You can of course build LAMMPS yourself with any of the accelerator
You can, of course, build LAMMPS yourself with any of the accelerator
packages for your platform.
The build.py script will build LAMMPS for the various accelerlator
packages using the Makefile.* files in this dir, which you can edit if
necessary for your platform. You must set the "lmpdir" variable at
the top of build.py to the home directory of LAMMPS as installed on
your system. Then typing, for example,
your system. Note that the build.py script hardcodes the arch setting
for the USER-CUDA package, which should be matched to the GPUs on your
system, e.g. sm_35 for Kepler GPUs. For the GPU package, this setting
is in the Makefile.gpu.* files, as is the CUDA_HOME variable which
should point to where NVIDIA Cuda software is installed on your
system.
Once the Makefiles are in place, then typing, for example,
python build.py cpu gpu
will build executables for the CPU (no accelerators), and 3 GPU
variants (double, mixed, single precision). See the list
of possible targets at the top of the build.py script.

(double, mixed, single precision) of the GPU package. See the list of
possible targets at the top of the build.py script.
Note that the build.py script will un-install all packages in LAMMPS,
then only install the ones needed for the benchmark. The Makefile.*
files in this dir are copied into lammps/src/MAKE, as a dummy
Makefile.foo, so they will not conflict with makefiles that may
already be there. The build.py script also builds the auxiliary
GPU and USER-CUDA library as needed.
