Supercomputers were introduced in the 1960's as the world's most advanced computer. These computers were used for complex calculations such as forecasting weather and quantum physics. Today, supercomputers are one of a kind; they are fast and very advanced. The term supercomputer is always evolving as tomorrow's normal computers are today's supercomputer. As of November 2008, the fastest supercomputer is the IBM Roadrunner. It has a theoretical processing peak of 1.71 petaflops and has currently peaked at 1.456 petaflops.
The fastest type of computer. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration.The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently.
