MPrime is the name of the Linux and BSD software, written by George Woltman, that GIMPS, a distributed computing project researching Mersenne prime numbers, uses. It is entirely console based, with no requirement for X or any other graphical sub-system. MPrime is freely available in both binary[1] and source code[2] form.

There is also a Windows-based version called Prime95.

The software is principally designed to test primality of Mersenne numbers, but can also apply several integer factorization algorithms (Elliptic curve method, P minus 1,...) to any number of the form k bⁿ+c (as of v.24.6).

Although not what MPrime was specifically designed for, it is also very efficient and widely used to test system stability via a "torture test" of processor and system memory.

A system capable of sustaining more than 24 hours of MPrime "torture" is often referred to as "prime stable". Such a system is highly likely to be stable under all conditions.^{[citation needed]}
