Maintenance tomorrow (Friday March 3rd) 9am Pacific Time

March 3, 2011 by Katie Antypas | 0 Comments

We will need to take down the Hopper system tomorrow morning at 9am Pacific Time to install a crucial patch.  At that time we will also reconfigure some of the DVS service nodes to a more optimal setting.  The downtime is scheduled to last 8 hours.

Login nodes and access to the file systems will be available.  Users can also submit jobs, though the jobs will not start until the maintenance has been completed.
