Original Message:

The Carter cluster will be unavailable beginning at Tuesday, January 19th, 2016 at 7:00am, for scheduled maintenance. The cluster will return to full production by 7:00pm.

During this time, critical preventative maintenance needs to be performed on the cooling unit for Carter. Jobs that run past this time will be unable to complete.

Any PBS jobs which request a walltime which would take them past Tuesday, January 19th, 2016 at 7:00am will not start and will remain in the queue until after the maintenance is completed.
