[slurm-users] Backfill pushing jobs back

[David Baker]

Hi Chris,

Thank you for your reply. It isn't long since we upgraded to Slurm v19, however it sounds like we should start to actively look at v20 since this issue is causing significant problems on our cluster. We're download and install v20 on our dev cluster, and experiment.

Best regards,
David

This sounds like a problem that we had at NERSC (small jobs pushing back
multi-thousand node jobs), and we carried a local patch for which Doug
managed to get upstreamed in 20.02.x (I think it landed in 20.02.3, but
20.02.6 is the current version).

Hope this helps!
Chris
