Stampede 2 status, November 28, 2017

Posted by David Littrell on Nov 15, 2017 12:09:26 PM

Stampede2 will be unavailable 28 Nov 2017 between 8:00AM and 7:30PM CST for maintenance.
If you submit a job and the time you request exceeds the time remaining until the maintenance begins, your job will run when the maintenance is over. The squeue command will report "ReqNodeNotAvailable" ("Required Node Not Available"). The showq utility will list the job as "BLOCKED" and report its status as "WaitNod" ("Waiting for Nodes"). Note that the hours leading up to the maintenance are an excellent time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be short.
