PrimeGrid is a
distributed computing project for searching forprime number s of world-record size. It makes use of theBerkeley Open Infrastructure for Network Computing (BOINC) platform.Primegrid worked with the
Twin Prime Search to find record-size twin primes that are approximately 58700 digits long. The project ended when a new twin of that size was discovered onJanuary 15 ,2007 (sieved by Twin Prime Search and tested by PrimeGrid). A project to search for twin primes that are just above 100000 digits long is in progress.As of
January 4 ,2008 , the project has discovered the three largest Woodall primes known to date. [ [http://primes.utm.edu/top20/page.php?id=7 The Prime Pages; The Top Twenty: Woodall Primes] ] The largest of these, 3752948*23752948-1, is the firstmega prime discovered that is also a Woodall prime and is 1129757 digits long. It was discovered onDecember 21 ,2007 by Matthew Thompson using theLLR program. [ [http://www.primegrid.com/ "PrimeGrid" website] ] The search for an even bigger Woodall prime continues.PrimeGrid is also running a search for
Cullen prime numbers, helping3*2^n-1 Search project search for primes, and sieving forPrime Sierpinski Project .References
