Just a thought: could it be parallel debugging of slurm itself, e.g., slurmctld? > The reason I looked into this is that a few of our nodes recently ran > out of disk space, and I was a bit surprised when realizing that our > Slurm packages used over 500 MB. That cluster is using Slurm 17.02, Wow, that was a bit! In our slurm 17.02 installation, it uses ~ 140 MiB on the compute nodes. (Still a fair bit, though.) -- Cheers, Bjørn-Helge Mevik, dr. scient, Department for Research Computing, University of Oslo
