system news

Due to an important test that was omitted during last weeks testing we need to rerun one final job on the whole system.

Abisko will be unavailable for normal batch jobs starting Monday 21th May.
We will then perform full system runs for the TOP500 numbers.
It is expected to take 3-4 days.

We apologize for the inconvenience this will be causing.

Due to unexpected hardware problems we need to extend the runs over the weekend.

The HPL runs are part of the final system delivery testing and is, besides generating a good TOP500 result, aimed at ironing out any remaning hardware problems and making sure the user community can run really large jobs on the system without problems.

We suffered an unexpected power failure in parts of Umeå and especially at the university.

We are working to get things back online again.

ETA sometime after 13:00

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 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.
