Google employee breaks world record for calculating pi

Pi dream: Googler sets record for most digits calculated

They made their announcement today, on Pi day which falls on March 14th, or 3.14, the USA format of the date, in its most basic form. Over the 121.1 days, Google used 96 vCPUs, 1.4 TB of RAM, read 9.02 PB of data, and wrote 7.95 PB.

Iwao did her number crunching primarily from Google's office in Osaka, Japan, where she works at as a developer and advocate for Google Cloud. The previous record, set by Peter Trueb in late 2016, was 22.4 trillion digits.

The world record for manually calculating pi is held by British mathematician William Shanks, who managed 527 digits without a computer.

Her milestone was certified by Guinness World Records on Wednesday, making her the third woman to set a world record for calculating the number. Pi is an irrational and transcendental number and it continues infinitely without repetition or pattern. In addition to reaching such a high calculation, this is also the first time the world record was broken using the cloud. It's the number you get when you divide a circle's circumference by its diameter. No word yet on whether she will be celebrating her achievement the American way - by eating actual pie.

Googler Emma Haraku Iwao took her fascination with pi all the way to 31.4 trillion digits. "The biggest challenge is you need a lot of storage". When I was a kid, I downloaded a program to calculate pi on my computer, ' Emma said.

Emma said in the post that pi has been computed to 31.4 trillion decimal places or 31,415,926,535,897 digits to be exact, using Google Compute Engine, powered by Google Cloud. I was very fortunate that there were Japanese world record holders that I could relate to.

In the past, if you wanted to share the longest known version of pi, you had to put it on a hard drive and mail it. During the entire time it took for calculations, the Google Cloud server were kept switched on to avoid any interruptions.

When I think of pi, I think of three digits: 3.14.
