Ascend

We've been experiencing some instability on the clusters (particularly Cardinal and Ascend) following the recent May 13 downtime, especially with parallel job processing. If you notice any unusual behavior with your jobs, please contact OSC Help.

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.
