CSCS informed us that the data centre will be undergoing maintenance on Wednesday, 27 September through Thursday, 28 September 2017, which will require a complete shutdown of Euler.

We will take this opportunity to do some additional maintenance on Euler itself the days before and after the CSCS maintenance. In particular, we will complete the upgrade Euler I and II to CentOS 7 (like Euler III) and prepare for the installation of Euler IV later this year.

As a consequence we plan that:

  • Euler compute nodes, login nodes, and storage system will be off-line from noon of Tuesday, 26 until Friday, 29 September; we will do out best to bring them back on-line ASAP.
  • Queues will be inactive throughout the weekend until Monday, 04 October 2017.

The exact times will be coordinated with CSCS and communicated here and by email in the weeks prior to the maintenance.

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.

Sorry for the inconvenience.
