'''GIMPS'''(Great Internet Mersenne Prime Search)는 [[인터넷]]을 통해 무료로 다운로드할 수 있는 [[Prime95]]과 [[MPrime]]과 같은 특별한 [[소프트웨어]]를 사용하여 [[메르센 소수]]를 찾는 사람들의 공동 프로젝트이다.

<!--
모든 소수는 M<sub>''n''</sub>의 형태로 표시되며, 여기서 ''n''은 지수이다. 소수 자체는 2<sup>''n''</sup> - 1 이며, 아래 표의 첫 번째 소수는 2<sup>32582657</sup> - 1 이다.

''', or '''GIMPS''', is a collaborative project of volunteers, who use [[Prime95]] and [[MPrime]], special [[software]] that can be downloaded from the [[Internet]] for free, in order to search for [[Mersenne prime|Mersenne prime numbers]]. The project was founded and the prime testing software was written by [[George Woltman]]. [[Scott Kurowski]] wrote the PrimeNet [[server]] that supports the research to demonstrate [[Entropia]] distributed computing software, a company he founded in 1997.

숫자 M<sub>32582657</sub>은 9,808,358 자릿수를 갖는다. 이 숫자의 크기를 시각적으로 표현하기 위하여, 표준적인 워드 프로세서 레이아웃(1 페이지에 50 라인, 1라인에 75자리 숫자)에 2,616 페이지가 필요하다.
This project has been rather successful: it has already found a total of 8 Mersenne [[prime number|primes]], each of which was the largest known prime at the time of discovery. The largest known prime [[as of 2005|as of March 2005]] is 2<sup>25,964,951</sup> − 1. This prime was discovered on [[February 18]], [[2005]]. Refer to the article on [[Mersenne prime]] numbers for the complete list of GIMPS successes.
As of June 2005, GIMPS has a sustained throughput of approximately 17 [[FLOPS|TFLOPS]], earning the GIMPS [[virtual machine|virtual computer]] a firm place among the most powerful [[supercomputer]]s in the world.
Although the GIMPS software has its source code available, technically it is not [[open source]], since it has a restriction which most open source/[[free software]] groups find unacceptable – users must abide by the prize distribution terms. This restriction will become meaningless when the [[Electronic Frontier Foundation|EFF]] prizes are claimed.
For open source alternatives, [ftp://ftp.oxixares.com/pub/glucas/snapshots Glucas] and [ftp://hogranch.com/pub/mayer/src/C/ Mlucas] are both licensed under the GPL.
