Fastest Computer : A Myth


After the results, many of my friends would be feeling very low. But friends always believe in yourself. Every person has the world fastest computer, i.e. Your BRAIN. One just have to learn, how to use it effectively.India may have launched itself on the world's map of raw computing power with the Eka supercomputer from the Tata group, but even the world's fastest supercomputer cannot match the processing speed of your brain. Scientists reveal that the brain is made up of about one trillion cells with 100 trillion connections between those cells. Estimates put the brain as capable of handling 10 quadrillion instructions per second. Now compare that to the processing speed of the world's fastest supercomputer from IBM at over 475 teraflops (or 475 trillion calculations per second).
What's more interesting is that the world's truly fastest supercomputer - RIKEN's MDGrape-3 will probably never be officially crowned with that title, simply because it is so specialised that it can't run the software (the Linpack benchmark) used to officially rank computing speed. MDGrape-3 is the first machine to break the petaflop barrier - that is 1 quadrillion calculations per second - and is three times faster than the currently-ranked fastest computer in the world, IBM's BlueGene/L.
RIKEN developed the supercomputer along with Intel, and SGI in 2006 to carry out molecular dynamics simulations. In developing drugs, pharmaceutical companies have to analyse thousands of chemical compounds to find out how they will affect the protein-bonding structures in the human body. What takes most computers hours or days to analyse takes MDGrape-3 a few seconds. The functionality is invaluable in drug research since it can drastically cut research time involved in the development of new cures. A subsidiary of pharmaceutical giant Merck has already booked time on the machine.

So friends, don't worry much about results. You might be a RIKEN's MDGrape-3 computer, and world might not be ready enough to judge you, by their officially used ranking methodology. You may be a step ahead from all these generalities. Be confident, work hard, and prove your metal.
