Welcome to the Great Internet Mersenne Prime Search!

To use this program you must agree to the terms and conditions,
prize rules, etc. at https://mersenne.org/legal/

The GIMPS web site is at https://mersenne.org
Help is available at https://mersenneforum.org

FILE LIST
---------

readme.txt	This file.
prime95.exe	The windows program to trial factor and primality test Mersenne numbers.
mprime		The Linux program to trial factor and primality test Mersenne numbers.
libgmp*		A library containing the GNU multi-precision math package.
libhwloc*	A library containing routines to analyze your hardware (cores, cache sizes, etc.)
libcurl*	A library containing routines to send and receive internet messages.
libcrypto*, libssl*	Libraries required by libcurl.
		On some OSes you may need to copy libraries to the system library directory.

WHAT IS THIS PROGRAM?
---------------------

This program is used to find Mersenne Prime numbers.  See
https://primes.utm.edu/mersenne/index.html for a good
description of Mersenne primes.  Mersenne numbers can be proved
composite (not prime) by either finding a factor or by running
a PRP (PRobable Prime) or Lucas-Lehmer primality test.
