[Beowulf] FTC and Intel

What I saw (in a recent Slashdot, which I ought to be able to find) was the
idea that an Intel compiler disables it's own highest levels of
optimizations if it detects that the host processor is not Intel. The
complaint is based on that I believe.

FWIW, I imagine that if an automobile engine detected poor octane in the
fuel, it might throttle down the maximum speed of the car; but if it did so
after detecting a competitor's brand of gasoline, it could be considered
anti-competitive. But of course IMNAL or however we announce we ain't
lawyers so CGS (cum grano salis).
