| | 10 | ParaStationMPI provides support for inter-module communication in federated high-speed networks. Therefore, so-called gateway (GW) daemons bridge the MPI traffic between the modules. This mechanism is transparent to the MPI application, i.e., the MPI ranks see a common `MPI_COMM_WORLD` across all modules within the job. However, the user has to account for these additional GW resources during the job submission. An example SLURM Batch script illustrating the submission of heterogeneous pack jobs including the allocation of GW resources can be found [wiki:User_Guide/Batch_system#HeterogeneousjobswithMPIcommunicationacrossmodules here]. |
