it looks like 'hpc ethernet' is really just a classic cray memory network design with hop-by-hop retransmission and rigid flow control. so really a port can fall back to supporting ethernet? maybe it would have been easier to just put an adapter in there? just wondering what the real meat is. i do think convergence with non-supercomputer systems is a great idea and should help quite a bit with NRE
