[slurm-users] Job runtime

[Mahmood Naderan]

Hi,
I see that slurm reports a 35 min duration for a completed job (g09) like this

[mahmood at rocks7 ~]$ sacct -j 30 --format=start,end,elapsed,time
              Start                 End    Elapsed  Timelimit
------------------- ------------------- ---------- ----------
2018-03-14T06:07:17 2018-03-14T06:42:30   00:35:13   01:00:00
2018-03-14T06:07:17 2018-03-14T06:42:30   00:35:13


However, the program itself, which logs the run, says

 Job cpu time:       0 days  0 hours 48 minutes  5.9 seconds.

the job scripts contains

#SBATCH --ntasks=1
#SBATCH --cpus-per-task=2

Is there any idea about that time difference?
