The Great Internet Mersenne Prime Search, or GIMPS, is a collaborative project of volunteers, who use Prime 95 and MPrime, special open source software that can be downloaded from the Internet for free, in order to search for 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.

This project has been rather successful: it has found a total of 7 Mersenne primes, each of which was the largest known prime at the time of discovery. The largest known prime as of May 2004, is 224,036,583 − 1. This prime was discovered on May 15, 2004 by Josh Findley. Refer to the article on Mersenne primes numbers for the complete list of GIMPS successes.

As of May 2004, GIMPS has a sustained throughput of approximately 14 teraflops, earning the GIMPS virtual computerIn general terms, a virtual machine in computer science is software that creates an environment between the computer platform and the end user in which the end user can operate software.

Technically the GIMPS software is not open source, since it has a restriction which most open source/ free softwareThis article refers to free software as defined by the Free Software Foundation. For software available free of charge, see Freeware. The term free software refers to software which, once obtained, can be used, copied, studied, modified and redistributed. groups find unacceptable—users must abide by the prize distribution terms. This restriction will become meaningless when the EFF prizes are claimed.
