 How do I compile with MPI support?
 
-> Ensure that your MPI implementation has been built with CUDA support and invoke CMake with `cmake -DMPI_ENABLED=ON -DBUILD_SAMPLES=ON ..`. Otherwise the build steps are the same. Assign exactly one process per GPU and run with, for example, `srun --gres=gpu:v100:<ngpus per node> --ntasks-per-socket=<ngpus per node / NICs per node> -n <total number of gpus> -N <number of nodes> ./mpitest` or equivalent `mpirun` command.
