[slurm-users] How can we put limits on interactive jobs?

We would like to put limits on interactive jobs (started by salloc) so that users don't leave unused interactive jobs behind on the cluster by mistake.

I can't offhand find any configurations that limit interactive jobs, such as enforcing a timelimit.

Perhaps this could be done in job_submit.lua, but I couldn't find any job_desc parameters in the source code which would indicate if a job is interactive or not.

Question: How do people limit interactive jobs, or identify orphaned jobs and kill them?

Thanks a lot, Ole
