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
