old news

As some of you may have noticed the /pfs/nobackup filesystem is chock full. As a side effect of that the batch systems are holding off on starting new jobs.

This is due to a lot of users keeping old files in the filesystem.

Please note that even if you are using a smaller amount than your quota limit you are obliged to remove old files and strive to keep your filesystem usage as small as possible.

The nodes in the bigmem partition are currently being upgraded to new CPUs.
They will be under testing until 2014-02-04.

Thus no jobs will run in the bigmem partition until then.

*UPDATE 2014-02-05 09:20*
The bigmem partition is now back in production

We have updated the information on Gromacs with new submit file examples.
We stringly suggest that users take a look at them for increased efficiency.

Octave 3.6.4 has been installed on Abisko. It is loaded like this:

module load octave

If you do not load the module, the version of octave will be 3.2.4, which is the version included with the operating system.

The final system to be upgraded is the batch system server.

To do this we need to have the system completely stopped so as to not risk any jobs failing.
We have therefor created a reservation on the whole batch system starting on Monday 2013-12-16 08:00, which means that no jobs are allowed to be running past that point.

I.e. no jobs will be allowed to start unless they have a runtime which guarantees that thay have finished before that time.

The normal login node for Abisko has now been updated and opened for login.

The temporary name abisko-precise.hpc2n.umu.se has been deleted and the node will be converted to a compute node.

We have now started migrating the first 2 racks of nodes to Ubuntu Precise.

The old login node will be stopped after lunch today (2013-11-22) and upgraded.
During the upgrade of the login node we recommend that you use the
abisko-precise.hpc2n.umu.se login node for accessing your files and rebuilding of any programs using new modules and compilers.

As mentioned previously all information is available at /resources/hardware/abisko/os-upgrade

We have suffered an extended power failure early in the morning (2013-11-20) and HPC2N resources may have limited or no availability until everything is up and running again.

Update 09:30
Power is now restored.

Update 11:00
Unfortunately the network in the building is still not working properly so everything should still be considered down.

Update 13:55
Power and network are now classified stable again, and login access and clusters are back online.
