The JL Cluster compute nodes and job scheduler will be shutdown on June 1, 2018. At that time, you will still be able to login to the head node.
The JL Cluster shared storage will become read-only on June 1, 2018. We will make a final backup of the data at that time, to be owned by Dr. Lukes. That backup will lose any special files (symbolic links are the most common user-owned special file).
The JL Cluster will be shutdown on June 30, 2018. Prior to that date, you may copy out any important data that you wish to keep for future work.
