Jordan Ranous from StorageReview has just flexed a system that matched Google's 100 trillion digit world record in just 59 days. just AVX2 - no wider execution units needed. Expect to see Zen 4 gaining up to 20% speedup with AVX512 vs.

Nevertheless, it doesn't make a whole lot of sense to keep around hundreds of thousands of lines of old code if turns out to be the better stress test. But with so much stuff being rewritten, there's no telling how this will change. In other words, it is one of the best memory testers out there. Despite not being designed for this purpose, y-cruncher's stress-test is notorious for its ability to expose memory instabilities that other (even dedicated) memory testing applications cannot. And it's unclear whether it can be fixed before it is no longer possible to keep using their old compiler.Ī big unknown is how stress-testing will be affected.
Specifically, there are unresolved toolchain issues where Intel is removing their old compiler while its replacement is still significantly worse. Nevertheless, the benchmarks above are not final and are subject to change. But since the new code has reached or exceeded performance parity for the chips I care about, this is a good stopping point for v0.8.1 pending testing and validation.
For example, swap-mode is still using the old implementations and will need to be revamped as well. Overall, there is still a lot of work to do. Stay tuned for a future blog about the algorithm. While it was the fastest thing in 2008, it unfortunately did not age very well. Yes, the Hybrid NTT that started the entire y-cruncher project is now gone. The loss of performance for the oldest processors is primarily due to the removal of the Hybrid NTT. Work actually began more than 3 years ago, but very little progress was made until this year where I'm on garden leave and therefore not working.Īs of today, enough has been done to get some preliminary in-memory benchmarks: Processor More than 400,000 lines of code will be touched. The implication of this will be performance gains on newer processors and regressions on older processors. Algorithms that are useful on modern processors are getting redesigned and rewritten from scratch while the rest will be completely removed from the codebase. In an effort to clean up and modernize the project, most of the large multiply algorithms are getting either refreshed or removed. Upcoming Changes for v0.8.x: (June 7, 2023).
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.
