K Computer built by Fujitsu Japan has been ranked as the world’s most powerful supercomputer. Mr. K, made up of 672 cabinets of electric circuit boards is claimed to be three times faster than the former Chinese rival and is said to have an equal computing power to a combination of one million desktop computers. The tests revealed that K was able to make 8.2 quadrillion calculations per second and that is why it is named as “K” which is a short term of “Kei” in Japanese, meaning 10 quadrillion. In comparison to running a million desktop computers to produce “K” metric, this system is said to be energy-efficient, yet it consumes enough electricity required to power tens of thousands home costing near 10 million dollars annually.
Such supercomputers are aimed to be used in extreme high-tech computations including research, climate predictions and oil exploration industry etc.
