Andrew,
You also need to state what *size* cluster you are targeting.
Some interconnects can provide hardware broadcast and do adaptive routing -
features which only start to show significant application speedup at larger job
sizes.
caveat: slightly biased view - I work for a vendor

Anyone here using it?
