Wednesday, April 10, 2012 - U of Calgary air conditioner maintenance complete

UPDATE: The AC is back online and jobs scheduling has been resumed.

One of the AC units in the research data center is undergoing maintenance. We have stopped scheduling jobs to Lattice and Parallel so as to not increase the heat load. We expect the AC to be operational by 2PM MST. Scheduling will resume after the AC is back in operation.

March 26, 2013, 12:45 PM (PDT) UBC Chiller failure


We have suffered the chiller failure and as a result orcinus is down.

All running jobs were lost. We will try to restore the operations as soon as possible.




 March 26, 2013, 19:30 PM (PDT)


 Plant Operations were able to restore partial cooling. Since the cause of the failure is unknown and the chiller still has some 

  vital components off-line, the scheduling has been suspended.


We hope that the normal operations could resume tomorrow, 


                Wednesday, March 27


 Please, check your data and resubmit the lost computations.

 We are sorry for the interruption and all inconveniences.

Hermes/Nestor: decommissioning old GPFS filesystem Tuesday 19 February

At 10 a.m. PST on 19 February 2013 we will be decommissioning the old GPFS filesystem to release storage for other uses.  We migrated off of this filesystem to new storage during the outage of 7 February 2013.

We do not expect this work to affect the new filesystem, but we will be removing storage and components from an active GPFS cluster and so there is some potential risk to the home and scratch filesystem.  Please let us know if you experience or observe any unexpected or adverse behaviour.
