The NAISS Large Fall 2025 and LUMI Sweden Fall 2025 calls are open

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

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. 

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.

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/
