[slurm-users] Calculate the GPU usages

[Jeherul Islam]

Dear Loris,

Thanks for your reply. Here is the output for the same period but the
result is not matching.

#sacct --account=chemistry
--format=jobid,user,ElapsedRaw,state,AllocGRES,ncpus --starttime=2021-05-01
--endtime=2021-08-31  | grep j.mira| grep gpu| awk '{sum += $3} END {print
sum}'

*6835053          (6835053/60 = 113917 )*

# sreport cluster AccountUtilizationByUser cluster=**** user=j.mira
start=2021-05-01 end=2021-08-31 --tres="gres/gpu"
--------------------------------------------------------------------------------
Cluster/Account/User Utilization 2021-05-01T00:00:00 - 2021-08-30T23:59:59
