Open-source application for distributed discovery of prime numbers. The application is capable of looking up numbers from 2 to 263-1 - per project requirements.
It is an academic project. Implemented in pure C99, according to rules of UNIX programming. Therefore, it is POSIX compliant, and therefore it should work without problems in any modern distribution of Linux. Due to the fact that application depends on being launched simultaneously on many machines, portability is a requirement, not an option.
