Googler Emma Haruka Iwao recently beat the world record for most-calculated digits of pi. Here’s how she used Google Cloud to do it.
Whether or not you realize it, pi is everywhere you look. It’s the ratio of the circumference of a circle to its diameter, so the next time you check your watch or see the turning wheels of a vehicle go by, you’re looking at pi. And since pi is an irrational number, there’s no end to how many of its digits can be calculated. You might know it as 3.14, but math and science pros are constantly working to calculate more and more digits of pi, so they can test supercomputers (and have a bit of healthy competition, too).
While I’ve been busy thinking about which flavor of pie I’m going to enjoy later today, Googler Emma Haruka Iwao has been busy using Google Compute Engine, powered by Google Cloud, to calculate the most accurate value of pi—ever. That’s 31,415,926,535,897 digits, to be exact. Emma used the power of the cloud for the task, making this the first time the cloud has been used for a pi calculation of this magnitude.
Here’s Emma’s recipe for what started out as a pie-in-the-sky idea to break a Guinness World Records... continue reading
