Knowing more digits of pi isn't particularly important for mathematics. It is twice the previous record of 31.4 trillion set by Google in 2019. On August 5, 2021, researchers from the University of Applied Sciences of the Grisons in Switzerland announced that they had set a new world record by calculating the famous number to its first 62.8 trillion decimal places! This is over 12 trillion more decimal places than the current record of 50 trillion set by Timothy Mullican in 2020. While individuals attempt to break records by memorizing pi's decimal points, scientists strive to find its most accurate value using new algorithms and powerful computers. Instead, it is infinitely long and never forms a repeating pattern. This means it can't be written as a fraction. The numerical constant - defined as the ratio of the circumference of a circle to its diameter- is recognized by most as 3.14.

Reaching The Unreachable - Pi Squared And Catalan's Constant Yahoo! Gets to the 2 Quadrillionth bit of Pi - it's zero I’ll just keep counting.Ī bigger piece of the pi: Finding the 100-trillionth digitĥ Trillion Digits of Pi - New World RecordĦ0 trillionth binary digit of pi-squared calculated We could still see another fundamental shift that keeps the momentum going. Plus, we don't see an end to the evolution of computing. There's no end to π, it’s a transcendental number, meaning it can't be written as a finite polynomial. She also hints that she's likely to re-try:īack when I hit that record in 2019 - and again now - many people asked "what's next?" And I’m happy to say that the scientific community just keeps counting. I used the same tools and techniques as I did in 2019, but I was able to hit the new number more quickly thanks to Google Cloud’s infrastructure improvements in compute, storage and networking. Referring to her latest success, Iwoa noted: This infographic shows how the number of digits and data processed increased while the calculation time shrank between the two occasions. This list of Pi milestones comes from the y-cruncher website:Įmma Haruka Iwoa initially used y-cruncher when she first broke the digits of pi world record in 2019 with 31.4 trillion digits, see Google Smashes Pi Record For Pi Day 2019. The following year Shigeru Kondo doubled the number of digits, to 10 trillion and this latest record, which is in the process of being evaluated as a Guinness World Record, takes us to the next order of magnitude. It was a fairly upmarket machine for the time with 12 physical cores and 24 hyperthreads, 96GBytes of Ram and 40TByes of disk storage. What we found remarkable then was that this had been achieved using nothing but a desktop computer.
Yee & Shigeru Kondo computed pi to 5 trillion digits. Back in August 2010 we reported on the algorithm's first breakthough when Alexander J.
The first scalable multi-threaded Pi-benchmark for multi-core systemsĭates from 2009 and has been breaking records ever since.
The y-cruncher algorithm, which originated in "a high-school project that went a little too far" and is described as: Total I/O: 43.5 PB read, 38.5 PB written, 82 PB total.Total storage size: 663 TB available, 515 TB used.Total elapsed time: 157 days, 23 hours, 31 minutes and 7.651 seconds.Compute node: n2-highmem-128 with 128 vCPUs and 864 GB RAM.Program: y-cruncher v0.7.8, by Alexander J.The calculation required 82,000 terraabytes of data to be processed and its vital statistics are provided in this overview from the Google Cloud blog: If the sequence leading up to the 0 was read out loud at the rate of 1 digit per second, the feat would require 3.17 million years.
The task took until Maand led to the discovery that the 100-trillionth decimal place of pi is 0. New Record From Google - 100 Trillion Digits Of PiĮmma Haruka Iwao, a Developer Advocate at Google Cloud, started a calculation to compute pi to 100 Trillion digits on Google Cloud from her home office on October 14 2021.
