The calculation used a multithreaded program called y-cruncher using over 25 machines for 121 days. In March 2019 Iwao calculated the value of pi to 31,415,926,535,897 digits (Equal to ⌊ π × 10 13 ⌋), using 170 terabytes (TB) of data. She works to make cloud computing accessible for everyone, creating online demos and teaching materials. Iwao offers training in the use of the Google Cloud Platform (GCP), as well as supporting application developers. She originally worked for Google in Tokyo, before moving to Seattle in 2019. Iwao joined Google as a Cloud Developer Advocate in 2015.
#FIRST 100 TRILLION DIGITS OF PI SOFTWARE#
After graduating, Iwao took on several software engineering positions, working on site reliability for Panasonic, GREE and Red Hat. Her master's dissertation considered high performance computer systems. She was awarded the Dean's Award for Excellence in 2008, before starting graduate studies in computing. She studied computer science at the University of Tsukuba, where she was taught by Daisuke Takahashi.
She was inspired by Japanese mathematicians, including Yasumasa Kanada. Early life and education Īs a child, Iwao became interested in pi. This record was surpassed in 2020 by Timothy Mullican who calculated 50 trillion digits, but she reclaimed the record in 2022 with 100 trillion digits. In 2019 Haruka Iwao calculated the then world record for most accurate value of pi (π) which included 31.4 trillion digits, exceeding the previous record of 22 trillion. Guinness World Record for most accurate value of pi (π) Įmma Haruka Iwao is a Japanese computer scientist and cloud developer advocate at Google.
