Hungabee Not Accepting Jobs - Aug. 21

The main Hungabee node - the UV1000 - has an issue with its batch scheduling software which is preventing any new jobs from being run.  As well, it may cause the loss of currently running jobs.  The UV100 node (for small jobs) is not affected.

The problem is being investigated.  If a quicker solution cannot be found, the UV1000 will be restarted after all currently running jobs are off the machine.  If the machine is restarted, it should become available again late tonight or early tomorrow.

October 16, 7:01am (central time): A brief power fluctuation at the University of Manitoba caused all compute nodes on Grex to reboot and all jobs were lost.

October 16, 7:33am (central time): Most compute nodes are online and we will enable job submission in the next hour or so.

October 16, 8:23am (central time): Grex is back in production.

We apologize for this inconvenience. Please contact if you have any questions or concerns.

August 13, 2012: Updating Torque System on Grex.

we are updating the Torque system on Grex. The queues will be temporarily disabled and you may face issues with the job submissions.

Sorry for the inconvenience.

Aug. 10, 2012 Checkers jobs lost

Torque on checkers oversubscribed most nodes when the queues were restarted yesterday - this required torque to be restarted at about 4:00 am.

All queued and running jobs were lost. Unmonitored jobs are being removed from nodes and the batch system will be monitored as jobs enter the queue.

We apologize for this inconvenience.
