job_container/tmpfs and srun.
by Phill Harvey-Smith 17 Jan '25

17 Jan '25

Hi all, On our setup we are using job_container/tmpfs to give each job it's own temp space. Since our compute nodes have reasonably sized disks for tasks that do a lot of disk I/O on user's data we have asked users to copy their data to the local disk at the beginning of the task and (if needed) copy it back at the end. This saves lots of NFS thrashing slowing down both the task and the NFS servers. However some of our users are having problems with this, their initial sbatch script … [View More]

Resource guarantees
by christopher.furbee＠jhuapl.edu 23 Dec '24

23 Dec '24

Hello, Long time SGE admin, new SLURM admin here. I recently started the transition of all my clusters from SGE to SLURM and everything was great until I hit the "Taco Bell" cluster (fake name). Taco Bell supports 4 projects and under SGE we had a priority system setup using projects to balance the queue. For the life of me I have been unable to replicate this in SLURM. We are looking to configure guaranteed resources based on the project. I had thought we could accomplish this with QOS and … [View More]

sending mails wit smail on rocky9
by Marcus Wagner 19 Dec '24

19 Dec '24

Hi all, I have a problem with sending mails on rocky 9 via Slurm. One needs to install s-nail to have "/bin/mail" being available. There are some caveats in smail. In the second part (for the message, when the job began) one need to pipe ( eg echo "") into $MAIL, even in a script with no input, s-nail wants to be interactive. but it suffices to echo an empty text to snail. Nonetheless, I don't get any mail through. it seems the, mailprog for some reason gets killed or errors out … [View More]for some other reason. While it is perfectionally working if run from the console :/ I all the time get in the slurmctld.log the following: 27212:[2024-12-19T15:54:54.935] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27213:[2024-12-19T15:54:54.945] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27214:[2024-12-19T15:54:54.945] error: MailProg returned error, it's output was '' 27395:[2024-12-19T15:55:55.540] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27396:[2024-12-19T15:55:55.551] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27397:[2024-12-19T15:55:55.551] error: MailProg returned error, it's output was '' 27438:[2024-12-19T15:56:55.981] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27439:[2024-12-19T15:56:55.981] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27440:[2024-12-19T15:56:55.992] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27441:[2024-12-19T15:56:55.992] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 9 27442:[2024-12-19T15:56:55.992] error: MailProg returned error, it's output was '' 27443:[2024-12-19T15:56:55.992] error: MailProg returned error, it's output was '' 27450:[2024-12-19T15:56:58.849] slurmscriptd: error: run_command: killing MailProg operation on shutdown 27451:[2024-12-19T15:56:58.859] slurmscriptd: _run_script: JobId=0 MailProg killed by signal 0 any hints?

job_container/tmpfs, TmpFS and TmpDisk usage
by Paul Musset 16 Dec '24

16 Dec '24

Hello, I have multiple questions about the usage of job_container/tmpfs, and the TmpFS and TmpDisk variables 1) If my job_container.conf files contains: ``` BasePath=/mnt/slurm_tmp Shared=true ``` is it important what I set TmpFS to in slurm.conf ? Should I set it to '/mnt/slurm_tmp' or '/tmp' ? 2) What size should I put in TmpDisk ? the size advertised by df ? 3) Finally, is there any recommended file system for the partition used as the job_container/tmpfs BasePath ? Best regards, … [View More]
