The supercomputer is the fastest type of computer. Supercomputers are very costly and are employed for specific applications that require immense amounts of mathematical calculations. For instance, weather forecasting necessitates a supercomputer. Other uses of supercomputers contain animated graphics, nuclear energy research, fluid dynamic calculations, and petroleum exploration.
The chief differentiation between a supercomputer and a mainframe is that a supercomputer channels all its power into executing some programs as fast as possible, whereas a mainframe uses its power to carry out many programs concurrently.
Supercomputers are used for exceedingly calculation-intensive tasks like problems connecting weather forecasting, quantum mechanical physics, climate research (together with research into global warming), molecular modeling (computing the structures and properties of chemical compounds, polymers, biological macromolecules, and crystals), physical simulations (like simulation of airplanes in wind tunnels, imitation of the detonation of nuclear weapons, and research into nuclear fusion), cryptanalysis, and the like.
Supercomputers using tradition CPUs custom gained their speed over conventional computers through the employ of ground-breaking designs that allow them to carry out many tasks in parallel, as well as complex detail engineering. They are inclined to be specialized for definite types of computation, generally arithmetical calculations, and carry out poorly at more general computing tasks. Their memory hierarchy is very cautiously designed to make sure the processor is kept fed with data and instructions at all times— in actual fact, much of the performance difference between slower computers and because of the memory hierarchy of Supercomputers the I/O systems tend to be designed to support high bandwidth, with latency less of an issue, because it is not used for transaction processing.
