CSCS informed us that the data center will be undergoing a major power and cooling maintenance on Wednesday 19 October 2022, which will require a complete shutdown of Euler.
Tentative schedule (subject to change):
| Tue 18 Oct, early morning | Start of power-down procedure, Euler off-line |
| Wed 19 Oct, whole day | CSCS maintenance, Euler completely down |
| Thu 20 Oct, whole day | Power-on of networks, storage system, admin nodes |
| Fri 21 Oct, noon | Power-on of login nodes, access to storage possible; compute nodes still down |
| Sat 22 Oct – Sun 23 Oct | Power-on and testing of all compute nodes |
| Mon 24 Oct, afternoon | Gradual reactivation of batch queues: first 4h, then 24h, and finally 120h |
As usual, batch queues will be progressively inactivated in the days and hours prior to the maintenance, to ensure that no jobs get killed when the cluster is shut down. Short jobs can still run until the the cluster is taken off-line. You will not be able to access your data during the first phase of the maintenance window (Tuesday morning to Friday noon). If all goes well, Euler will start running jobs again in the afternoon of Monday, 24 October and will be fully operational in the evening.
This is for your information only. No action is required on your part.
We are sorry for the inconvenience.
We will update this page in the days before and during the maintenance. Please come back here to get the latest information.
