[slurm-users] Detecting non-MPI jobs running on multiple nodes

[Davide DelVento]

At my previous job there were cron jobs running everywhere measuring
possibly idle cores which were eventually averaged out for the
duration of the job, and reported (the day after) via email to the
user support team.
I believe they stopped doing so when compute became (relatively) cheap
at the expense of memory and I/O becoming expensive.

I know, it does not help you much, but perhaps something to think about
