Emma Haruka Iwao is a Japanese computer scientist and cloud developer advocate at Google. In 2019 Haruka Iwao calculated the world record most accurate value of pi (π); which included 31.4 trillion digits, exceeding the previous record of 22 trillion.[3][4][5][6][7] This record was surpased in 2020 by Timothy Mulican who calculated 50 trillion digits.[8][9]

Early life and education

As a child, Iwao became interested in pi.[3] She was inspired by Japanese mathematicians, including Yasumasa Kanada.[10] She studied computer science at the University of Tsukuba, where she was taught by Daisuke Takahashi.[11][12] 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.[11] After graduating, Iwao took on several software engineering positions, working on site reliability for Panasonic, GREE and Red Hat.[12]

Career

Iwao joined Google as a Cloud Developer Advocate in 2015.[3] She originally worked for Google in Tokyo, before moving to Seattle in 2019.[2] Iwao offers training in the use of the Google Cloud Platform (GCP), as well as supporting application developers.[13][14][15][16] She works to make cloud computing accessible for everyone, creating online demos and teaching materials.[17]

In March 2019 Iwao calculated the value of pi to 31,415,926,535,897 digits (Equal to ⌊π × 1013⌋), using 170 terabytes (TB) of data.[3][10][18][19][1][20] The calculation used a multithreaded program called y-cruncher using over 25 machines for 121 days.[3][21][17]
