This is almost everything you need to know about supercomputers…
Few more things you need to know (from top500.com):
“China maintained its No. 1 ranking on the 47th edition of the TOP500 list of the world’s top supercomputers, but with a new system built entirely using processors designed and made in China. Sunway TaihuLight is the new No. 1 system with 93 petaflop/s (quadrillions of calculations per second) on the LINPACK benchmark.”
This is how Sunway TaihuLigh looks:

In this photo released by the Xinhua News Agency and taken on June 16, 2016, the Sunway TaihuLight, a new Chinese supercomputer, is seen in Wuxi, eastern China’s Jiangsu Province. A supercomputer from China has topped a global list of the fastest systems for a seventh straight year, and for the first time the winner, Sunway TaihuLight, uses only Chinese-designed processors instead of U.S. technology.
