Finally, Serge Batalov ran Ernst Mayer's MLucas software on a 18-core server to verify the prime. Cooper is a professor at the University of Central Missouri. The primality proof took a month of computing on a PC with an Intel I7-4790 CPU. Cooper and the University of Central Missouri is the largest contributor of CPU time to the GIMPS project.The discovery is eligible for a ,000 GIMPS research discovery award. Cooper's computer found the record prime, the discovery would not have been possible without all the GIMPS volunteers that sifted through numerous non-prime candidates.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.It bests the previous record prime, also discovered by GIMPS, by 910,807 digits. If every second you were to write five digits to an inch then 54 days later you'd have a number stretching over 73 miles (118 km) -- almost 3 miles (5 km) longer than the previous record prime.Jonathan Pace is a 51 year old Electrical Engineer living in Germantown Tennessee.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?
To be thorough, the prime number was independently verified with four different programs running on various hardware configurations.
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.
With no new, smaller primes found, M(37156667) is officially the "45th Mersenne prime".
With no new, smaller primes found, M(32582657) is officially the "44th Mersenne prime".
Congratulations and thanks to all the GIMPS members that contributed their resources towards this milestone. The FFT assembly code has been optimized to use Intel's fused multiply-add instructions on Intel's Haswell CPUs (Core i3/i5/i7-4xxx models).The prime number, also known as M74207281, is calculated by multiplying together 74,207,281 twos then subtracting one.
