Dear Team, I created a small cluster of 3 nodes on my VM ware to work on the CPU utilization concept. I created a user name= hpcuser01, and allocated GrpTresMin=cpu=59000040 -> CPU minutes and gpu=0 Now, when I checked his utilization using scontrol association cmd # scontrol show ass user=hpcuser01 | grep -n15 hpcuser01 "" Output: QOS=hpcuser01_test(11) UsageRaw=5789263754.153907 GrpJobs=N(0) GrpJobsAccrue=N(5) GrpSubmitJobs=N(5) GrpWall=N(1188290.27) GrpTRES=cpu=N(0),mem=N(0),energy=N(0),node=N(0),billing=N(0),fs/disk=N(0),vmem=N(0),pages=N(0),gres/gpu=N(0) GrpTRESMins=cpu=59000040(59001152),mem=N(293429427523),energy=N(0),node=N(1993778),billing=N(96073808),fs/disk=N(0),vmem=N(0),pages=N(0),gres/gpu=1(0) GrpTRESRunMins=cpu=N(0),mem=N(0),energy=N(0),node=46080(0),billing=N(0),fs/disk=N(0),vmem=N(0),pages=N(0)"" Here we can see that GrpTRESMins=cpu=59000040(59001152) after converting in Hours ( value /60) it will be: 983334(983352) CPU hours This means 983352 CPU hours have been used by hpcuser01 but, when I checked his utilization using sreport cmd #sreport -t hour --tres=cpu,gres/gpu,billing cluster AccountUtilizationByUser user=hpcuser01 start=2021-01-01T00:00:00 end=2024-02-20T23:59:59 -P | grep -iw -e billing -e cpu -e gres/gpu Output: cpu|979403 billing|1594902 gres/gpu|0 here I found that his utilisation is : 979403 I could like to understand why there is so much of a difference using two cmds to find out utilisation. Almost the difference is 979403 - 983352 = 3949 Request you to help me out with this. Regards, Prachi
