System Downtime May 12 2026
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, May 12, 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., May 12. 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.
Reboot of Public-Facing Systems for Security Fix
