Mlucas is a program for performing Lucas-Lehmer tests of prime-exponent Mersenne numbers, and Pépin tests of Fermat numbers. It is written by Ernst W. Mayer using C programming language and ARM assembly. It also includes an optional Python script for assignment management for the GIMPS project's PrimeNet server.
Mlucas is an open-source program and, unlike George Woltman's Prime95, does not impose prize-sharing rules, should a user be lucky as to find a new prime eligible for the monetary prize offered by the Electronic Frontier Foundation.
Mlucas includes optimizations for processors supporting AVX-512, AVX2, AVX, SSE2 or ARMv8 SIMD instruction sets.
As of June 2017, Mlucas v17.0 run only about 10% slower than Prime95 on powerful hardware.
The program was used to verify primes M38, M45, M46, M47, M48, M49, M50 and M51 at the times of their discovery.
