LOL :) i think this is a good Computer for Mr Spock compute in time-travel at what... Greetings from Germany NRW Ulli S@h Berkeley's Staff Friends Club m7 © |

Each CPU runs at 667 Mhz, and may need 50000 seconds per WU. Divide by 131072 and you get 0.38 seconds per WU :o) Regards Hans |

It would do a single work unit in about 13 hours. The only thing that makes it so impressive is that it could do "many" work units at once. :) Also I think it would hit the max work units per host per day limit pretty quickly :) A member of The Knights Who Say NI!

And once more I'm going to remind all present that those PowerPC 440s can be cranked as high as 2.1GHz w/o major difficulaties - a 3x increase... Go Big Blue, Go! |
