Yahoo's Hadoop Cloud Computing Used To Find two-quadrillionth digit of pi [bbc.co.uk]
A researcher has calculated the 2,000,000,000,000,000th digit of pi - and a few digits either side of it.
Nicholas Sze, of technology firm Yahoo, determined that the digit - when expressed in binary - is 0.
Mr Sze used Yahoo's Hadoop cloud computing technology to more than double the previous record.
The computation took 23 days on 1,000 of Yahoo's computers, racking up the equivalent of more than 500 years of a single computer's efforts.
