Prime95
Prime95 is free Mersenne-prime search software for people who want to contribute computing work to GIMPS. It can also put a sustained workload across CPU cores to check processor and L1, L2, and L3 cache stability. For project tasks, Prime95 contacts PrimeNet for work; users can monitor computer progress and manage assignments remotely through the account’s CPUs page. Listed work includes PRP and Lucas-Lehmer tests, P-1 and ECM factoring, and trial factoring. Downloads include Windows, Linux, Mac OS X command-line, and FreeBSD builds. Administrators can choose a GUI-less Windows service build, which is intended for Windows Server experts. The source archive covers Windows, Linux, FreeBSD, and Mac OS X, though the code is described as non-portable. Version 30.3 introduced a dialog for limiting resource use. GIMPS participation is free and open internationally. The license permits indefinite free use on computers users own or are authorized to use, and provides the software as-is without warranty.
