Hi all,
So this is 4 cores sharing one ethernet connection?
perhaps the two Gigabit NICs were bundled somehow. But I guess this
doesn't work out-of-the-box&plug'n'play. And latency and not bandwidth
may be limiting in this case.
With such a setup you will never get good scaling.
You need something like an Infiniband network.
Or check:

Haven't tried it yet but sounds good!
