Pi : Its longest calculation ever by Japanese Super Computer
The new value of Pi is 2,576,980,370,000 decimal places long. T2K-Tsukuba System, a supercomputer at the University of Tsukuba, Northeast of Tokyo takes the credit of setting a world record for calculating the value of Pi to more than 2.5 trillion decimal places beating the previous record of more than 1.2 trillion places, set in 2002 by a team from University of Tokyo and Hitachi.
This supercomputer is comprised of 640 Quadra-Core AMD Opteron processors and processing speed of 95 Trillion floating-point operations per second. It took 73 hours and 36 minutes (including verification time) to calculate this value which is 8 times faster than the previous record(600 hrs for calculating 1.2 trillion decimal places).
Daisuke Takahashi, Associate Professor of Centre for Computational Sciences wrote the two programs for this calculation.
This is yet another step towards exploring the endless value of the geometrical constant and a way of testing the super computer.

Not sure How it makes sense to waste such a amount of computing power on something which does have much value. What would that long value of Pi before future growth

i just did a calculation of Pi to the 10,000,000′th digit.. took less than a minute.
honestly with all of today’s supercomputers this is the best calculation of Pi to-date?
