MPI Traffic Across Modules
--------------------------

Since in |SYSTEM_NAME| both supercomputing modules (Cluster and Booster) are part of the same InfiniBand fabric, there are no limitations when it comes to use the MPI of your choice. Both ParaStationMPI and OpenMPI work in heterogeneous jobs as long as the same MPI is used for all job components. Note, however, that IntelMPI is not available on the Booster, since it lacks CUDA-awareness and it makes therefore no sense to deploy it in that module.
