The Halstead cluster will be unavailable beginning at Thursday, January 24th, 2019 at 8:00am, for emergency maintenance. The cluster is expected to return to full production by Thursday, January 24th, 2019 at 1:00pm.

During this time, Halstead will have critical security patches made to the operating system.

Any PBS jobs which request a walltime which would take them past Thursday, January 24th, 2019 at 8:00am will not start and will remain in the queue until after the maintenance is completed. Any jobs which are still running at Thursday, January 24th, 2019 at 8:00am will need to be terminated. Unfortunately, due to the critical security nature of the work, these patches cannot be postponed to allow for normal job completion.
