We are currently experiencing file system server problems.
This causes problems with logins and any access to the file system.
We're working to get it back online but currently have no ETA for this.
UPDATE 2022-08-05 10:20
The problem has been solved and the system is back online working normally
Sorry for the problems this has caused

*UPDATE 2022-07-06 16:00*
File system is looking stable again, we'll continue to keep an eye on it at least until tomorrow.
*UPDATE 2022-07-08 10:30*
File system has been stable for two days so we consider it fully online as of now.
UPPMAX and HPC2N are organising a joint ONLINE workshop on how to run Python codes and install additional Python packages on the computer resources provided by these two HPC centres. Participants are encouraged to bring their particular software request for discussion as well.
The goal for the course is that you will be able to:
In this course, we begin with a short introduction to the Linux operating system (OS) that is used on HPC2N's compute cluster, and is the most common OS in HPC clusters. This part is only meant for complete beginners to the Linux operating system, and can be omitted if you are proficient already. See the schedule.
Abstract: In this talk, Kristoffer Carlsson, developer at Julia Computing in Sweden, will talk about the Julia language with particular emphasis on performance in an HPC setting. Topics mentioned will be Julia's compilation pipeline, SIMD, parallelism (shared and distributed memory), among others.
This event is free and will be online. The talk will be recorded.
This workshop targets programmers in both academia and industry who already have experience with basic MPI and are ready to take the next step to more advanced usage. Topics which will be covered include communicators, groups, derived data types, one-sided communication, non-blocking collectives and hybrid MPI+threading approaches. Lectures will be interleaved with hands-on exercises. All exercises will be written in C, but the instructors will be able to answer questions about MPI in Fortran and Python.
Follow-up Cooling maintenance computer hall, cluster down 2022-04-05 13:00
We plan to have the cluster up again later this evening around 19.00
*** UPDATE 16.00 ***
Kebnekaise is back up again and everything is back to normal
The cooling has failed in the computer hall causing an emergency power break.
We're investigating the reason and will try to get the cluster back as soon as possible.
* UPDATE 2022-04-04 16:30 *
The cluster is being brought up, this will take a while longer.
But more cooling-related work needs to be done tomorrow, so we have put a reservation on the cluster starting 2022-04-05 13:00.
This means that only short jobs will be allowed to start until after the next cooling work is finished and the system is safe to bring up fully.
----------------------------------
Update 2022-03-25 12:20 Maintenance ended and Kebenkaise is up and running again and the accessnodes are also open
----------------------------------
Updated 2022-03-25 07:10 We have done most of the work and the current plan is that Kebnekaise will be up after 12.00 today
----------------------------------
On Thursday 2022-03-24 from 05.00 there will be maintenance on the cooling system for the cluster compute datacenter.
At the same time we will also do maintenance on the parallel file system.
