The Hansen, Coates, and Rossmann clusters will be unavailable beginning at 8:00am on Tuesday, January 7, 2014, for scheduled maintenance. The clusters will return to full production by 5:00pm, Wednesday, Janauary 8.
During this time, these systems will receive operating system patches, and an upgrade to the PBS resource management software.
Additionally, some installed software in "modules" will be updated, retired, and defaults changed. Watch the output of "module load" for notifications if any software that you use are affected.
See Software Stack Changes in January for more information.
Any PBS jobs which request a walltime which would take them past 8:00am on 1/7/2014 will not start and will remain in the queue until after the maintenance is completed.
