Abstract:
We have calculated 31.4 trillion digits of Pi in 2019 and broke the world record in the Pi computation. The process took about four months and 200 TiB of storage. Record-breaking Pi calculations have traditionally been done on supercomputers and special-made hardware, but we did it on Cloud for the first time. This talk will discuss the nature of the calculation, the architecture, challenges and techniques, and of course the brief history of Pi computation. Calculating Pi has been the speaker's childhood dream and this talk will also explain how the small dream grew to the new world record.

Background:
As a child, Iwao became interested in pi. She was inspired by Japanese mathematicians, including Yasumasa Kanada. She studied computer science at the University of Tsukuba, She was awarded the Dean's Award for Excellence in 2008, before starting graduate studies in computing. Her master's dissertation considered high performance computer systems.After graduating, Iwao took on several software engineering positions, working on site reliability for Panasonic, GREE and Red Hat.

Career
After joining Google in 2015, Iwao became a Cloud Developer Advocate in 2017. She originally worked for Google in Tokyo, before moving to Seattle in 2019. Iwao focuses on the use of the Google Cloud Platform (GCP), as well as supporting application developers. She works to make cloud computing accessible for everyone, creating online demos and teaching materials.
