1. Introduction

The Great Internet Mersenne Prime Search is one of the very first distributed search internet projects. Since 1996 thousends of volunteers with tenthousends of CPU's are hunting for world record primes. As of April 2006, GIMPS is holding the 8 largest Mersenne prime numbers and the 4 biggest primes at all.

A Mersenne prime is a prime of the form Mp = 2p - 1. It is easy to see that the exponent p necessarily has to be prime. The residue of the Lucas-Lehmer Test gives definite information whether Mp is prime or composite. Factors of the Mersenne number Mp must have the form 2 k p + 1. The workflow choosen at the GIMPS project is: Personally, I am very proud to have been one of the very first participants in 1996 to join this project. In the late 90's I had up to 17 CPU's running while at the moment I try to keep an average of 2000 P90 CPU hrs/day on 3-4 CPU's. This gives me a rank of around 250 with some 100 P90 CPU years.
