I've been asked to see if there's a way to configure
SGE so that jobs are scheduled to run on in the
following order of preference:

1) Cores on the same multi-core processor
2) Cores on the same multi-processor node
3) Everything else

The purpose of this is to minimize latency in
a 28 node cluster that uses a Gb switch to connect the
nodes. Each node has 2 dual-core Opteron 280s.
We're currently using SGE 6.0.
