The numbers were kindly donated by Timothy Mullican, former world record holder. In 2020, we updated the Pi API to return 50 trillion digits, and added Machine Learning models to generate even better Pi music. We also made the source code available on GitHub. In the same year, Sara calculated 64 million digits of π using Cloud Functions (2nd gen), and Emma rebuilt the API with Cloud Functions and the demos with React. And for more on the history of calculating pi, check out this post on The Keyword. Check out the official blog for more details about the technical details and architecture of the calculation. In 2022, Emma Haruka Iwao, Ben Bleything, Sara Ford, and Steve McGhee together calculated 100 trillion decimals of pi. Since 2015, different members of the team worked on different Pi Day demos! We are part of the Google Cloud Platform Developer Advocacy team. Near full utilization of a 96-cores & 1.4TB of RAM n1-megamem-96 instance on /C6JxMHrrzj- Ray Tsang MaWho are We? Edit We also calculated 1 trillion digits of Pi using a 96-core 14TB n1-megamem-96 machine. Happy #PiDay! We just calculated 750-billion digits of Pi calculation in 10 hours (compared to 2-days it took in 2017) using something we'll announce soon on Stayed tuned! #PiDay2018 /lFfSv63EzL- Ray Tsang March 14, 2018 In 2018, we were able to recalculate 750 billion digits in just 10 hours! Sometimes, you just need a big honkin' VM /WUtLIhW4bs- Greg Wilson March 5, 2017Īt its peak CPU utilization, it consumed all 64 cores, and 5+TB of SSD storage.Ĭonsumed all 64 cores on a vm, of 8x375GB Local SSD & using 382GB of 416GB RAM for some serious computation /Fzptt1nDCw- Ray Tsang March 6, 2017 We used a 64-core instance, with 416GB of RAM, and tons of Local SSD + Persistent SSD. In 2019, Emma Haruka Iwao broke the Pi digits world record by computing 31,415,926,535,897 digits of Pi using Google Cloud Platform! Learn more details from Emma’s Calculating a record-breaking 31.4 trillion digits blog, and Alex Yee (creator of y-cruncher)’s Google Cloud Topples the Pi record article.īack in 2017, we used y-cruncher to calculate 750 billion digits of Pi on Google Compute Engine. In 2022, Sara Ford and Ben Bleything calculated 64 million digits of π using Cloud Functions (2nd gen). We have the entire source code published on GitHub including Terraform scripts that we use to provision the infrastructure. The frontend code is developed in TypeScript and React.įinally, this site is hosted on Firebase Hosting, which not only automatically serves the static content via a CDN, it also automatically provisions a SSL certificate for the custom domain! The authorative DNS servers are provided by Cloud DNS. The API endpoint, api.pi.delivery is exposed via a Global HTTP(s) Load Balancer. We have the same function deployed in three regions (US, Belgium, Japan) that fetches digits from a Cloud Storage bucket in the US multi-region. We developed the REST API in Go and running the program in Cloud Functions (2nd gen). With 100 trillion digits and playing at 314 BPM, it'll play for 605,516 years! In this demo, we use each digit for and reuse the last digit for, and use Piano Genie to map to the next logical note for great sounding Pi. ![]() Piano Genie is an neural network model that allows you to play a note from 1 to 8, and intelligently map it to a great sounding piano performance. ![]() What does Pi sound like? Each Pi digit is converted to a musical note so you can get to know Pi via music! It is managed by volunteers of the Google Cloud Developer Advocacy team and may become unavailable without notice. This website is not an official Google product. We’ve also published the entire source code of the demos and infrastructure, including Terraform scripts, on GitHub. To learn more about how this site works, check out the Serving the Pi section. This website serves pi and interactive demos that you can listen to or see pi with. We’ve also published the entire results on Cloud Storage so you can download the files (caution: they are really big). We’ve updated the API to serve all of the 100 trillion digits of pi. This is the second time we’ve used Google Cloud to calculate a record number of digits for the mathematical constant, tripling the number of digits in just three years after our world record with 31.4 trillion digits in 2019.Ĭheck out the official blog for more details about the technical details and architecture of the calculation. ![]() In March 2022, we calculated 100 trillion digits of pi using Compute Engine.
