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.

There are three new nodes available on Kebnekaise.

Two of the new nodes have dual NVIDIA A100 GPUs and one is a many-core CPU node.

There are some notable differences with these nodes.

2023-06-09 A mishap with Slurm caused a loss of the job accounting data for Kebnekaise jobs today between 00:00 and 16:40

We can see no other effect on running jobs and the job queue are now open again after having been DOWN for 1 hour

If you see some other negative effect send us a support case and we'll help solving the issue

Sorry for the inconvenience that this may have caused.
