Sherlock will not be available on Wednesday, November 28th, 2018 from 8:00am to 6:00pm.
System maintenance and upgrades will be performed during this time. Access to Sherlock will be unavailable, logins will be disabled and jobs won’t run.
If you submit a job on Sherlock 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 a pending reason of
ReqNodeNotAvailable (“Required Node Not Available”) for those jobs.
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 shorter than usual.
