40th Mersenne Prime confirmation proves power of P2P
You count them in, you count them out again

EARLIER REPORTS that peer to peer software had discovered a 40th Mersenne Prime have been confirmed by the GIMPS pursuing the ultimate numbers.
The boffins have said the newly discovered Mersenne Prime is 220,996,011-1, or 2 to the 20,996,011th power minus 1.
Michael Shafer picked it up on the 17th November last, as a result of using prime 95 on his office computer.
And the discovery was verified by Guillermo Ballester Valor on November 30, using Glucas on a quad Itanium-II machine.
But that machine only used two of the four available processors. Glucas was three days faster than a Pentium 4 2.1GHz single CPU machine, the boffins report. [2.1GHz? Does Intel make that speed? Ed.]
Shafer is a chemical engineering student at Michigan State University. µ
