See the examples/accelerate/README and make.list files for sample
Make.py commands that build LAMMPS with any or all of the accelerator
packages. As an example, here is a command that builds with all the
GPU related packages installed (GPU, KOKKOS with Cuda), including
settings to build the needed auxiliary GPU libraries for Kepler GPUs:
.. code-block:: bash
Make.py -j 16 -p omp gpu kokkos -cc nvcc wrap=mpi -gpu mode=double arch=35 -kokkos cuda arch=35 lib-all file mpi
The examples/accelerate directory also has input scripts that can be
used with all of the accelerator packages. See its README file for
details.
Likewise, the bench directory has FERMI and KEPLER and PHI
sub-directories with Make.py commands and input scripts for using all
the accelerator packages on various machines. See the README files in
those directories.
