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.

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.

Best regards,

We are currently experiencing file system server problems.

This is blocking logins and is also affecting running jobs.

We're working to get it back online but currently have no ETA for this.

UPDATE 09:40
The problem with the file server has been solved and everything should work as normal now

Akademiska hus have a planned maintenance of the cooling systems for the HPC2N Infrastructure computer hall on 2023-02-01

We'll coordinate an upgrade of the central file system around their maintenance to minimize the time the cluster is draining jobs.

The combined maintenance window will therefore start on 2023-01-30 07:00 and according to our planning end on 2023-02-03 16:00

All Kebnekaise nodes, central storage and the login nodes will be unavailable during this time.
