This was an annoying change:22.05.x RELEASE_NOTES: -- srun will no longer read in SLURM_CPUS_PER_TASK. This means you will implicitly have to specify --cpus-per-task on your srun calls, or set the new SRUN_CPUS_PER_TASK env var to accomplish the same thing. Here one can find relevant discussion: https://bugs.schedmd.com/show_bug.cgi?id=15632 I'll attach our cli-filter pre_submit function which works for us.
The discussion in bug 15632 concludes that this bug will only be fixed in 23.11. Your workaround looks nice, however, I have not been able to find any documentation of slurmctld calling any Lua functions named slurm_cli_pre_submit or slurm_cli_post_submit.
Some very similar functions are documented in https://slurm.schedmd.com/cli_filter_plugins.html for functions cli_filter_p_setup_defaults, cli_filter_p_pre_submit, and cli_filter_p_post_submit.
Can anyone she light on the relationship between Tommi's slurm_cli_pre_submit function and the ones defined in the cli_filter_plugins page?
Thanks, Ole
