Time: Tuesday 3.6.2025 (08:00 – 21:00) EEST

There will be a service break on Puhti starting on Tuesday June 3rd at 8:00, and ending at 21:00. During the service break there will be no access to the system including login nodes, web interface, and storage system.

In the service break a number of important maintenance operations and upgrades will be carried out, improving reliability and functionality of the system. This includes an upgrade to Slurm 24.05.

In this service break there are no changes that affect the usage of Puhti, and existing applications and scripts should continue to work after the break.

Jobs that can finish before the break will execute normally, and any jobs that are queuing when the service break starts will be able to run after it has finished.
