Original Post:

We will have rolling reboots of all HPC clusters (Ascend, Cardinal, Owens, and Pitzer cluster), including login and compute nodes, starting from 9am on Oct 31 2024. The rolling reboot is for operating system and NVIDIA driver upgrades. 

The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the clusters. 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.

We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.
