In recognition of the individual discoverer, the software authors, the GIMPS project leaders, and every GIMPS participant's contribution, credit for the new prime goes to "Jonathan Pace, George Woltman, Scott Kurowski, Aaron Blosser, et al.".Could you be the next lucky volunteer to discover a brand new Mersenne Prime?

Volunteers download a free program to search for these primes with a cash award offered to anyone lucky enough to find a new prime. Chris Caldwell maintains an authoritative web site on the largest known primes as well an excellent history of Mersenne primes. Cooper's computer reported the prime to the server on September 17, 2015.

However, a bug prevented the email notification from being sent.

Haswell users should see a decent performance increase.

Sandy Bridge and Ivy Bridge users may also see a small speed boost due to some memory bandwidth optimizations.

GIMPS founder George Woltman, Prime Net creator Scott Kurowski, Primenet administrator Aaron Blosser, thank and congratulate all the GIMPS members that made this discovery possible.

To recognize all those that contributed to this discovery, official credit goes to Cooper, Woltman, Kurowski, Blosser, et al.While prime numbers are important for cryptography, this prime is too large to currently be of practical value.However, the search itself does have several practical benefits.Thanks to all the GIMPS members that contributed their resources towards achieving this milestone.Join now to help GIMPS press onward to proving M(42643801) is the 46th Mersenne prime. Curtis Cooper, one of many thousands of GIMPS volunteers, used one of his university's computers to make the find.You'll need a reasonably modern PC and the free software at — In 2008, M(37156667) was discovered, and after 8 years GIMPS has finished checking and double-checking every smaller Mersenne number.
