We need to do a global maintenance of the Euler cluster to install security patches, upgrade the network and perform a final migration / sync of the "work" file system to a new storage system.

Therefore

Euler will be OFFLINE from 08:00 Tuesday 5 April until 14:00 Thursday 7 April

As usual, batch queues will be inactivated prior to the maintenance to ensure that no jobs get killed when the cluster is shut down. Short jobs can still run until the cluster is offline. There is no action required on your part.

Sorry for the inconvenience

Please watch this page for regular updates before, during and after the maintenance.
