The most disappointing part: It's done with a closed-source program. Just like almost all pi records in the past decades.
The authors of the programs refuse to open source and instead opt to just release free binaries. Their reasons are that their algorithms are secret.
I suspect they don't want their program forked and don't want someone to take credit for a computation done with their program. Surprisingly, it has worked so far.
- eddyschai 4y agoI found it pretty amazing the codebase that cracked 100T digits (and the previous records too) were started as a guys high school project.
- lifthrasiir 4y agoIt 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
