[howto] check overall partition usage

HPC Technical
3

Hi there,

And we have just added pestat as well (cf. Slurm_tools/pestat at master · OleHolmNielsen/Slurm_tools · GitHub ), from the upstream “Slurm related software” section (cf. Slurm Workload Manager - Download Slurm ).

pestat is another tool to check cluster usage, this time focusing on single nodes. @Yann.Sagon and @Pablo.Strasser have already talked about on this forum (cf. [Suggestion] Quick overview of gpu usage for nodes and partitions - #2 by Yann.Sagon and [Suggestion] Reserve one core per gpu on gpu nodes , respectively).

The default output including all ~250 nodes, here few lines:

Again, the -h option gives you plenty of explanation and other options to tweak the information reported.

Thx, bye,
