Suitable use

Low latency parallel applications such as mpi jobs requiring up to 1GB/core, specify "-f opteron" with sqsub. For mpi or threaded jobs requiring upto 3GB/core memory and involving intensive local write activity of large size data sets to /tmp specify instead "-f xeon" with sqsub. Note that nodes 24-28 contain dual socket, quad core processors with hyper-threading enabled, yet appear as 16-way nodes even though their effective computing power is limited to 8 cores per node.
