And using that, I'm able to produce a Zen4-optimized binary - well ahead of launch and in time for the hardware reviewers to pick up. You know what that means - a new y-cruncher binary for it!ĪMD has graciously provided me a pre-release sample of their Ryzen 9 7950X. Zen4 is set to be AMD's first processor to support AVX512. So if you're a SIMD programmer or just curious about architecture in general, this might be worth a read. Now that the embargos have lifted, I have published my breakdown of Zen4's AVX512 over on Mersenneforum.

5 trillion digits - August 2010 (Shigeru Kondo).

10 trillion digits - October 2011 (Shigeru Kondo).

12.1 trillion digits - December 2013 (Shigeru Kondo).

13.3 trillion digits - October 2014 (Sandon Van Ness 'houkouonchi').22.4 trillion digits - November 2016 (Peter Trueb).

31.4 trillion digits - January 2019 (Emma Haruka Iwao).

50 trillion digits - January 2020 (Timothy Mullican).

62.8 trillion digits - August 2021 (UAS Grisons).

100 trillion digits - June 2022 (Emma Haruka Iwao).

Y-cruncher has been used to set several world records for the most digits of Pi ever computed. Ever since its launch in 2009, it has become a common benchmarking and stress-testing application for overclockers and hardware enthusiasts. It is the first of its kind that is multi-threaded and scalable to multi-core systems.

Y-cruncher is a program that can compute Pi and other constants to trillions of digits. The first scalable multi-threaded Pi-benchmark for multi-core systems.
