On 29th July, 2015, President of the United States, Barack Obama, approved the development of an Exascale Super Computer.
The Exascale Super computer will be 30 times faster and more powerful
than today’s fastest Super Computers. The need to develop such a high
performance Supercomputer comes after China’s surge in high performance
computing. However, the US still tops the list of Supercomputers with 233 high performance machines. China has 37 Supercomputers but they lead the list of the most powerful and high performance supercomputers since June 2013.
Presently, China’s "Tianhe – 2" is the world’s faster Supercomputer.
The Tianhe – 2 can perform 100 Petaflops, i.e quadrillions of floating point operations per second.
The following table shows list of top five most powerful Supercomputers in the world. you can also view complete list of Top 500 Supercomputers in the world.
