Google Cloud developer uses AI to calculate 100 trillion digits of pi

Long history of pi gets a new entry thanks to Google Cloud

The long and chequered lifespan of mathematical icon pi has been extended even further thanks to Google Cloud.

Google Developer Advocate, Emma Haruka Iwao, successfully calculated pi to 100 trillion digits using the company’s cloud platform.

What’s even more striking it that this is the second time in just three years that Iwao has broken the record.

Why does this matter?

Mathematicians have been cracking away at calculating pi to its limits since Ancient Egypt, Greece, and Babylon.

Google openly admitted that you might not need to “calculate trillions of decimals of pi” but said the “massive calculation demonstrates how Google Cloud’s flexible infrastructure lets teams around the world push the boundaries of scientific experimentation”.

Though pi related calculations pop up in everything from the theory of relativity to engineering problems and GPS mapping, these types of extreme calculations are generally used as a benchmarking tool by computer scientists, to prove and assess the power of their hardware.

How did they do it?

Google Cloud says it used it’s generally available Compute Engine service to make the record calculation.

The tech giant attributed its improved result compared to last time it made the attempt in 2019 to improved networking and storage.

The project was able to achieve 100 Gbps egress bandwidth, a huge improvement on the 16 Gbps of egress available when they did the 31.4-trillion-digit calculation in 2019.

The project used new network driver Google Virtual NIC (gVNIC), which is integrated with Google’s Andromeda virtual network stack

Google also attributed the success of the project in large part to improved storage, saying that as the “dataset doesn’t fit into main memory, the speed of the storage system was the bottleneck of the calculation”.

For this job they decided to use Balanced Persistent Disc, a new type of persistent disk which Google said offers up to 1,200 MB/s read and write throughout and 15-80k IOPS.

Those who are interested in checking out more about the nitty gritty of the project can head to  GitHub to find the code Google used.

Google will also be hosting a live webinar on June 15 to share more about the experimentation process and results, and you can head here to join.
