This certainly is interesting, but I think we would need to make the
runtime multi threaded before starting something this ambitious. With the
current crop of Duo and Quad machines available adding multi threading to
Icarus has been one my mind. The problem is finding the time to work on
it.

Much of Icarus is bit based, so FLOPs are not as important as for an
analog simulator. Though with those kind of numbers I'm sure they would be
more than fast enough ;-).

Thanks for the information,
