Thanks John,
I appreciate your response. It is what I thought but I wasn't quite sure. I
looked at MPICH2 for Windows and it does have two techniques with tradeoffs as
you mentioned...I hope that you do decide to open up things a little more and
allow other job schedulers and MPI stacks acce

I doubt it. while gaming consoles are admirably commoditized (actually
sold at a loss in some cases), they're designed with constraints different

Now that's weird:
* it's an offload engine
* it claims to "lower your ping" i.e. help short messages
On a related, yet more serious note:
Would something like this:

Could the onboard Linux system help to prioritize MPI traffic? Or is
it kind of pointless when you can just buy extra NICs for $10 -
instead of $200 for one of these babie

MPICH is BSD licensed. Quite a few closed source MPIs are based on it.

Regarding the 'borgification' of MPI on Windowsthere is an opening
for them to do this. MPI did not define how you start the tasks when
you launch a parallel jobit left that up to the MPI implementation.
