Berkeley Open Infrastructure for Network Computing. A framework developed by the original seti@home team at the University of California at Berkeley. BOINC is a framework for distributed computing that supports multiple distributed computing projects. Users run the BOINC client on their computers and it analyzes various data (from interstellar radio signals to protein structure in living cells) using idle CPU cycles.
I must borg all these computers for BOINC!
All of my computers are BOINCing.
