Just started working with OpenMPI / SLURM combo this morning. I can
successfully launch this job from the command line and it runs to
completion, but when launching from SLURM they hang.

They appear to just sit with no load apparent on the compute nodes even
though SLURM indicates they are running...

Are there any known issues of this nature involving OpenMPI and SLURM?

Thanks!
