This seems to have worked. Thanks a lot!

Just in case someone else is interested, that debian bug thread suggests the 
following workaround:

Also, the "mpirun" in the script should be the OpenMPI one. The slurm mpirun 
didn't work for me (gave an error about openmpi not having been compiled with 
slurm's pmi support).
