The Ohio Supercomputer Center (OSC) is experiencing an email delivery problem with several types of messages from MyOSC. 

OSC has conducted thorough validations to ensure the integrity of our backup data for the /fs/ess filesystem and are beginning full-scan backups of the home directories.

Emergency maintenance in OSC’s data center Feb 10 2022


OSC will shut down significant portions of the Owens and Pitzer clusters for several hours this afternoon (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 will provide relevant updates via email and in the Message of the Day. Please email if you have any questions or concerns.
