In normal MPI programs, **omit the `-pernode` directive** to run up to 16 MPI tasks per each node. In this example, we allocate 4 nodes via the express queue interactively. We set up the OpenMPI environment and interactively run the helloworld_mpi.x program. Note that the executable helloworld_mpi.x must be available within the same path on all nodes. This is automatically fulfilled on the /home and /scratch filesystem. -- GitLab
