The first scalable multi-threaded Pi-benchmark for multi-core systems...



How fast can your computer compute Pi?



y-cruncher is a program that can compute Pi and other constants to trillions of digits.

It is the first of its kind that is multi-threaded and scalable to multi-core systems. Ever since its launch in 2009, it has become a common benchmarking and stress-testing application for overclockers and hardware enthusiasts.



y-cruncher has been used to set several world records for the most digits of Pi ever computed.105 trillion digits - February 2024 (Jordan Ranous, Kevin O’Brien, and Brian Beeler - StorageReview)
100 trillion digits - June 2022 (Emma Haruka Iwao)
62.8 trillion digits - August 2021 (UAS Grisons)
50 trillion digits - January 2020 (Timothy Mullican)
31.4 trillion digits - January 2019 (Emma Haruka Iwao)
22.4 trillion digits - November 2016 (Peter Trueb)
13.3 trillion digits - October 2014 (Sandon Van Ness "houkouonchi")
12.1 trillion digits - December 2013 (Shigeru Kondo)
10 trillion digits - October 2011 (Shigeru Kondo)
5 trillion digits - August 2010 (Shigeru Kondo)
