Rolling reboot of Owens and Pitzer starting from July 11, 2022

We will have rolling reboots of Owens and Pitzer clusters including login and compute nodes, starting from 9AM Monday, July 11, 2022, to perform OS updates to address CVE-2022-1966 (https://access.redhat.com/security/cve/CVE-2022-1966). The rolling reboots won't affect any running batch jobs, but users may experience longer queue wait time than usual on both clusters. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

System Downtime June 21, 2022

A downtime for all OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, June 21, 2022. The downtime will affect the Pitzer and Owens Clusters, web portals, and HPC file servers. Client Portal (my.osc.edu) and state-wide licenses will be available during the downtime. In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., June 21, 2022. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.
