This is possible, but not really recommended.  There's no real way to
ensure a certain part of a job gets run on a certain node, so you have
to assume all nodes are equal.  But if you do this and have unequal
nodes, you'll find your jobs processing at the rate of the slowest
nodes.

I'd recommend just putting the 500's in the cluster, and if you really
need the extra power, put the 100's into a seperate cluster.
