Change config file location of slurmdbd temporarily
by Sven Schulze 07 Jan '25

07 Jan '25

Hey all, Is there a way to change the location of the slurmdbd.conf temporarily when starting slurmdbd? For all other daemons I can specify "-f", but this doesn't seem to work for slurmdbd, is there a way to edit the build files to achieve this? Kind Regards, Sven

All GPUs are Usable if no Gres is Defined
by Jacob Gordon 04 Jan '25

04 Jan '25

Hello, We have a two node GPU cluster with 8 NVidia GPUs. GRES is currently configured and works if a user defines it within their sbtach/interactive job submission (--gres=gpu:3). Users only have access to the GPUs they request. However, when they omit “--gres=gpu:n”, they can use every GPU, which interferes with running jobs that used the gres option. I’m at a loss as to why this is happening. Can someone please look at our configuration to see if anything stands out?

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 accounts but so far we have failed. What we would like to end up with is; When project Gordita is running uncontested 100% of the cluster is available. While Gordita is running, if Crunchwrap submits their jobs we want the scheduler to prioritize those jobs until a 75% Gordita, 25% Crunchwrap balance of jobs is reached. No preempting or priority overriding, just as a Gordita job finishes, if Crunchwrap is less than 25%, start a Crunchwrap job. And then maintain that balance until one of the projects jobs are 100% completed. Any assistance or guidance is greatly appreciated.

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 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, Paul Musset Max Planck Institute for Brain Research
