Google employee breaks the world record for calculating the value of pi

Pi dream: Googler sets record for most digits calculated

Haruka Iwao ran the calculations using the y-cruncher application running on 25 Google Cloud virtual machines. The search giant, using the power of its cloud infrastructure, has set a new record for the most accurate value of pi.

In doing so, Google has also set a new Guinness World Record beating the old one by 9 trillion digits more.

Why it matters: This is the first time the Pi record has been set using a commercial cloud service and the first achieved using solid state drives. In a blog post, Emma said that they managed to successfully compute the Pi value to 31.4 trillion decimal places or 31,415,926,535,897.

Ms Iwao said she had been fascinated by the number since she had been a child.

Mathematician James Grime says that just 39 digits of pi is enough to calculate the circumference of the known universe, and NASA's Jet Propulsion lab only uses 15 digits to calculate interplanetary travel. "When I was a kid, I downloaded a program to calculate pi on my computer".

In mathematics pi is the ratio of a circle's radius to its circumference, has far more digits that continue infinitely without repetition. The previous world record was 22.4 trillion digits and it was achieved back in November, 2016 by Peter Trueb. "At the time, the world record holders were Yasumasa Kanada and Daisuke Takahashi, who are Japanese, so it was really relatable for me growing up in Japan". I would list it here but I suspect that many digits may break the website.

China held that record for five years.

On Friday, the US Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee unveiled the "Summit" supercomputer that can deliver a peak performance of 200 petaflops, or about 200 quadrillion calculations per second.
