At 12:00 noon on Tuesday, 24-Jul-2018, we will upgrade the network infrastructure for the CLASSE Compute Farm and the Wilson Lab East Module server room. Network access to the CLASSE Compute Farm -- including any interactive use of CLASSE GRID -- will be interrupted for about two hours, during our normal maintenance window.
Since this upgrade includes a small reconfiguration of the central CLASSE network switch, there is a chance that internal CLASSE networks will also be affected. If we encounter any problems, we will roll back the changes so that network service is restored by the end of the maintenance window at 2:00 PM.
Because of the planned network outage on 24-Jul-2018, the batch queues on the CLASSE Compute Farm have been disabled since Friday, 20-Jul-2018 at 5:00 PM. They will be re-enabled at the conclusion of the network outage, around 2:00 PM on Tuesday, 24-Jul-2018.
