BUILDING AND PRECISION MODES
To build, edit the CUDA_ARCH, CUDA_PRECISION, CUDA_HOME, NVCC, CUDA_INCLUD,
CUDA_LIB and CUDA_OPTS variables in one of the Makefiles. CUDA_ARCH should
be set based on the compute capability of your GPU. This can be verified by
running the nvc_get_devices executable after the build is complete.
Additionally, the GPU package must be installed and compiled for LAMMPS.
This may require editing the gpu_SYSPATH variable in the LAMMPS makefile.
