PrimeGrid
Overview
PrimeGrid is a distributed computing project for searching for prime numbers of world-record size. It makes use of the Berkeley Open Infrastructure for Network Computing (BOINC) platform. As of August 2010, there are about 5,000 active participants (on about 11,500 host computers) from 89 countries, reporting about 65 teraflops.
