[slurm-users] Trying to Track Down root Usage
Hello all, Each week, I generate an automated report of the top users by CPU hours. This week, for whatever reason the user root accounted for a massive number of hours: Login Proper Name Used Account --- - - rootroot 28224 root I've tried to generate a report on what might account for this, but so far I'm stumped. For example, when I run a typical report: sacct -o jobid,jobname,start,end,NNodes,NCPUS,ReqMem,CPUTime,AveRSS,MaxRSS -S 2024-04-22 -E 2024-04-29 --user=root --units=G Nothing comes up (same if I change --user=root to --account=root). I'd appreciate any thoughts as to how to investigate or understand this. It may well be that I'm missing something fundamental. Warmest regards, Jason -- *Jason L.

Hi Jason, do or did you maybe have a reservation for user root in place? sreport accounts resources reserved for a user as well (even if not used by jobs) while sacct reports job accounting only.

Thanks, Juergen. I think you've solved it in one. I do have a root reservation on some nodes and was unaware that it would report that as CPU hour usage. Thanks!
