[slurm-users] How are the results produced by 'seff'?

Hi,

With Slurm 24.11.5 for some jobs I am seeing differences between the memory usage reported by 'seff' and that shown by Prometheus as 'cgroup_memory_rss_bytes' (and ultimately reported by 'jobstats' [1]). Certainly at the University of Delft they seem to feel that the memory usage reported by 'seff' is unreliable [2].

Is that indeed the case?

Cheers,

Loris
