Hello List,

does anyone have experience with DefCpuPerGPU and jobs requesting multiple partitions? I would expect Slurm to select a partition from those requested by the job, then assign CPUs based on that partition's DefCpuPerGPU. But according to my observations, it appears that (at least sometimes), DefCpuPerGPU from another partition (also requested by the job, but not selected to execute it) is used to assign CPUs. I haven't done extensive testing to determine whether there's a pattern to this (e.g. always the first partition is used to calculate the number of CPUs), but I've found a bug report that seems to describe what I'm seeing: https://bugs.schedmd.com/show_bug.cgi?id=15238

Unfortunately, it appears to have been closed as invalid really quickly.

I'm on 23.02.5.

Best,

A.
