Google’s employee Emma Haruka Iwao Breaks Pi World Record Calculation
Just in time for Thursday’s National Pi Day, the world record for most accurate value of Pi has been broken by Emma Haruka Iwao.
Iwao who has worked with Google for nearly four years took four months or nearly 121 days and used 25 Google Cloud virtual machines and 170 terabytes of data to find the new digits of Pi.
That is roughly the same amount of data that is presently stored in the Library of Congress.
She calculated Pi to a sprawling 31.4 trillion digits which is 9 trillion more than the previous record of 22.4 trillion set by Peter Trueb in 2016.
Iwao’s calculations were done using a y-cruncher, a program for multi-core systems that is able to compute constants to trillions of digits.
Iwao is excited to achieve the new Guinness world record and doesn’t plan to stop there.
“I am still trying to adjust to reality. The world record has been really hard. There is no end with Pi, I would love to try with more digits.” -Emma Haruka Iwao, Via BBC News
Because all of this data is stored in the cloud, Google has published the computed digits online for anyone to download and use for free.
Google made the announcement for her achievement on Thursday but Iwao has been struggling towards this moment since she just 12 years old.
