Stampede2 will be unavailable from 8 a.m. to 7:30 p.m. (CT) on Tuesday, 8 January 2019. System maintenance will be performed during this time.

If you submit a job before the maintenance, 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.
