UCLA group discovers massive prime number with Windows XP


WindowsXP LOS ANGELES – Mathematicians at UCLA have discovered a 13-million-digit prime number, a long-sought milestone that makes them eligible for a $100,000 prize.

The group found the 46th known Mersenne prime last month on a network of 75 computers running Windows XP. The number was verified by a different computer system running a different algorithm.

"We’re delighted," said UCLA’s Edson Smith, the leader of the effort. "Now we’re looking for the next one, despite the odds."

Q.  When did the discovery occur?  What kind of computer was used?

A.  The UCLA Mersenne Prime was reported on August 23, 2008 on a computer named zeppelin.pic.ucla.edu, a Dell Optiplex 745 running Windows XP with an Intel Core 2 Duo E6600 CPU running at 2.4 GHz.  The name "zeppelin" was part of our Classic Rock Band series of computers.

Glad they weren’t using OS X or Linux.  I’m a PC. I rock Zeppelin.  Grin.

    XP was probably perfect for this application.  Short of a text based Linux distro XP has the lowest hardware fingerprint of any of the current OS’s.

    I’m not impressed until they use Vista.

    Or on Windows Server HPC running on the new Cray "desktop".  Co’mon, admit it… how many of you went to the Cray site and config’d out a Cray to see how high you could get the price?  I hit 6 digits without even trying…. :-)

    I sure as hell did!!!
