[slurm-users] Inconsistencies in CPU time Reporting by sreport and sacct Tools

[KK via slurm-users]

I wish to ascertain the CPU core time utilized by user dj1 and dj. I have
tested with sreport cluster UserUtilizationByAccount, sreport job
SizesByAccount, and sacct. It appears that sreport cluster
UserUtilizationByAccount displays the total core hours used by the entire
account, rather than the individual user's cpu time. Here are the specifics:

Users dj and dj1 are both under the account mehpc.

In 2024-04-12 ~ 2024-04-15, dj1 used approximately 10 minutes of core time,
while dj used about 4 minutes. However, "sreport Cluster
UserUtilizationByAccount user=dj1 start=2024-04-12 end=2024-04-15" shows 14
minutes of usage. Similarly, "sreport job SizesByAccount Users=dj
start=2024-04-12 end=2024-04-15" hows about 14 minutes.
Using "sreport job SizesByAccount Users=dj1 start=2024-04-12
end=2024-04-15" or "sacct -u dj1 -S 2024-04-12 -E 2024-04-15 -o
"jobid,partition,account,user,alloccpus,cputimeraw,state,workdir%60" -X
|awk 'BEGIN{total=0}{total+=$6}END{print total}'" yields the accurate
values, which are around 10 minutes for dj1.

Attachment are the details.
