A new supercomputer from China has topped the latest list of the world's most powerful machines. The 93 petaflop Sunway TaihuLight is installed at the NationalSupercomputing Centre in Wuxi. At its peak, the computer can perform around 93,000 trillion calculations per second
 
Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, including quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modeling....
 
The results are in, and they're not a huge surprise: For the fifth consecutive time, China's Tianhe-2 remains the fastest supercomputer in the world, with a Linpack benchmark performance of 33.86 petaflops, or quadrillions of floating-point calculations per second
 
According to the TOP500 list of the world's fastest supercomputers, Tianhe-2 boasts a speed of 33.86 petaflops (one petaflop is one quadrillion floating-point calculations per second), nearly double the United States' second-place computer, Titan (housed at the Oak Ridge National Laboratory in Tennessee).
 
At 100 billion Yen ($1.25 billion), K is the most expensive supercomputer ever built, too. Looking forward, the next target is exaflops — 1,000 petaflops. Realistically, we should hit 100 petaflops in the next few years, and exaflops a few years after that (2018-2020).
 
Now Oak Ridge hopes to bolster the performance of that supercomputer by building the world's fastest data storage system. After a competitive bid process, the Laboratory selected DataDirect Networks to build the file system. The system, which will be named Spider II, will have a capacity of 40 petabytes.
 
Key Difference: A supercomputer is a powerful computer which is used for processing data at fastest possible speed. ... Thus, the primary focus of asupercomputer is speed, whereas for a mainframe it is to deal with extensive amount of data. Mainframe computers are not as powerful as supercomputers.

Computers versus Brains. For decades computer scientists have strived to build machines that can calculate faster than the human brain and store more information. The contraptions have won. The world's most powerful supercomputer, the K from Fujitsu, computes four times faster and holds 10 times as much data.
 
The most powerful computer known is the brain. The human brain possesses about 100 billion neurons with roughly 1 quadrillion — 1 million billion — connections known as synapses wiring these cells together
 
WABURUDISHAJI mara nyingi hubamba dili za kitajiri kutokana na kuwa na mikataba ya kibiashara inayowaingizia mikwanja mirefu.
