[slurm-users] [EXTERNAL] Help with developing a lua job submit script

[Amspaugh, Glenn Gregory]

My group uses  "-p short,batch"  in our submit scripts. Jobs will try to run in the short partition (4 hours or less, no more than 24 nodes per job) but if there's a wait and enough nodes open up in regular batch partition (4 days / 844 nodes max), the job will run over there. Really helps back fill keep idle nodes to a minimum on our main partition and short jobs get processed faster than waiting for the limited number of nodes in just the short partition.

Hello,

We are starting to think about developing a lua job submission script. For example, we are keen to route jobs requiring no more than 1 compute node (single core jobs and small parallel jobs) to a slurm shared partition. The idea being that "small" jobs can share a small set of compute nodes to try to prevent resource fragmentation in the cluster. Other "larger" jobs are routed to the default partition.

As a start I have dug out the example lua script provided by slurm, however I wondered if there was any experience in doing this sort of routing using a lua script. We would appreciate any advice from the slurm community, please.

Best regards,
David
