SUG@R Queue Policy

The following queue policy was implemented for SUG@R in June, 2008

The maximum number of CPUs available to all users system-wide is 816. The maximum possible number of CPUs in the commons queue is 752 and will usually be less due to special projects and system maintenance tasks.
The maximum number of cores (processors) allowed to be running at one time for any user is 32 under normal load regardless of how many jobs are in the queue or how many cores per job requested. This number will be increased to 128 automatically under light load. The maximum number of cores (processors) that may be requested in any one job is 8 and they must be within the same node (no MPI traffic between nodes).
