Emma Haruka Iwao, who works at Google, used Google Cloud computing to calculate 31.4 trillion digits of pi.
This is the first time some used publicly available cloud software for an enormous pi calculation. Peter Trueb set the previous world record in 2016,
Emma loved pi at school. What’s more, one of her professors in university, Daisuke Takahashi, held the record for the most-calculated digits of pi using a supercomputer.
“You need a pretty big computer to break the world record,” says Iwao. “But you can’t just do this with a computer from a hardware store, so people have previously built custom machines.”
In September of 2018, she started to how to calculate more digits of pi and how to store the data calculations. Rather than building a whole new machine to do the work, Emma used Google Cloud.
Snapshots of Iwao’s calculations are now publicly available for enthusiast mathematicians to copy and use. As for Emma Iwao, she can relax a little bit more,
“I was confident in the infrastructure, but I was nervous for the entire thing,” she says. “But it’s like when you take a math test, no matter how confident you are, you feel better when you’ve got your results.”
