Prime95, also distributed as the command-line utility mprime for FreeBSD and Linux, is a freeware application written by George Woltman. It is the official client of the Great Internet Mersenne Prime Search (GIMPS), a volunteer computing project dedicated to searching for Mersenne primes. It is also used in overclocking to test for system ...
The proof files are generated while the Fermat primality test is in progress. These proofs, together with an error-checking algorithm devised by Robert Gerbicz, provide a complete confidence in the correctness of the test result and eliminate the need for double checks. First-time Lucas-Lehmer tests were deprecated in April 2021. [15]
New Mersenne primes are found using the Lucas–Lehmer test (LLT), a primality test for Mersenne primes that is efficient for binary computers. [ 2 ] The displayed ranks are among indices currently known as of 2022 [update] ; while unlikely, ranks may change if smaller ones are discovered.
George Woltman (born November 10, 1957) is the founder of the Great Internet Mersenne Prime Search (GIMPS), a distributed computing project researching Mersenne prime numbers using his software Prime95. He graduated from the Massachusetts Institute of Technology (MIT) with a degree in computer science. He lives in North Carolina.
The Lucas–Lehmer test works as follows. Let M p = 2 p − 1 be the Mersenne number to test with p an odd prime.The primality of p can be efficiently checked with a simple algorithm like trial division since p is exponentially smaller than M p.
In March 2007, Futuremark launched a website specialising in news and reviews of PC games, called YouGamers. [6] In January 2008, Futuremark announced the formation of the Futuremark Games Studio. [7] In August 2008, at the Leipzig Games Convention, Futuremark Games Studio announced details of its first game, Shattered Horizon. [8]
SPECfp is a computer benchmark designed to test the floating-point performance of a computer. It is managed by the Standard Performance Evaluation Corporation. SPECfp is the floating-point performance testing component of the SPEC CPU testing suit. The first standard SPECfp was released in 1989 [1] as SPECfp89. Later it was replaced by SPECfp92 ...
The Standard Performance Evaluation Corporation (SPEC) is a non-profit consortium that establishes and maintains standardized benchmarks and performance evaluation tools for new generations of computing systems.
