High Performance Computing Center North
On Tuesday (2014-09-16) we will start to do more large scale tests of our new center storage.
We have made a reservation of the system between Tuesday and Thursday for this.
Abisko will therefor be drained of jobs during this time.

Thursday Aug 28th we will performe some large scale tests of our new center storage.
To do this we have reserved ALL nodes of Abisko starting 09:30 CEST
The tests are expected to take a couple of hours after which the system will be back for normal use.
We recommend submitting jobs with shorter runtimes which will then fit nicely into the slots that become available due to draining the system.
UPDATE 2014-08-28 20:30 CEST
We just had a power outage this morning. All jobs running on both Akka and Abisko were interrupted. We are currently in the process of restoring the systems.
We hope to have all Akka compute nodes back in service by the end of today.
Abisko nodes may take longer. It is possible that we can get them back up today, but they may not be available until Thursday morning, due to the scheduled file system update tomorrow.

Quantum Espresso 5.1 has now been installed on both Abisko and Akka.

On Wednesday Aug 20th we will do the initial installation of our new cluster file system.
To do this we need to do some recabling on the interconnect of Abisko.
We will therefore drain the cluster of jobs so that it will be empty at 08:00
The system is estimated to be back in production on Thursday morning at the latest.
More information on the new file system will be annouced later.

Today (2014-07-19) we suffered a city-wide power failure around 15:27 CEST. This caused all of the Abisko and Akka nodes to lose power and shut down.
The clusters should be back in production again at approximately 21:00 CEST.

Abisko will be upgraded to the latest version of Slurm on Wed. 2014-06-11.
No jobs will be running during the upgrade.
All jobs in the queue should be preserved and start as soon as the upgrade is completed.

The batch server for Akka will be move to another system on Mar 25th
To do this we have to make sure no jobs are running and have therefor created a reservation that starts 08:00 on the 25th.
We estimate that it will take about an hour to do the move.

We are currently experiencing some problem with the /pfs/nobackup file system on Abisko.
To get it back into working order we are forced to reboot some of the nodes, thereby killing the jobs on them (the jobs would fail anyway due to the problem)
We apologize for this and are working as fast as we can to get it back in working order.
*UPDATE 2014-03-21 18:33*
/pfs/nobackup is now (hopefully) back in working order on Abisko
