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