Re: [slurm-users] Allow SFTP on a specific compute node

Outside the context of slurm, you could add exceptions to /etc/security/access.conf. This depends on where pam_access.so appears in /etc/pam.d/sshd. I believe we’re using the config recommended in the pam_slurm_adopt documentation. There are a number of caveats: you need system root to

[slurm-users] Limit job detail in scontrol without limiting squeue

2021-05-12 Thread Burian, John
Hello, all, If a user does something silly like embed confidential information in pathnames, thinking that no one will see it because their directories are protected, that information could be leaked through “scontrol show job=<>”. Pathnames for the job script and output files appear in the

This doesn' t help you now, but Slurm 20.11 is expected to have "magnetic reservations," which are reservations that will adopt jobs that don't specify a reservation but otherwise meet the restrictions of the reservation: https://slurm.schedmd.com/SLUG20/Roadmap.pdf, search for "magnetic" John

I have some questions about the Slurm Perl API - Is it still actively supported? I see it's still in the source in Git. - Does anyone use it? If so, do you have a pointer to some example code? My immediate question is, for methods that take a data structure as an input argument, how does one

Re: [slurm-users] job priority keeping resources from being used?

Are you setting realistic job run times (sbatch –t )? Slurm won’t backfill low priority jobs (with low resource requirements) in front of a high priority job (blocked waiting on high resource requirements) if it thinks the low priority jobs will delay the eventual start of the high priority

To emphasize what Thomas wrote: backfill will only be useful if users submit jobs with realistic runtime limits. If every job is submitted with a default runtime of, for example, 7 days, then Slurm will not backfill your small jobs while it waits for the resources for the highest-priority large
