The PRPnet server is an application that manages a list of numbers for which the primality is unknown. PRPNet clients connect to the server to get one or more candidates on which a primality test is needed. The server ensures that only one client at a time is testing any particular candidate and then captures the results of the test and records that information in a MySQL or PostgreSQL database.

PRPNet collects numerous stats for the clients that connect and clients can associate themselves with teams. It has a number of webpages that can be used to show current progress and statistics. It also has the ability to send e-mail when a new prime is found.

Although PRPNet works well for home users with multiple cores or multiple machines, it does scale well up to a few hundred users. PrimeGrid runs most of its smaller projects on PRPNet..

PRPNet also has the ability to test for Wieferich and Wall-Sun-Sun primes. The client can run an OpenCL application for maximum throughput.
