Reminder: Biowulf transitioning from RHEL6/CentOS6 to RHEL7/CentOS7 in June

This is a reminder that on June 4 the Biowulf cluster, the Biowulf login 
node, and Felix will transition from the RHEL6/CentOS6 to the 
RHEL7/CentOS7 operating system. On June 4, the login node, compute nodes 
and Helix will be unavailable starting 8 am. Helix will be down briefly. 
The cluster will be available by 1 pm on June 4, likely earlier. Groups 
of nodes will be returned to the cluster after they are transitioned to 
the new operating system. Thus, for a day or two there will be fewer 
resources available on Biowulf than usual, but the cluster will be up 
and running.

Information about Felix will be sent in a separate email to NIMH Biowulf 
users.

There will be several significant changes once the systems transition to 
Centos7. For a detailed list of changes, see
