login node upgrades

The jhpce01.jhsph.edu login node will be taken offline for 1 hour on Tuesday, June 17th starting at 7:00PM in order to upgrade the node to a more powerful system.  This will not affect any jobs running on the cluster.  Access to cluster will remain available through the jhpce02.jhsph.edu login node.  If you intend to run interactive session that may extend into next week, we recommend that you login to jhpce02.jhsph.edu  to avoid disruption to your session.
