System Downtime January 6 2026

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, January 6, 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., January 6. 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.

Update to Scratch File Purge Policy

To help alleviate recent storage stress on our scratch filesystem, we will be changing the purge period for scratch files from 90 days to 60 days. This means that any files not accessed within 60 days will be deleted. We invite you to share your comments or concerns during the public comment period, which will remain open until August 3. Please submit your feedback via https://www.osc.edu/resources/technical_support/supercomputing-policies/proposed_osc_policies_for_public_comments.
