Scratch Space Purge Schedule Update: Changing to Daily Removals

Due to ongoing scratch space challenges and high utilization, the data purge frequency is changing from every Wednesday to daily. Files and data that have not been accessed for 60 days or more will be automatically removed from the system every day. Please ensure that you regularly back up or move any important data to your project or permanent storage directories to prevent unintended loss.

System Downtime August 11 2026

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 11, 2026. The downtime will affect the Pitzer, Cardinal and Ascend Clusters, web portals, the state-wide licenses and HPC file servers. MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., August 11. 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.
