Hi!
> For the same time period, what is the reserved column say for "sreport -T > CPU -t MinPer cluster utilization"? Meaning, not by account. If that > Reserved is 0 for the cluster overall, then that does explain why it's also > zero for all accounts.

In the GRES/GPU Reserved case is always 0 in all cases, so it's consistent... but for me itlooked like a bug, so I reported it there... was it ok? Reserved time in sreport is time nodes are held idle (by the backfill > scheduler) to start the job. If you aren't using backfill, > We are using SchedulerType=sched/backfill. > or if all job submissions request about the same quantity of hardware > resources then it may always be zero. If there were some users submitting > large jobs and some small, then I would expect there to be some non-zero > time. > Users are requesting different amount of resources, but I'm not sure about the value of the "varience"... ;-) Anyway, I need to read and think why it should be 0 if all the users ask for the same amount of CPUs... even if they wait in the queue? I'm sure I'm missing something here... Thanks!
