We are upgrading Kebnekaise compute and login nodes to Ubuntu Noble.

This will result in some older softwares to not be available anymore. We've tried to build everything that is currently used but when that isn't possible there should be newer versions available instead.

If something is missing despite our efforts, please send a support case through the SUPR support case interface (or mail support@hpc2n.umu.se) and let us know.

The ThinLinc access to kebnekaise-tl.hpc2n.umu.se is now working again.

The login node behind it has been upgraded to Ubuntu Noble (24.04)

We have moved the kebnekaise.hpc2n.umu.se login host to a new machine.

This machine has a different SSH host key: SHA256:PpomhGO7eeljmDUdcp9sJGm/8Ek1sTEOTP+BwSRQrRQ

You may have to change or remove the old entry for the Kebnekaise login node from the known_hosts file. On Linux (and usually also macOS) you find this file under the directory .ssh/ in your home directory. On Windows it will be under %UserProfile%\.ssh

The entry for the Kebnekaise login node could begin with any of these in your known_hosts file

Dear users,

we are doing some maintenance on Kebnekaise starting 2025-12-10 07:00.

Everything will be down, no jobs running and login nodes disabled.

This will take the whole day and we expect to have things up and running again late on the evening the same day.

Watch this news info for updates.

*** UPDATE 2025-12-10 13:20 ***

The kebnekaise.hpc2n.umu.se login node has been moved to a new machine, see separate news entry about that.

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.
