The Japanese ‘K’ Computer has just been awarded the top spot as the world’s most powerful supercomputer, and in fact its performance simply laps the competition. The ‘K Computer’ is currently three times faster that its Chinese rival that previously held the top position.
The ‘K Computer’ has been built by Fujitsu and is located at the Riken Advanced Institute for Computational Science in Kobe, Japan.
The ranking of the top 500 computers is determined by running a standard mathematical equation. The winning computer was capable of making 8.2 quadrillion calculations per second. In more technical terms, this was done in 8.2 petaflops per second. The performance of the ‘K Computer’ was equivalent to linking around one million desktop computers.
The ‘K Computer’ is made up of 672 cabinets filled with system boards. The system is considered to be energy efficient, but it still make use of enough electricity to power around 10,000 homes at a price of around $10 million per year.
As if the power is not sufficient, the research lab housing the ‘K Computer’ plans to increase its size to 800 cabinets. This will raise its current speed, which already surpasses five of its closest competitors.
‘K’ is short for the Japanese word “Kei”, which means 10 quadrillion. This is the ultimate goal for the number of calculations the computer will eventually be able to perform per second.
