Remove data from OSC Scratch file system
The scratch file system (/fs/scratch) is very full. Please help reduce your scratch file system usage by deleting data that is no longer needed; compressing infrequently accessed data and identifying important data that needs be moved to OSC's other file system. OSC may perform emergency file deletion to maintain the overall health of the service, if needed.

We will be upgrading ondemand.osc.edu and class.osc.edu from RHEL 8 to RHEL 9. It is expected to cause approximately 30 minutes of downtime per instance between 9am and 10am on Monday April 28. Both instances will be upgraded simultaneously. As part of this maintenance, OnDemand will also be upgraded from version 4.0.2 to 4.0.3.
System Downtime May 13 2025
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, May 13 2025. 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., May 13. 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.
