Wednesday 2024-06-12 15.00 - Thursday 2024-06-13 12.00

Akademiska Hus is performing a perodical revision of the power to the MIT-building.

This affects the power to the compute clusters at HPC2N including the access nodes.

The work requires the power to be turned off and thus all clusters will need to be drained and taken down.

We have therefor set a reservation on the clusters preventing any jobs from running during that time frame.

Due to technical service on a router for UmU, external HPC2N connectivity is affected intermittently during 2004-02-26, 18:00-22:00.

Jobs that are already submitted should continue to run, and jobs in the queue should start, but anything that needs external connectivity (possibly some of the license servers) may be affected.

We are going to upgrade the file system for projects and home directories, /proj/nobackup and /home.

There is a maintenance window for this from 2023-11-15 08:00 - 2023-11-15 17:00.

No jobs will be allowed to run during that period and login nodes will also be disabled.

 

This is synchronized with electrical and cooling maintenance work on 2023-11-16 to minimize total downtime.

 

*** UPDATE 2023-11-17 11:25 ***

The maintenance is now finished and batch system and login nodes are back online.

Maintenance on Kebnekaise 2023-10-12 - 2023-10-13

We will have a maintenance window on Kebnekaise 2023-10-12 - 2023-10-13 to upgrade the batch system. It is due to an important security update of SLURM (the workload manager/batch scheduler).

From 2023-10-12 08:00 no jobs will be allowed to run, this means that jobs will not be allowed to start if their requested time limit reaches into this service window.

The maintenance window is from 2023-10-12 08:00 to 2023-10-13 17:00, but we hope to be finished before that.
