only enabled if LAMMPS
was built with that package. See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
You must use metal units, as set by the "units"_units command to use
this fix.
LATTE does not currently compute per-atom energy or per-atom virial
contributions. So they will not show up as part of the calculations
performed by the "compute pe/atom"_compute_pe_atom.html or "compute
stress/atom"_compute_stress_atom.html commands.
Currently, LAMMPS must be run in serial or as a single MPI task, to
use this fix. This is typically not a bottleneck, since LATTE will be
doing 99% or more of the work to compute quantum-accurate forces.
NOTE: NEB calculations can be done using this fix using multiple
replicas and running LAMMPS in parallel. However, each replica must
be run on a single MPI task. For details, see the "neb"_neb.html
command and -partition command-line explained in "Section
2.6"_Section_start.html#start_6 of the manual.

the velocity for the force evaluation:

shifted so that the wall-particle interaction energy is 0.0 at the
cutoff distance.
For the {lj93} and {lj126} styles, {epsilon} and {sigma} are the usual
Lennard-Jones parameters, which determine the strength and size of the
particle as it interacts with the wall. Epsilon has energy units.
Note that this {epsilon} and {sigma} may be different than any
{epsilon} or {sigma} values defined for a pair style that computes
particle-particle interactions.
The {lj93} interaction is derived by integrating over a 3d
half-lattice of Lennard-Jones 12/6 particles. The {lj126} interaction
is effectively a harder, more repulsive wall interaction.
For the {colloid} style, {epsilon} is effectively a Hamaker constant
with energy units for the colloid-wall interaction, {R} is the radius
of the colloid particle, {D} is the distance from the surface of the
colloid particle to the wall (r-R), and {sigma} is the size of a
constituent LJ particle inside the colloid particle. Note that the
cutoff distance Rc in this case is the distance from the colloid
particle center to the wall.
The {colloid} interaction is derived by integrating over constituent
LJ particles of size {sigma} within the colloid particle and a 3d
half-lattice of Lennard-Jones 12/6 particles of size {sigma} in the
wall.
For the {wall/harmonic} style, {epsilon} is effectively the spring
constant K, and has units (energy/distance^2). The input parameter
{sigma} is ignored. The minimum energy position of the harmonic
spring is at the {cutoff}. This is a repulsive-only spring since the
interaction is truncated at the {cutoff}
NOTE: For all of the styles, you must insure that r is always > 0 for
all particles in the group, or LAMMPS will generate an error. This
means you cannot start your simulation with particles on the region
surface (r = 0) or with particles on the wrong side of the region
surface (r < 0). For the {wall/lj93} and {wall/lj126} styles, the
energy of the wall/particle interaction (and hence the force on the
particle) blows up as r -> 0. The {wall/colloid} style is even more
restrictive, since the energy blows up as D = r-R -> 0. This means
the finite-size particles of radius R must be a distance larger than R
from the region surface. The {harmonic} style is a softer potential
and does not blow up as r -> 0, but you must use a large enough
{epsilon} that particles always reamin on the correct side of the
region surface (r > 0).

The {mdpd/rhosum} style computes the local particle mass density rho
for mDPD particles by kernel function interpolation.
The following coefficients must be defined for each pair of atom types

The {mdpd} style computes the many-body interactions between mDPD
particles following the formulations in
"(Li2013_POF)"_#Li2013_POF. The dissipative and random forces are in
the form same as the classical DPD, but the conservative force is
local density dependent, which are given by

where the first term in <font size="4">F<sup>C</sup></font> with a
negative coefficient A < 0 stands for an attractive force within an

The {tdpd} style computes the pairwise interactions and chemical
concentration fluxes for tDPD particles following the formulations in
"(Li2015_JCP)"_#Li2015_JCP. The time evolution of a tDPD particle is
governed by the conservation of momentum and concentration given by

The last 3 values must be repeated Nspecies times, so that values for
each of the Nspecies chemical species are specified, as indicated by
the "I" suffix. In the first pair_coeff example above for pair_style
tdpd, Nspecies = 1. In the second example, Nspecies = 2, so 3
additional coeffs are specified (for species 2).

