January 2013 quarterly maintenance is complete

This entry was posted by on Wednesday, 16 January, 2013 at

Greetings!

We have completed our quarterly maintenance activities.  Head nodes are online again and available for use, queued up jobs have been released, and the scheduler is awaiting new submissions.

Our RedHat 6 clusters have received system software updates.  Please keep an eye on your jobs to verify everything is operating correctly.

Our Panasas scratch storage has received another round of updates.  Preliminary testing indicates that we should have a resolution to our crashes, but the quota system is known to be broken.  As advised by Panasas, we have disabled quotas on scratch.  Please do your best to stay below the 20TB threshold.  We will be monitoring usage and know where you live.  🙂

We have a new license server providing checkouts of the Portland Group and Intel compilers, Matlab DCS, the Allinea DDT debugger and Lumerical.  Please let us know if you have problems accessing this software.  The old server is still running and we will be monitoring it for a short while for extraneous activity.

More nodes from Joe and the FoRCE have been converted from RHEL5 to RHEL6.  If you are still using the RHEL5 side of the world, please prioritize a transition to RHEL6.  We stand ready to assist you with this transition.

Finally, our new configuration system has been deployed in prototype mode.  We will use this to gather operational information and other data that will facilitate a full transition to this system in a future maintenance day.

As usual, please let us know (via email to pace-support@oit.gatech.edu) if you encounter any issues.

Happy Computing!
