World’s Top 10 Supercomputers with their Cost, Speed and Usage

The history of Supercomputers are dated back to early 60s with development of Atlas, the first supercomputer (installed at Manchester University) with asynchronous processor due to which the processing speed is not measurable but far less than an ordinary desktop computers at your home. But today’s supercomputers have thousands time more processing speed and in fact, thousand time costly too than our desktop computers.


The performance or processing speed of supercomputer is measured in petaflop that is equal to a million billion or a thousand trillion floating point operations per second. These massive machines are not made for fun but rather help scientists, meteorologists to do research or forecast global climate and whether, while some are used being to simulate brain activity or effects of storm or wind on a plane.

 Take a look at world top 10 supercomputers as announced in November 2013 by, the organization updating the list half-yearly.
