There was a major power outage around 2012-05-03 10:15 which also affected our cluster machine room. The power is back and we are working on restoring the clusters. 

All running jobs on all our clusters were unfortunately lost.

The broken hardware has been replaced and the filesystem is now operational again.

The Abisko login node (t-mn01) will be rebooted during lunchtime this Wednesday, 18th of April. It shouldn't be down for more than 15 minutes.

Due to problems with the /pfs/nobackup filesystem both Akka and Abisko batch systems have been suspended.

One of the file servers has a broken moderboard and needs to be replaced.
ETA of a new moderboard is 2012-04-19.

We will investigate the other file servers for potential HW problems before taking the filesystem online again.

If everything else is ok we will run the filesystem with reduced capacity in the meantime.

The login node on Akka crashed on Saturday(2012-03-30), which affected access to the GPFS file system on the login node.

Matlab 2011b is now available on both Abisko and Akka. 

See our MATLAB page for more information.

The problem with MATLAB and java on abisko has now be solved!

Gaussian 09 revision C.01 is now available on Abisko too. It has been available on Akka for some time.

Please see the Release Notes for more information about the new release. Information about using Gaussian at HPC2N is available at our Gaussian support page.

The time to transition Abisko from the interim to the final system is here. During the
transition, Abisko will be unavailable starting from Wednesday February 15th 08:00. Assuming the transition goes smoothly, we expect to have the final system functional early next week.

During the migration from the interim system, we need to make a few changes that are disruptive to the cluster interconnect. The batch nodes will therefore not process any jobs from the above point in time until the transition is complete.

The final system of Abisko is now available and the queues have been restored. 

We still have some things to fix and tune so there may be some interruption the next couple of weeks.

Not all 318 nodes will be available at the moment. The interim system has not been upgraded to the new CPU:s and some other nodes are used for running some tests.

Some software may still be missing, but we are working on building them.
