cuFFTMp uses NVSHMEM. In order to interoperate with MPI, a bootstrap plugin is required. NVSHMEM ships with a bootstrap compatible with HPC-X. However, you can easily build you own bootstrap, compatible with another MPI implementation. To do so,
MPICC=mpicc DEST=myMPI make mpi_bootstrap
will download NVSHMEM, build the bootstrap library and place it in the myMPI folder.
After this, you can run any sample by
MPI_HOME=/path/to/my/mpi/ NVSHMEM_LIB="../../extra_bootstraps/myMPI" make run
which effectively place myMPI in your LD_LIBRARY_PATH.
