From octol at nsc.liu.se Wed Dec 3 10:04:21 2025 From: octol at nsc.liu.se (Filip Polbratt) Date: Wed, 3 Dec 2025 10:04:21 +0100 Subject: [Berzelius-users] Berzelius downtime on Wednesday 14th of January Message-ID: Dear Berzelius and Berzelius-Hopper Users, on 2026-01-14 07:00 we will start a maintenance window for several tasks that require significant downtime of the clusters. The primary reason for this downtime is electrical work which require the power to the computer room to be cut during the work. There will also be work done on the cooling loop providing cold water to the computer room. Berzelius, Berzelius Hopper, and the shared storage are affected by this downtime. We are scheduling this maintenance window to start on the 14th at 07:00 and to last to 14:00. We might be able to return the login nodes and some compute nodes to service earlier. However, this should not be expected and depended upon. === Additional topics === To better understand the users’ needs and to plan our upcoming training activities, we invite all Berzelius users to share their input through a short survey. Please take a moment to fill out the form here: https://nextcloud.liu.se/apps/forms/s/QWewNWroTaSDRjANqqXgii8m Thank you for helping us improve the Berzelius user experience. Best regards, Filip Polbratt NSC
