Google’s Emma Haruka Iwao
Breaks Pi World Record Just in time for Pi Day, the world record for
most accurate value of pi has been broken. Iwao, who has worked at Google for nearly
four years, found the new digits of pi by
using the company’s cloud computing service. She managed to calculate pi to 31 trillion digits.
That's 9 trillion more than the previous record. Iwao’s calculations were done using a y-cruncher,
a program for multi-core systems that is able
to compute constants to trillions of digits. Her calculation took 121 days to complete,
using 25 virtual machines and 170 terabytes of data. That’s roughly the same amount of data as
is currently stored in the Library of Congress. Iwao is excited to hold the new world record,
and doesn’t plan to stop there. Emma Haruka Iwao,
via BBC News Because all of this data is stored in the cloud,
Google has published the computed digits
online for anyone to download and use for free.
