Description Susan Chacko 2015-09-17 02:06:18 MDT 
I have a question about the output of sacct and sreport. Here's an example for a single hour:

sacct -pna --format User,Account,Partition,JobID,NCPUS,CPUTime,CPUTimeRaw,State,Start,End --start=2015-04-26T11:00:00 --end=2015-04-26T12:00:00

[susanc@biowulf2 ~]$ sreport Cluster AccountUtilizationByUser start=2015-04-26T11:00:00 end=2015-04-26T12:00:00

  biowulf              sb                                  480          0
  biowulf              sb    susanc    Susan Chacko        480          0


As you see, sacct reports CPU Time of  230520 seconds =~ 64 hrs. sreport reports 480 minutes = 8 hrs. It looks like sreport is reporting the actual utilization of CPU during that one hour time period (8 cpus * 1 hr = 8 hrs), while sacct is reporting the total CPU used by any jobs that ran during that time period, including the CPU which was utilized outside that hour? Do I have that right?

And, related, are there sacct flags I could use to get the same output as I'm getting from sreport?

Thanks!
Susan.

Hi,
   the answer to your first question is yes. If you want to get the same output
from sacct as sreport you have to use the -T option of sacct with the start and
end time given.
