Supercomputers are a specialized type of computers which are used for complicated tasks like weather forecasting as well as biological researches. They are very expensive and are also responsible for working out many mathematical calculations in no time. The Blue Gene/L is the fastest computer in the world. It is in the national laboratory of Japan. It can execute up to 35.6 trillions of mathematical problems per second.
The chief difference between a supercomputer and normal PC's:
1) Supercomputers are a specialized type of computers used for laboratory researches, weather forecasting, nuclear researches, and data analysis and in animation industry etc.
2) Supercomputers execute power into a few programmes, while computers run all applications concurrently.
Working and market:
Supercomputers have large processing capacity. It is mainly known for the great speed of calculation.
Supercomputers introduced by Symour cray. He is associated with Control Data Corporation. Samour cray introduced supercomputers with new design. He introduced those computers by his own company 'Cray research.'
In 1980's large number of smaller competitors entered into the super computer market. Market crashed.
Now the cray, IBM and Hewlett-Packard are building supercomputers. The IBM Roadrunner located in Los Alamos National Laboratory is the fastest supercomputer in the world.
