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.
Planned network maintenance Jan 28 2022
There is a planned network maintenance with OSC systems on 28 Jan 2022. It is expected to cause a loss of connection to OSC systems for up to 5 mins during the maintenance window of 5am-6am on 28 Jan 2022.
Please contact oschelp@osc.edu if there are any questions.
