How to define supercomputers?

The fastest and most expensive computers available at any given time are generally called supercomputers. What makes these machines the fastest is usually their adoption of a new technology or computer architecture that later finds its way into standard computers.

Supercomputers have the most processing power of computers available. They are designed to perform large amounts of numeric computation quickly. They are a class of computers designed for extremely high performance.

Initially, the term supercomputer only applied to the larger mainframe machines, today, the term also includes parallel processing machines.

Technologies that are vital to supercomputers include thermodynamics, surface analysis, mathematics, material science, device physics, very large scale integrated circuits, sophisticated manufacturing technology, robotics, computer-aided design software and etc.

In other worlds, the supercomputer is the result of a vast spectrum of interdisciplinary research and advanced development work.

They are primarily designed for high speed computation, especially for scientific research or the defense industry, but their use is growing rapidly in business as supercomputer prices decrease.

Some applications require extraordinary speed, accuracy and processing capabilities - such as sending astronaut into space, controlling missile guidance systems and satellites, forecasting the weather, exploring for oil, and assisting with some kinds of scientific research.

The first supercomputer is generally considered to be the Control Data CDC 6600, designed by Seymour Cray in 1964.  From CDC 66000, to a wave of new machines by Cray Research in the 1970s, and early 1980s, supercomputing expanded possibilities for modeling the Department of Defends nuclear war scenario, weather forecasting and other areas requiring extensive processing power.

Large System Computing

Large systems consist of mainframe computers, minicomputers and supercomputers.

They are typically multi-user computer system in which many users share the same computing resources at the same time (time sharing).

Mainframe computer and supercomputers can be very expensive to purchase and maintain, so only large corporations can afford them. This kind of computer normally owned by corporations and government agencies that devote entire buildings to their computing divisions.

The computing power of mainframe computer is usually shared by many users.

That means that the operating system of a mainframe computer allows many computer users to participate simultaneously. In this multiuser systems, several terminal are connected to the computer, and each person using the system can simultaneously use several programs in the system.

Mainframe computers are typically used for business applications where a large number of transactions are processed.

They are fast in processing speed and have large storage capacity. Mainframe computers have dramatically increased in power over the last two decades and continue to provide complex massive data handling.

Mainframe computer can process millions of program instruction just in a blink, Large organizations rely on these room-sized systems to handle large programs with lots of data.

Supercomputers have the most processing power of computers available. They are designed to perform large amounts of numeric computation quickly.

They are primarily designed for high speed computation, especially for scientific research or the defense industry, but their use is growing rapidly in business as supercomputer prices decrease.

Supercomputer is commonly used by the popular media to describe certain types of computer architectures that are, in some sense the most powerful available.

Supercomputers are also very valuable for large model simulation and complex mathematical calculations.
