    Abstract

    We present a new record on computing specific bits of Pi, the mathematical
    constant, and discuss performing such computations on Apache Hadoop clusters.
    The specific bits represented in hexadecimal are 0E6C1294 AED40403 F56D2D76
    4026265B CA98511D 0FCFFAA1 0F4D28B1 BB5392B8. These 256 bits end at the
    2,000,000,000,000,252nd bit position, which doubles the previous known record.
    The position of the first bit is 1,999,999,999,999,997 and the value of the two
    quadrillionth bit is 0. The computation is carried out by a MapReduce program
    called DistBbp.
