Fastest Title Goes To Japan’s Supercomputer

A Japanese Supercomputer stole the title for the worlds fastest and best performing machine from China. The new supercomputer was built by Fujitsu Co.

So how fast is the worlds fastest machine? Well this Japanese government funded ‘K Computer’ is able to perform 8 quadrillion calculation a second. This supercomputer tops all the rest by far, having the capability of calculation more than the next five supercomputers combined. This is something Japan has been working for since the title was lost for seven years.

As for the specs of the supercomputer it is composed of 68,544 processors, each equipped with eight cores for a total 548,352 electronic brains. The machine uses 9.89 megawatts, which is enough to power 9,000 homes per year, but that is nothing compared to the other top 10 supercomputers and is contained in 672 refrigerator-sized computer racks at Riken’s Advanced Institute for Computational Science in Kobe in western Japan.

As you would imagine a computer of this magnitude and capability would cost a pretty penny. The Japanese government invested more than 100 billion yen ($1.25 billion). The reason for such a massive machine, Japanese officials have stated, is to help with medical break throughs. In addition to developing breakthroughs in drugs, materials, new technologies, and being able to predict climate and weather change.

If you thought the supercomputer was ‘super’ now, could you actually believe it’s not finished. The name for the computer was given to it after the Japanese word “kei” for the number 10 quadrillion. 10 quadrillion is the aim for the number of calculation they want the computer to achieve. It has been said that this target will be complete in 2012. Till then it will probably remain the worlds fastest supercomputer.
