Power outage

Due to rewiring of the main power connection to the MIT building (the building that, among others, is housing HPC2N), there would be a power outage all day on 2025-07-03, but it should not have affected the Kebnekaise cluster. 

The outage is planned for: 2025-07-03, 7:00 - 16:00. 

UPDATE: 

Some things did not go as expected, which means that Kebnekaise, the web, various infrastructure, etc. lost power and is currently down. 

UPDATE: 2025-07-03, 12:35

Parts of the infrastructure, as well as the web, is coming up. 

We will have a maintenance window 2025-01-07 - 2025-01-10 for upgrading our project and user home file system.

This means that Kebnekaise will be drained from running jobs during the week before and no jobs will be allowed to run during the maintenance window. The login nodes will also be unavailable for the same reason.

*UPDATE 2025-01-10 16:20*

The file system upgrade is now done.

Login nodes and batch system is up and running.

On 13 January 2025, Gaussian will disappear from Kebnekaise for non-UmU users.

For UmU users:
 - Send a support request via https://supr.naiss.se/support/login/?centre_resource=c1 and let us know that you need to use Gaussian.

For non-Umu users:
 - If you need to continue running Gaussian after that, you need to apply for time on a NAISS-system. You can find information on the NAISS systems here: https://supr.naiss.se/resource/
