# A Google worker broke the world document for calculating pi

Posted in Technology News

Google engineer Emma Haruka Iwao has calculated pi to 31 trillion digits, breaking the world document.
Pi is an infinite quantity important to engineering.
She ran her calculations over Google's cloud service, marking one other world-first.
The calculation took round 4 months, or 121 days.
Google worker Emma Haruka Iwao used Google's cloud computing service to interrupt the world document for calculating pi, an infinite quantity very important to engineering.
Most individuals might be acquainted with the primary few digits of pi from geometry class (three.14...). It is the quantity you get whenever you divide a circle's circumference by its diameter.
Iwao — a cloud developer advocate who has been working at Google for over three years — efficiently calculated pi to 31 trillion digits, beating the earlier document by 9 trillion. Google introduced her accomplishment on March 14, which simply so occurs to be pi day.
Doing so required enormous quantities of knowledge processing. Utilizing this system y-cruncher on a Google Compute Engine cluster, she ate via 170 terabytes of knowledge over about 4 months. To present a way of scale, the BBC writes that 200,000 music tracks whole simply 1 terabyte.

Iwao says that that is the primary time cloud computing has been used to calculate pi and break the document. A Yahoo engineer used the corporate's cloud tech in 2010 to calculate the two quadrillionth digit of pi, however didn't calculate all of the numbers in between.
Iwao advised the BBC that she's not accomplished with pi. "There isn't a finish with pi, I might like to attempt with extra digits," she mentioned.
