Projects

	PrimeGrid Search for Twin, Proth, Cullen, Woodall, 321, and Sierpinski primes. This project requires a BOINC client. Project Homepage | Statistics
	RieselSieve Attempt to solve the Riesel problem: Finding the smallest k such that k·2n-1 is composite for all natural numbers n. This project requires a BOINC client. Project Homepage | Statistics
	Seventeen or Bust Attempt to prove that 78,557 is the smallest Sierpinksi number, a number k for which k·2n+1 is composite for all natural numbers n. Of the 17 initial Sierpinski numbers, 6 remain to be proven to be prime for some value of n. Project Homepage | Statistics
	Great Internet Mersenne Prime Search Search for primes of the form 2n-1. These primes constitute many of the largest known primes in mathematics, the largest of which contains nearly 13 million digits. Project Homepage | Statistics

PrimeGrid: AP26 application available for Solaris -- July 1, 2009
We have released a version of AP26 application for 64bit Solaris (on AMD x86_64 or Intel EM64T CPUs, platform name x86_64-pc-solaris). This is our first application for this platform, which also makes AP26 an application that runs on the most platforms. Thanks to Gerrit Slomma for building the app! Psst... the PS3 version is coming ;)

PrimeGrid: New Top Host! -- June 19, 2009
Congratulations to Worldwide Center of Mathematics, owner of the new top host at PrimeGrid. While this position has changed many times in the past, what makes this occasion unique is that this is the first time the top host is a Mac!!!

PrimeGrid: GIMPS does it again!!! -- June 13, 2009
Congratulations to The Great Internet Mersenne Prime Search (GIMPS)! On April 12th, Odd Magnar Strindmo of Norway discovered the 47th known Mersenne prime, 2^42,643,801-1. It is the second largest known prime at 12,837,064 digits, only 141,125 digits smaller than the Mersenne prime found last August. The prime was independently verified June 12th.For more information, please visit the GIMPS site. Again, congratulations!!!

PrimeGrid: Record APs Found -- May 29, 2009
PrimeGrid has found two new records for AP22 and AP23 (Arithmetic Progression of 22 primes and 23 primes respectively). They are the smallest known starts for each of their classifications.The finders are Jacek Kotnowski (sosnahojna - team BOINC@Poland) of Poland for the AP22 record and Eric Markle (Nikodemus - team BOINCstats) of the United States for the AP23 record. They were found in the AP26 Search. For more details on these finds and the AP26 search, please see these forum posts - AP22, AP23.
