In these past 2 years of hiatus, I cleaned out my lab and retired a bunch of the older computers which were used to tune these binaries. A lot of the old binaries (00-x86, 04-P4P, 05-A64, 08-NHM, 11-SNB, 11-BD1), have been either removed or retuned for newer processors.I have yet to test if the latest TBB fixes the low CPU utilization issue from before. Compilers and libraries have been updated 2 years to the latest.Added some minor features and bug fixes for some new issues that arose on some very large computers.(3-5% improvement) This improvement should translate to Alder Lake and Sapphire Rapids. This significantly bigger system has produced a binary that is noticeably faster than the old one. The 18-CNL binary for Cannon Lake has gotten a facelift and is now retuned for an 8-core Tiger Lake laptop with 64GB of ram.For benchmarking, you may want to try both and see which one is faster for your specific system. The Zen 3 tunings generated by the superoptimizer aren't strictly better than Zen 2's tunings. A new binary for Zen 3: AMD graciously provided me a Zen3 system to do this, though the results are mixed.While I'm not officially back to working on y-cruncher, I am giving it some much needed updates. The project has been on hiatus for 2 years as I took a break for other things. 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).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.
