Emergency maintenance in data center Feb 10 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.
