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

Course: Introduction to Kebnekaise, 20 January 2026

This iś an ONLINE course.

We begin with an introduction to HPC and HPC2N, before going on to a walk-through of the Kebnekaise system, including the newest hardware.

After that, we go through the module system and take a look at how to submit jobs. During the hands-on you will get the opportunity to try loading modules, compile a program, and submit a job to the Kebnekaise cluster. We will look at how to use both the different types of CPUs, and the different types of GPUs.

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.

HPC2N coffee chats

These informal coffee-chats, "HPC2N fika", are meant for HPC2N’s current and potential users.  

It is a chance for you to discuss any HPC-related problems associated with your research and to get advice from HPC2N’s application experts and other staff.  We usually start with a few updates about what is new at HPC2N and sometimes a talk by a researcher who uses Kebnekaise. After that the floor is open. 

These "HPC2N fikas” will in the fall of 2025 be on

OpenOnDemand at HPC2N

The OpenOnDemand portal is now in production at HPC2N and can be used to login and work on Kebnekaise.

It should offer a more direct way to work interactively with (among other): Jupyter, RStudio, MATLAB, VS Code, ...

It is still a work in progress, so expect there to be regular changes as well as minor bugs and things that are being ironed out.
