[slurm-users] seff: Memory usage > 100% ?

[Loris Bennett]

Hi,

Has anyone come across 'seff' producing a memory efficiency of more
than 100%?  E.g.

  $ seff -d 7379321
  Slurm data: JobID ArrayJobID User Group State Clustername Ncpus Nnodes Ntasks Reqmem PerNode Cput Walltime Mem ExitStatus
  Slurm data: 7379321  fakeuser fakegroup COMPLETED curta 16 1 16 1024000 1 158796 35275 2071808 0

  Job ID: 7379321
  Cluster: curta
  User/Group: fakeuser/fakegroup
  State: COMPLETED (exit code 0)
  Nodes: 1
  Cores per node: 16
  CPU Utilized: 1-20:06:36
  CPU Efficiency: 28.14% of 6-12:46:40 core-walltime
  Job Wall-clock time: 09:47:55
  Memory Utilized: 1.98 GB (estimated maximum)
  Memory Efficiency: 202.32% of 1000.00 MB (1000.00 MB/node)

This occurs with seff version 2.1.

Cheers,

Loris
