As of 4:45 pm Tuesday, May 19, all the work noted below has been completed and both Hansen and Peregrine-1 have been returned to full service.
Thanks for your patience.
The Hansen and Peregrine-1 clusters will be unavailable beginning at 8:00 am on Tuesday, May 19, 2015, for scheduled maintenance. The clusters will return to full production by 6:00 pm the same day.
During this time, Peregrine1 and Hansen will have the operating system patched, and the PBS resource management system upgraded.
Any PBS jobs which request a walltime which would take them past 8:00 am on May 19 will not start and will remain in the queue until after the maintenance is completed.
