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 --------------- -------------------- --------- --------- root root 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
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.
Best regards Jürgen

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!
