The discussion seems somewhat unknowing of the methods used to brute force
the DES key for this contest. Please visit http://www.distributed.net to
get an idea of how we accomplished this.

It is interesting because idle cycles were used on common hardware to
complete this project. The only software for this project, that wasn't a
background task, was the DOS client.

Actually, the MAC code ended up being the most optimized of all the
platforms in the contest. Now this may have just been a side effect of
having better PPC asm coders, but I think there is more to it than that.
