The concept of prime numbers (prime numbers) should still be remembered, so do you know the Mason Mersenne (Marin)?

This is the French mathematician, Ma Lan

Before that, a total of 49 Mason prime numbers were found. However, from 1997 to now, all the new Mason prime numbers were discovered by the Internet Mason prime search (GIMPS) distributed computing project. 15 have been discovered before.


After confirmation, in December 26, 2017, Jonathan Pac, a 51 year old federal express and an electrical engineer in Tennessee, found fiftieth Mason primes, 2.Seventy-seven million two hundred and thirty-two thousand nine hundred and seventeen-1, that is, 1 of the 77232917 times of 2.

It is a 23249425 digit number.In 2016 January, Mason found forty-ninth more primes to 1 million bit, can be filled with 9000 pages, 1 seconds to write 1 inches (2.54 cm) long to run for 54 days, the numbers of up to 37 miles (59.5 kilometers), more than forty-ninth long 3 miles (4.8 kilometers).

Jonathan Pac has joined the GIMPS project to find prime Mason more than 14 years, the use of their own a Core i5-6600 computer, has been running for six days, to get this important discovery, and by four people in five different platforms using four different algorithms is verified:

Aaron blosser, Intel Xeon server, Prime95, 37 hours.

David Stanfill, AMD RX Vega 64 graphics card, gpuOwL, 34 hours.

Andreas Hoglund, NVIDIA Titan Black graphics card, CUDALucas, 73 hours; Amazon AWS, Mlucas, 65 hours.

Ernst Mayer, 32 core Xeon server, Mlucas, 82 hours.

Jonathan Pac won a $30 thousand bonus for this. Then if the first to find the first more than 100 million figures of the prime number of Mason, will get a $150 thousand bonus! 1 billion figures will be rewarded for $250 thousand!
