Hammer Winter Maintenance

February 11, 2020  8:00am – 11:59pm


The Hammer Cluster maintenance is complete and the cluster is back in service.


The Hammer cluster will be unavailable beginning on Tuesday, February 11th, 2020 at 8:00am, for scheduled maintenance. The cluster will return to full production by Tuesday, February 11th, 2019 at 11:59pm.

During this time, Hammer’s primary batch scheduler will be switched from PBS/Torque to Slurm. This is a necessary upgrade and will require faculty and students to modify how they interact with the batch system. Please see the updated Hammer user guide for more information.


Any PBS jobs which request a walltime which would take them past the above times will not begin, and due to the batch scheduler change, any jobs in the queue which have not been run will be deleted.
