The idea has been around and so has software and not just from Sandia. The Scyld cluster software costs $2 for non-commercial use and is widely used. The technology is advancing very quickly, for instance Avalon at LANL came in 113 on the Top500 in 11/98 at 48 gigaflops. Systems with say 64 Athlon processors and doing roughly 75-80 gigaflops are available pre-built or can be and are constructed by a wide variety of universities and corporations (check out the Beowulf list to get an idea of the range of applications and the number of large clusters out there). There are many application of cypherpunk-interest for this sort of cheap computing power. Unfortunately crypto probably isn't one of them. It is far easier to increase the size of the key than to scale up the processing power in a meaningful way. Until far more efficient factoring algorithms are found the math will insure this remains the case.
Never said it was. 50? try 512.
You never know what might come from putting that kind of computational power in the hands of people here. Create, break, do whatever you want.
The technology is potentially revolutionary in many areas of interest to cypherpunks but factoring large numbers is so hard and it is so easy to increase the size of keys that crypto will easily stay ahead of the Beowulf technology. Now if someone had a working quantum computer that might be a different story. Jim Windle Join 18 million Eudora users by signing up for a free Eudora Web-Mail account at http://www.eudoramail.com

Yep. I just thought people might appreciate the link. I'd be interested to hear from anyone actually running the Cplant to see how it stacks up with the other programs out there.. I'll save it for another list, I suppose.

My phrase "interesting possibilities for cryptographic applications" wasn't by any means referring to factoring alone.

I wouldn't rule anything out just yet! Fascinating stuff. And as for the problem of it being hard to round up enough Pentiums, plenty of businesses upgrading their systems might be willing to donate their old boxes to your "good cause" if you find a convincing way to explain what you're trying to do. I've been toying with the idea myself on and off for awhile: the idea of having your own supercomputer in your basement that you put together yourself out of next-to-nothing is just so appealing! Oh well, thanks for the links. ~Faustine.
