Yes, it seems to scale quite linearly with the number of CPU's.
csm@sgi.com is running an SGI Origin2000 with 128 CPU's and 2GB of
RAM. He's benchmarked it at over 20 million keys/sec, but he can't
dedicate the whole machine to it (luckily for the rest of us ;-)).

Well... I guess I'll make this an open invite: anyone not already
affiliated with a team is more than welcome to join our little
grassroots effort at rsacrack@vex.net (http://www.vex.net/~rasmus/rsa/).
We've got everything from PPro200's down to a wee Sun 3/60 that takes
almost 2 days to complete a single keyblock, and we don't favour one
particular OS over another. :)
