"Berkeley Open Infrastructure for Network Computing (BOINC) is a software platform for projects, like distributed.net and SETI@home, that use millions of volunteer computers as a parallel supercomputer." Source code is available for the platform, and interested C++ developers are encouraged to help develop the platform code. Information about BOINC is available in the following langauges (through links at the project website): Chinese, Estonian, Danish, French, German, Russian, Spanish.
BOINC is currently being developed and tested on Windows, Linux, UNIX, and Mac OSX platforms. CPU platform requirements may vary among project clients using BOINC. The first public application based on BOINC will be released in January, 2004. Projects planning to use BOINC are: Astropulse, SETI@home, Folding@Home, climateprediction.net, and an upcoming project by the University of Maryland's Center for Bioinformatics and Computational Biology to analyze DNA sequence data to investigate molecular evolution, particularly of bacteria that cause tuberculosis and leprosy"
