<div>Well that's fair of course, I should have said that 5GHz is an unachiveable upper bound for a sufficiently distributable application. If I wanted to add some huge number of integers, which can be generated by some simple formula in ranges at each node, then 10 500MHz machines generating ranges and then computing subtotals would be almost as fast as one 5GHz machine, but for any real apps we would not see such a gain. I'm sure I"m overoptimistic about the "embarassing parallelism" of my own app, but pretty much it's pretty embarassing I'm pretty sure :-) Got's to see.
