Update on Cheyenne system status

August 12, 2019

Cheyenne continues to experience system stability issues introduced after the recent software upgrade, and vendors’ Level-3 support and CISL staff continue to aggressively work the problems. This afternoon, following the CESM tutorial, CISL staff will test some vendor-recommended changes on Cheyenne. Following those tests, we plan to make Cheyenne available to users over the weekend and into next week.

During a CESM polar tutorial next week with approximately 20 onsite attendees, we will repeat the procedure of halting all standard queues; running jobs will finish and other submissions will remain queued until the tutorial hands-on session is finished for the day. This process will be invoked for roughly two hours on Monday morning, Tuesday afternoon, and Wednesday afternoon. Casper will remain fully available to all users throughout the week.
