Dear slurm support, I encountered a weird behavior about the MaxRss field in the slurm account. For the concrete example sacct reports [1] a MaxRss of roughly 55.7G while the job had a mem limit of 32G. If one measures the MaxRss of the job script outside of slurm with the GNU time-tool (/usr/bin/time -v ...) you get a MaxRss of 28G which is about the half of the size sacct reports. Therefore, I want to ask you how the MaxRss field of sacct is calculated? Is there a factor inside the slurm value which one has to consider? How can the fact be explained that slurm reports a MaxRss of 56G which would be clear above the mem limit of 32G which is enforced by the slurm cgroups plugin? Thank you very much!
