It should be noted that y-cruncher, that closed-source program, is responsible for every pi computation record since 2010 (back then the record was 2.7T digits). Traditionally these records were held by supercomputers, but it seems that pi computation is no longer a good way to benchmark or stress-test them [1], leaving only interested individuals in the scene. If pi computation were useful by its own, or there were a lot of people working towards records, we can expect multiple competitive pi computation programs where some of them are hopefully F/OSS. (The algorithm itself is not exactly secret anyway and big ideas are already in public, what makes y-cruncher special is its meticulous optimization.) But I don't see anything like that. There seem no actual demands for pi computation software, not just F/OSS. [1] http://numberworld.org/y-cruncher/faq.html#why_desktops http://numberworld.org/y-cruncher/faq.html#why_desktops
