Total number of slots consumed in long_excl.q (exclusive nodes) will be restricted to 320 slots on June 4, 2013

May 28, 2013

The long queue has had a per-user limit of 320 slots (or 40 8-core nodes) for several months.  The long_excl.q has not had a similar limit.   On June 4, a per-user 320 slot limit will be introduced on the exclusive nodes (or 20 16-core nodes).  This will ensure that a single user cannot consume too many resources simultaneously in the long queues.  For large calculations requiring a great deal of resources, the normal queues should be targeted (jobs < 12 hours), as there are no per-user slots limits on those queues.
