The HalsteadGPU cluster will be unavailable beginning at Thursday, January 31st, 2019 at 8:00am, for emergency maintenance. The cluster is expected to return to full production by Thursday, January 31st, 2019 at 4:20pm.
During this time, HalsteadGPU will have critical security patches made to the operating system.
Any PBS jobs which request a walltime which would take them past Thursday, January 31st, 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 31st, 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.
