Supercomputers are the fastest computing systems and are usually used for handling huge amount of data and inferring complex phenomenon like climate change, nuclear reactions, origin of universe, etc. The standard unit of measuring computational power is FLOPS – floating point operations per second.
Chinese Supercomputer Sunway Taihulight is ranked fastest in the world, according to Top500 (supercomputer ranking project). This supercomputer has computational ability of 93 petaflops, more than a billion times faster than a normal computer.
The supercomputer requires to be kept under intense cooling system as it can generate higher temperatures due to computations.
Other top ranked countries that own supercomputer include USA, China, Germany, Japan and France.
