Abstract: Since 2005, PrimeGrid has grown from a small project factorising RSA numbers by brute force to one of the largest volunteer computing projects in the world. The project has discovered over 60 new million-digit primes, as well as record sized twin and Sophie Germain primes. This paper will present a history of the project, the algorithms and software used by PrimeGrid and how the BOINC distributed computing architecture is used to harness tens of thousands of computers. We also highlight some recent results from several current prime search sub-projects.
