[slurm-users] Limiting and tracking license TRES?

[Chin,David]

Hello, all:

Reading this old SLUG 2015 slide deck on Slurm TRES: https://slurm.schedmd.com/SLUG15/TRES.pdf
and the slurm.conf man page.

It seems to imply that TRES offers a way to place limits on
license consumption. From slide 3:

Limits on more resources other than CPU/Memory/Nodes
○ GRES, Licenses, etc

though the slide deck doesn't actually show examples of
reporting on or limiting the license TRES.

My Slurm 21.08.8 slurm.conf has:

AccountingStorageTRES=gres/gpu,gres/gpu:v100,license/stata
Licenses=stata:10

This works to limit Stata usage to no more than 10 licences
on the cluster.

However, trying to report does not show a valid TRES:

$ sreport cluster utilization --tres="license/stata"
sreport: fatal: No valid TRES given

or just

$ sreport cluster utilization --tres="license"
sreport: fatal: No valid TRES given

Nor can I set a GrpTRES, e.g.

$ sacctmgr modify account fooacct set grptres=license/stata=5
 Unknown option: grptres=license/stata=5
 Use keyword 'where' to modify condition

Is it possible to get sreports on license usage and/or limit license
usage? Am I missing something?

Thanks in advance,
    Dave
