Ascend

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.

On Thursday evening OSC experienced an outage affecting the scratch and project storage systems. *This is resolved.* If you do not see the Project or Scratch filesystems in your filebrowser in OnDemand, use the "Restart Web Server" option in the help menu in the upper right.
