BUILDING AND PRECISION MODES
To build, edit the CUDA_ARCH, CUDA_PRECISION, CUDA_HOME variables in one of
the Makefiles. CUDA_ARCH should be set based on the compute capability 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
