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. 

Course: Selecting software modules 

This course is given under NAISS, by staff working at the branches located at LUNARC and HPC2N.

Course: Introduction to Kebnekaise

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.

Summer break in project proposal processing

Apply no later than 30 June if you want project proposals processed before summer as nothing is processed during July.

Proposals will start being processed again in the first week of August.

You find the project rounds here in SUPR: https://supr.naiss.se/round/

Happy summer!

Course: Introduction to Linux, 2025-09-08

This 3-hour ONLINE course is an introduction to the Linux operating system (OS) that is used on most Swedish compute clusters, and is the most common OS in HPC clusters all over the planet. The course will consist of lectures, code-alongs, and interspersed exercises. It is given under NAISS by staff working at the branches UPPMAX, HPC2N, and LUNARC.

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.

You can connect by pointing your browser to: https://portal.hpc2n.umu.se

The software documentation has been migrated to the documentation website, https://docs.hpc2n.umu.se/ and can now be found there under the menu header "SOFTWARE". 

On 13 January 2025, Gaussian will disappear from Kebnekaise for non-UmU users.

For UmU users:
 - Send a support request via https://supr.naiss.se/support/login/?centre_resource=c1 and let us know that you need to use Gaussian.

For non-Umu users:
 - If you need to continue running Gaussian after that, you need to apply for time on a NAISS-system. You can find information on the NAISS systems here: https://supr.naiss.se/resource/

The HPC2N Center Local rounds for compute and storage are now open for proposals.

The start date of allocations are 2025-01-01.

End date for HPC2N Center Local 2024 rounds are 2024-12-15.

New location for the HPC2N documentation

The documentation pages has a new server and a new layout. You can find it here: https://docs.hpc2n.umu.se/
