The Cerebras system will be taken offline on Wednesday, March 20, to undergo a software upgrade, updating from version 2.0.3 to 2.1.x. Beginning at approximately 9:00 a.m. (CT), all jobs on the Cerebras system will be stopped and logins will become unavailable. The system is expected to be returned to use the next day, Thursday, March 21, at which time we will notify users. Please contact support@alcf.anl.gov with any questions, comments, or concerns.
