OSC is currently troubleshooting issues with ondemand.osc.edu ondemand.osc.edu will be non-functional until we resolve the issues. Contact oschelp@osc.edu with questions.

A downtime for all OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, March 22, 2022. The downtime will affect the Pitzer and Owens Clusters, web portals, and HPC file servers. Client Portal (my.osc.edu) and state-wide licenses will be available during the downtime. In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., March 22, 2022.

OSC will shut down significant portions of the Owens and Pitzer clusters for several hours on Thursday, Feb. 10 to conduct emergency maintenance work on power systems in the data center. Jobs running on impacted nodes will be terminated when this work begins. OSC will issue refunds as needed for any impacted jobs. Additionally, due to reduced capacity on both clusters, queued jobs will experience delays until the maintenance is complete and the scheduler has a chance to clear out any backlog. We apologize for the inconvenience.

We have been experiencing inconsistent performance degradation of ESS filesystem (/fs/ess), starting from 12/22/2021. Jobs might be impacted. We are working with vendor on this.
