  Supercomputer - Wikipedia, the free encyclopedia
Supercomputers introduced in the 1960s were designed primarily by Seymour Cray at Control Data Corporation (CDC), and led the market into the 1970s until Cray left to form his own company, Cray Research.
Today, supercomputers are typically one-of-a-kind custom designs produced by "traditional" companies such as IBM and HP, who had purchased many of the 1980s companies to gain their experience, although Cray Inc. still specializes in building supercomputers.
In the 1970s most supercomputers were dedicated to running a vector processor, and many of the newer players developed their own such processors at a lower price to enter the market.

 Supercomputer   (Site not responding. Last check: 2007-10-21)
Supercomputers are used for highly calculation-intensive tasks as weather forecasting climate research (including research into global warming) molecular modeling (computing the structures and properties of compounds biological macromolecules polymers and crystals) physical (such as simulation of airplanes in wind simulation of the detonation of nuclear weapons and research into nuclear fusion) cryptanalysis and the like.
Their operating systems often variants of UNIX tend not to be as sophisticated those for smaller machines since supercomputers are dedicated to one task at a time than the multitude of simultaneous jobs that up the workload of smaller devices.
The speed of a supercomputer is generally in flops (floating point operations per second); this ignores communication overheads and assumes that all of the machine are provided with data are working at full speed.

 CS 3604 Assignment 2: Supercomputers, Spring 1997
There are three primary limits to performance at the supercomputer level: individual processor speed, the overhead involved in making large numbers of processors work together on a single task, and the input/output speed between processors and between processors and memory.
Both problems had existed before, as most supercomputers had from two to sixteen processors, but they were much easier to deal with on that level than on the level of complexity arising from the use of hundreds or even thousands of processors.
Supercomputers, on the other hand, were designed, built, and bought to work on extremely large jobs that could be handled by no other type of computing system.
