Launch an MPI Application from a Singulairty* Container

For multiple node execution, use mpirun or other job manager (SLURM*, LFS*, TORQUE*) to launch the parallel job:

$ mpirun -n <processes_num> -hostlist <hosts> singularity exec <container_name>

During this launch, one MPI rank corresponds to one Singularity environment (see image below).
