Thank you for pointing me in the right direction.

The problem was that the OpenMPI installation in
"/home/manumachu/openmpi-4.0.3" was copied to
"/scratch/manumachu/openmpi-4.0.3/OPENMPI_INSTALL." While 'which mpirun'
and 'mpirun' work, It seems copying seems to break the slurm-mpirun

I did a fresh clean install in
"/scratch/manumachu/openmpi-4.0.3/OPENMPI_INSTALL." Now it works.

Kind Regards
