Declarations for NVSHMEM initialization/finalize class. gmxNvshmemHandle takes the MPI communicator and initializes the NVSHMEM over all the ranks involved in the given MPI communicator. This is a collective call for all the ranks in the given MPI comm. After NVSHMEM initialization all NVSHMEM APIs can be safely used.
