Google sets new Guinness World Record on Pi Day

  1. Google is celebrating Pi Day, the annual observation of the mathematical constant π, in a big way. The search giant, using the power of its cloud infrastructure, has set a new record for the most accurate value of pi.

    From September to January, Emma Haruka Iwao, a developer advocate for Google Cloud, ran a computation of Pi to 31.4 trillion decimal places—31,415,926,535,897 to be exact, or π * 10^13. The feat was achieved using a Google Compute Engine virtual machine cluster to run the Pi benchmark program y-cruncher.

    Interestingly enough, the computation resulted in a total of 10 PB of reads and 9 PB of writes – the latter being enough to destroy the average consumer solid state drives roughly 10 times.

    From start to finish, the computation took 121 days. It was verified twice, once using the Bellard 7-term BBP formula and again with the original 4-term BBP formula.

    Iwao’s calculation set a new Guinness World Record. It’s nearly nine trillion digits more than the previous world record set by Peter Trueb in November 2016.

    lol get over yourself and your moral high horsing. Why don't you get up from your internet browsing and go feed hungry people? Or is it that you just want everyone here to see how righteous you are?
