Ascend

We will have rolling reboots of Ascend, Owens and Pitzer clusters including login and compute nodes, starting from 9AM Wednesday October 25, to perform NVIDIA driver and Slurm upgrades. At the start of the rolling reboot all login nodes will be unavailable for about 10 minutes. The rolling reboots won't affect any running batch jobs, but users may experience longer queue wait time than usual on the clusters.

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 8, 2023. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. MyOSC and state-wide licenses will be available during the downtime. See this link for more details: https://www.osc.edu/calendar/events/2023_08_08-system_downtime_august_8_2023

Beginning 9am on Wednesday, June 14, we will be having rolling reboots of all clusters (Owens, Pitzer, and Ascend). This includes both login and compute nodes and will be done to perform OS updates. Login nodes will be rebooted at 9am on June 14, which will leave them unavailable for approximately 5-10 minutes. The rolling reboots won't affect any running batch jobs, but users may experience longer than usual wait times on all clusters.
