Hi Herbert, I believe the limit is per node (not per partition) whereas you want it per job. In other words, your users will be able to run jobs on other nodes.
There is no MaxCPUsPerJob option in the partition definition, but I believe you can make that restriction in other ways (at worst with a job_submit.lua but I think there would be a simpler way). Sorry not an answer, but hopefully a little nudge toward the solution Davide On Wed, Feb 26, 2025 at 11:37 AM Herbert Fruchtl via slurm-users < slurm-users@lists.schedmd.com> wrote: > We have a cluster with multi-core nodes (168) that can be shared by > multiple jobs at the same time.
