Y-cruncher has certain limits, and we are well below those limits. ![]() “So does the Google Cloud infrastructure. “Computers continue to get better,” she said. ![]() And you can read a pair of blog postings by Iwao and the Google Cloud team to learn more about how the digits were done.Įmma Haruka Iwao is a senior developer advocate for the Google Cloud Platform. ![]() You can check out the digits yourself via Pi.Delivery, a website created by the Google Cloud Platform Developer Advocacy team. That’s more than four times the amount of data processed in 2019. Roughly 82,000 terabytes of data were processed, using a pi-calculating program known as y-cruncher. Thanks to upgrades in Google Cloud’s Compute Engine and increases in throughput, Iwao and the Google team were able to get 100 trillion digits in 157 days of calculation time, which is just a little more than a month longer than the 121 days it took for the 31.4 trillion-digit calculation in 2019. “We thought, OK, 100 trillion sounds reasonable, and a significant advancement over the past record.” “By combining all the new features that were introduced in the last three years, I thought we would be able to break a record again, and not just by a few digits, but by a good margin,” Iwao told GeekWire. The state of the art has been moving forward at Google Cloud as well. Also, note that there are gaps in the years shown on the horizontal axis. The vertical axis reflects the number of digits on a logarithmic scale. This chart shows how the accuracy of pi calculations has improved over the millennia. The Google Cloud record was broken less than a year later, and in 2021, that record was broken in turn (with a precision of 62.8 trillion digits, or pi times 20 trillion). Since 2019, the state of the art in computer science and engineering has been moving forward at an accelerating pace. As a developer advocate for Google Cloud, what better way to demonstrate the power of your cloud computing service than by leading the pi pack? The quest to push the upper boundary of pi helps scientists test supercomputers and develop algorithms that can be used in advanced data analysis.That’s what motivated Iwao’s team to do the calculation to an accuracy of 31.4 trillion digits (pi times 10 trillion) back in 2019. The previous record of 50 trillion digits was set by Timothy Mullican from the US, who achieved the feat after eight months of processing in January 2020. The number π (pi) is a constant in mathematics that is roughly equal to 3.14159, and is the ratio of a circle’s circumference to its diameter. Researchers haven’t revealed the exact numbers involved in the extra 12.8 trillion digits, as they are waiting on the Guinness Book of Records to certify their achievement, but say the final 10 digits they discovered are ‘7817924262’. The previous record was calculated to 50 trillion figures, and was set in 2020, said experts from Graubuenden University of Applied Sciences in Chur, Switzerland. Pi has been calculated to an astonishing 62.8 trillion figures by a team of Swiss scientists who spent 108 days working it up – 3.5 times as fast as the previous record.
