Yawn. First we had the attack of the killer micros. Now we have the
attack of the commodity interconnects. Do these special interconnects
with fancy global memory justify their cost vs. InfiniBand + HPC
tweaks? Do you really think you're going to program these machines
with something other than MPI?

Make your bets, wait, see if you win.

ps. I am pleased to see that the new EXTOLL interconnect has a
non-RDMA short message system.

pps. Blekko launches November 1. Check out the /hpc slashtag.
