Hi, I would like to soft-enforce license utilization only when the -L is set. My idea: check in the prolog if the license was requested and only if it were, set the environmental variables needed for the license.
I looked at all environmental variables set by slurm and did not find any related to the license as I was hoping. As a workaround, I could check scontrol show job $SLURM_JOB_ID | grep License and that would work, but (as discussed in other messages in this list) the documentation at https://slurm.schedmd.com/prolog_epilog.html say > Prolog and Epilog scripts should be designed to be as short as possible > and should not call Slurm commands (e.g. squeue, scontrol, sacctmgr, > etc). [...] Slurm commands in these scripts can potentially lead to > performance > issues and should not be used. This is a bit of a concern, since the prolog would be invoked for every job on the cluster, and it's a prolog (rather than the epilogue like discussed in earlier messages). So two questions: 1) is there a better workaround to check in the prolog if the current job requested a license and/or 2) would this kind of use of scontrol be okay or is indeed a concern Thanks!
