I don't think that's a good guess. Not only are conventional cpus
getting wider over time, but the whole point of EPIC and VLIW in
general is that they potentially go _really_ wide. And most scientific
codes can use lots of functional units.

PNL's codes require 64-bit addressing. I don't think anyone was
willing to bid AMD's Hammer, although it was a possibility.
The problem with pricing this bid are that it's all forward-priced. HP
is committing to delivering Madison processors when McKinley isn't
even formally released. That means risk, and that means you need to
subtract off $$ to cover that risk. That skews all of your analysis.
BTW, the interconnect is next generation Quadrics. I've never seen any
specs for it, nor pricing.
