Due to a network maintenance (replacement of central Ethernet switches in the LEE data center) on 2-3 December 2020, the Leonhard Open cluster needs to be completely shutdown. During this downtime we will also upgrade the firmware of the Lustre file system in Leonhard Open. We are therefore announcing that

The Leonhard Open cluster will be OFFLINE from 12:00 pm (noon) on Wednesday, 2 December 2020.

We expect to be again online in the morning of 4 December 2020.

As usual, batch queues will be inactivated before the maintenance to ensure that no job gets killed when the cluster is shutdown. Shorter jobs can continue to run if they can finish by the time the cluster is taken offline.

There is no action required on your part. This page will be updated before and during this maintenance.

We apologize for any inconvenience this may cause.
