>>Who knows .... You're certainly right, probably not a concern for normal people. I thought about specialy built hardware, dedicated only for this kind of nummerical crunching and with cheap processors (like 8051, strong arm - i don't know which is faster for numerical computations). 15 years ago a guy has built a computer with 128 very cheap processors, optimized only for computing the Mandelbrot set. Something like this. If this discussion will continue and if I'll find the spare time it will determine me to try such a construction :-))).

A Cray costs $5.5 Million, and IBM tied the processing speed with $150,000 worth of hardware.

Thanks for the info, it's knew for me. Yeah, it's the direction in which I've pointed. But I think there would be a better and cheaper solution, but extremely dedicated. The IBM demo is great, but you have a lot of overhead with the OS itself, with the network protocols and so on. "My" ideea was to build a "computer", without OS, programm it in assembler only for this one task, hacking of this one type of encryption.
