Owens Information Transition

Owens cluster will be decommissioned on February 3, 2025. Some pages may still reference Owens after Owens is decommissioned , and we are in the process of gradually updating the content. Thank you for your patience during this transition

Batch

- --gpus-per-task is not working

Updated: This is fixed. 

Original Post:

After the recent Slurm upgrade, the option --gpus-per-task is currently not functioning as expected. Users attempting to submit jobs with this option may encounter the following error message:

salloc: error: Job submit/allocate failed: Requested node configuration is not available

As a workaround, users should use the --gpus-per-node option instead of --gpus-per-task. We have opened a ticket with the vendor about this issue. 

Rolling reboots on owens and pitzer starting 18 Aug 2021

We will have rolling reboots of Owens and Pitzer cluster, including login and compute nodes, starting from 9am on August 18, 2021. The rolling reboot is for urgent security updates.

The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect about a 10 minute outage of login nodes during the reboot of login nodes. If there are interactive jobs started from a login node and that login node is rebooted, then the job will be killed.
