error and output files

Hi all, I have a program (for example x.x). When I run it as "x.x -I input -o output", I will get an "output" file, as well as output and error files from slurm. However, all the content of slurm output file is in the "output" file (and there are some extra content), so it is a waste to print the slurm output. Is it possible to set directives so that slurm only print error file? Thank you very much. Michael Morgan

Why is my job killed when ResumeTimeout is reached instead of it being requeued?
by Xaver Stiensmeier 09 Dec '24

09 Dec '24

Dear Slurm-user list, when a job fails because the node startup fails (cloud scheduling), the job should be re-queued: Resume Timeout Maximum time permitted (in seconds) between when a node resume request is issued and when the node is actually available for use. Nodes which fail to respond in this time frame will be marked DOWN and the jobs scheduled on the node requeued. however, instead of requeuing the job, it is killed.

I am unsure why that is not happening. The power down request is sent by the ResumeFailProgram. We have SlurmctldParameters=idle_on_node_suspend activated, but that shouldn't affect Resume, I guess.

Hi, I have munge running on the controller and nodes fine, all tests passed. I have slurmctld running on the controller ok after checking the logs /var/spool/slurmctld was not created which I assume should have happened via the rpm install? Anyway I cant get slurmd to run on the warewulf nodes and cant find any log to check? How to fault find this? regards Steven

multiple conf-server entries for sackd
by Brian Andrus 03 Dec '24

03 Dec '24

Not sure anyone would know, but... If you are running slurm in HA mode (multiple SlurmctldHost entries) is it possible to point sackd to more than one using the --conf-server option? So either specify --conf-server more than once, or have a comma-delimited list of them? The docs are a little light about that. Brian Andrus

We are pleased to announce the availability of the Slurm 24.11 release. To highlight some new features in 24.11: - New gpu/nvidia plugin. This does not rely on any NVIDIA libraries, and will build by default on all systems. It supports basic GPU detection and management, but cannot currently identify GPU-to-GPU links, or provide usage data as these are not exposed by the kernel driver. - Add autodetected GPUs to the output from "slurmd -C". - Added new QOS-based reports to "sreport".… [View More]
