I'm actually trying to report cluster utilization in Slurm but i don't understand the metric CPU Minutes.

[root@XXXX]# sreport cluster Utilization Start=2018-12-01 End=2018-12-31
--------------------------------------------------------------------------------
Cluster Utilization 2018-12-01T00:00:00 - 2018-12-30T23:59:59
Usage reported in CPU Minutes
--------------------------------------------------------------------------------
  Cluster Allocate     Down PLND Dow      Idle Reserved  Reported
--------- -------- -------- -------- --------- -------- ---------
    linux   744460        0        0   8187049    54091   8985600

Am i supposed to divide that value by the numbers of threads/cpu ?

Thank you.

The man page for sreport explains the different columns and the default format (-t) is Minutes.

cluster Utilization

This report will display total usage divided by Allocated, Down, Idle, and Reserved time for selected clusters. Reserved time refers to time that a job was waiting for resources after the job had become eligible. If the value is not of importance for you the number should be grouped with idle time.

Your report period is 30 days having (30*24*60) 43200 minutes (December has 31 days / 44640 mins, but End=<OPT> defaults to the end of the previous day). 8985600 divided by 43200 makes 208. Does this correspond to the total amount of your CPUs or threads?

    This is precisely the total amount of threads, thanks you ;-) – m4hmud Jan 7 at 11:19