[Example scripts]
There are example scripts for using all these pair styles in
examples/USER/meso. The example for an eDPD simulation models heat
conduction with source terms analog of periodic Poiseuille flow
problem. The setup follows Fig.12 in "(Li2014_JCP)"_#Li2014_JCP. The
output of the short eDPD simulation (about 2 minutes on a single core)
gives a temperature and density profiles as
:c,image(JPG/examples_edpd.jpg)
The example for a mDPD simulation models the oscillations of a liquid
droplet started from a liquid film. The mDPD parameters are adopted
from "(Li2013_POF)"_#Li2013_POF. The short mDPD run (about 2 minutes
on a single core) generates a particle trajectory which can
be visualized as follows.
:c,image(JPG/examples_mdpd_first.jpg,JPG/examples_mdpd.gif)
:c,image(JPG/examples_mdpd_last.jpg)
The first image is the initial state of the simulation. If you
click it a GIF movie should play in your browser. The second image
is the final state of the simulation.
The example for a tDPD simulation computes the effective diffusion
coefficient of a tDPD system using a method analogous to the periodic
Poiseuille flow. The tDPD system is specified with two chemical
species, and the setup follows Fig.1 in
"(Li2015_JCP)"_#Li2015_JCP. The output of the short tDPD simulation
(about one and a half minutes on a single core) gives the
concentration profiles of the two chemical species as

[Mixing, shift, table, tail correction, restart, rRESPA info]:
The styles {edpd}, {mdpd}, {mdpd/rhosum} and {tdpd} do not support
mixing. Thus, coefficients for all I,J pairs must be specified explicitly.
The styles {edpd}, {mdpd}, {mdpd/rhosum} and {tdpd} do not support
the "pair_modify"_pair_modify.html shift, table, and tail options.
The styles {edpd}, {mdpd}, {mdpd/rhosum} and {tdpd} do not write
information to "binary restart files"_restart.html. Thus, you need
to re-specify the pair_style and pair_coeff commands in an input script
that reads a restart file.
[Restrictions:]
The pair styles {edpd}, {mdpd}, {mdpd/rhosum} and {tdpd} are part of
the USER-MESO package. It is only enabled if LAMMPS was built with
that package. See the "Making LAMMPS"_Section_start.html#start_3

Styles with a {gpu}, {intel}, {kk}, {omp}, or {opt} suffix are
functionally the same as the corresponding style without the suffix.
They have been optimized to run faster, depending on your available
hardware, as discussed in "Section 5"_Section_accelerate.html
of the manual. The accelerated styles take the same arguments and
should produce the same results, except for round-off and precision
issues.
These accelerated styles are part of the GPU, USER-INTEL, KOKKOS,

LAMMPS was built with those packages. See the "Making

the first coefficient after {oxdna/hbond} (seq=seqdep in the above example) and the three coefficients
after {oxdna2/dh} (T=0.1, rhos=1.0, qeff=0.815 in the above example). When using a Langevin thermostat
e.g. through "fix langevin"_fix_langevin.html or "fix nve/dotc/langevin"_fix_nve_dotc_langevin.html
the temperature coefficients have to be matched to the one used in the fix.

Pair style {snap} computes interactions using the spectral
neighbor analysis potential (SNAP) "(Thompson)"_#Thompson20142.
Like the GAP framework of Bartok et al. "(Bartok2010)"_#Bartok20102,
"(Bartok2013)"_#Bartok2013 which uses bispectrum components
to characterize the local neighborhood of each atom
in a very general way. The mathematical definition of the
bispectrum calculation used by SNAP is identical
to that used by "compute sna/atom"_compute_sna_atom.html.
In SNAP, the total energy is decomposed into a sum over
atom energies. The energy of atom {i } is
atom energies. The energy of atom {i} is
expressed as a weighted sum over bispectrum components.

Styles with a {gpu}, {intel}, {kk}, {omp}, or {opt} suffix are
functionally the same as the corresponding style without the suffix.
They have been optimized to run faster, depending on your available
hardware, as discussed in "Section 5"_Section_accelerate.html
of the manual. The accelerated styles take the same arguments and
should produce the same results, except for round-off and precision
issues.
These accelerated styles are part of the GPU, USER-INTEL, KOKKOS,
USER-OMP and OPT packages, respectively. They are only enabled if
LAMMPS was built with those packages. See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
You can specify the accelerated styles explicitly in your input script
by including their suffix, or you can use the "-suffix command-line
switch"_Section_start.html#start_6 when you invoke LAMMPS, or you can
use the "suffix"_suffix.html command in your input script.
See "Section 5"_Section_accelerate.html of the manual for
more instructions on how to use the accelerated styles effectively.
