Google Employee calculated Pi to a record 31 trillion digits

Emma Haruka Iwao

Emma Haruka Iwao, a Google Employee from Japan have calculated Pi to a new world record number of digits. Iwao works as a cloud developer advocate at Google calculated the pi at 31,415,926,535,897 digits breaking the previous record of 22,459,157,718,361 digits set in 2016.

Iwao used the same y-cruncher program to calculate pi as the past record holder did, but she used with the advantage of Google’s cloud-based compute engine. Iwao used 25 virtual machines which took 121 days to calculate the 31 trillion digits of pi took 170 terabytes of data.

The previous record holder, Peter Trueb used just a single fast computer equipped with two dozen 6TBs of hard drives to control the large dataset that was produced which took just 105 days to complete.

Keeping the large numbers aside which significantly has no such uses in the real world, even NASA uses only 15 digits of pi to send spacecraft into space, and measuring the visible Universe’s circumference to the precision of a single atom would take just 40 digits.

Google have provided the detailed view of the whole mathematics behind the calculation of pi in a blog.
