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/
We will have a maintenance window 2025-01-07 - 2025-01-10 for upgrading our project and user home file system.
This means that Kebnekaise will be drained from running jobs during the week before and no jobs will be allowed to run during the maintenance window. The login nodes will also be unavailable for the same reason.
*UPDATE 2025-01-10 16:20*
The file system upgrade is now done.
Login nodes and batch system is up and running.
SUNET will perform network management on the connection to Umeå University on 2024-12-06 somewhere between 07:00 and 22:00
Connection to HPC2N from outside Umeå University will be unreliable during that time window.
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.
We have now enabled our new AMD based nodes for production use.
The new nodes are AMD based cpus, both zen3 and zen4. Some have GPU's attached.
They are running Ubuntu Jammy (22.04).
We have
- one zen3 node with 2x64 cores
- two zen3 nodes with 2x24 cores and 2x Nvidia A100 gpus
- one zen3 node with 2x24 cores and 2x AMD MI100 gpus.

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.

Batch queues are down. We are currently investigating. The queues will be up again as soon as we have fixed the problem.
This news will be updated.
*UPDATE 2024-04-11 12:30*
The problem has been solved and the queues are up again.
On Wednesday 2024-03-20 09:00 we will perform a minor maintenance on Kebnekaise for about one hour.
The batch system will be unavailable for submitting new jobs or looking at the batch queue.
Running jobs will not be affected.
* UPDATE 09:30 *
Maintenance is done and everything is back online
Due to technical service on a router for UmU, external HPC2N connectivity is affected intermittently during 2004-02-26, 18:00-22:00.
Jobs that are already submitted should continue to run, and jobs in the queue should start, but anything that needs external connectivity (possibly some of the license servers) may be affected.
