Google employee breaks world record for calculating pi

World Record 31.4 Trillion Digits of Pi Calculated By Google Scientist

So many in fact, that she now proudly holds the Guinness World Record for most calculated digits of pi: 31,415,926,535,897 digits. In addition to reaching such a high calculation, this is also the first time the world record was broken using the cloud. Calculating the digits of pi is a method of testing supercomputers, as well as a way for mathematicians simply to engage in some friendly competition. The calculation was completed with 25 virtual machines in 121 days and took up 170TB of data.

March 14 was chosen as the global day of celebration because 3.14 translates to 3/14/YEAR in the American calendar.

"In the past super computer and desktop computers were used to calculate pi, and today this is the first time a cloud was calculated to beat the world record", she said.

"Pi seems simple - it starts with 3.14", she says.

Google engineer Emma Haruka Iwao has calculated pi to 31 trillion digits, breaking the world record.

Emma further explains that this was possible using a Pi-benchmark, y-cruncher which was developed by Alexander J. Yee on Google Compute Engine virtual machine cluster. But even if you don't work for Google, you can apply for various scholarships and programs to access computing resources.
