3/27/2023 0 Comments Calculate pi to trillion digitsGoogle has published the scripts it used over on GitHub for those interested in digging deeper into the code. Team DAViS of UAS Grisons, headed by Heiko Rölke and Thomas Keller, computed an additional 12.8 trillion digits of pi. ![]() Using y-cruncher v0.6. In this specific instance, it also demonstrates the capabilities of Google's Cloud infrastructure and the reliability it affords. The most accurate value of pi is 62,831,853,071,796 digits, and was achieved by University of Applied Sciences of the Grisons (Switzerland) in Chur, Switzerland, on 19 August 2021. A 20 trillion digit computation of Pi would need a lot of disk space. Why keep going at this point? As Iwao highlights, Pi calculations can be used as a measuring stick to chart the progress of processing power over time. All said and done, the tweaks made the program about twice as fast. They also created a program that runs y-cruncher with different parameters and automated much of the measurement. (History of π computation from ancient times through today)Įmma Haruka Iwao, a developer advocate at Google, said they used Terraform to set up and manage the cluster. To see how many digits of Pi we need to accurately calculate the circumference, let us consider two versions of Pi: PiShort 3.141593 (6 digits after the decimal place) PiLong 3. The program ran for a total of 157 days, 23 hours, 31 minutes and 7.651 seconds, utilizing 43.5 PB of reads and 38.5 PB of writes in the process. ![]() For comparison, the 2019 calculation had just 16 Gbps of egress bandwidth. This time around, the Compute Engine was configured with 128 vCPUs, 864 GB of RAM and 100 Gbps of egress bandwidth. Like before, Google used y-cruncher to perform calculations. ![]() The first 12 base-9 digits of pi-squared beginning at position 30 trillion (corresponding to ternary position 60 trillion) are: 122644850645. In 2019, the search giant became the first to use a commercial cloud service and solid state drives to set the Pi record at 31.4 trillion digits calculated.Ī team from the University of Applied Sciences of the Grisons swiped the record last year, pushing the total up to 62.8 trillion decimal places. The first 12 base-8 digits of pi-squared beginning at position 20 trillion (corresponding to binary position 60 trillion) are: 601145053032. The value was calculated using Google Cloud’s Compute Engine with 25 nodes and took 121.1 days or around 4 months to. This isn't the first time Google has topped the leaderboard. Google calculates value of Pi to astonishing 31.4 trillion digits. In brief: Google has successfully calculated 100 trillion digits of π, setting a new world record in the process.
