pi

Led by University of Tsukuba professor Daisuke Takahashi, the research team performed the calculation using a massive parallel processing (MPP) supercomputer called the T2K Tsukuba System, which consists of 640 high-performance computers clustered together to achieve processing speeds of 95 teraflops (95 trillion floating-point operations per second). The supercomputer calculated pi to 2,576,980,377,524 decimal places in 73 hours 36 minutes.

By comparison, it took the previous record holders about 600 hours to perform their calculation (over 8 times longer than it took the T2K Tsukuba System).
