Test to determine if MPI work or not

[ph-kev]

Hello,

I am trying to install ILAMB on a cluster following these instructions: https://www.ilamb.org/doc/install.html.

I am able to run ILAMB and I am passing the arguments below to SLURM.

- slurm_cpus_per_task: 8
- slurm_ntasks: 4
- slurm_mem: 64GB
- slurm_time: "2:00:00"

However, I can't tell if MPI is being used or not. Is there a simple way to determine if MPI is being used or not for ILAMB?
