SuperComputers

A supercomputer is a computer complex, consisting of multiple processors, which accesses the same memory and central functions concurrently and coordinated closely in cooperatie so, supercomputer can reach a total computing performance impressive.

The manner of calculating the supercomputers is called “parallel computing”. The number of interconnected processors of a supercomputer over certain models even 100,000. For comparison, a normal computer, called a “scalar”, contains a single central processor.
To keep the cost of such a supercomputer from an acceptable level, there are architectures supercomputers making use of cheaper processors and more slow, but very numerous, grouped in the so-called cluster.

Among the first companies that have produced supercomputers market ( “commercial”) was included by the company Cray years 1970, so named after its founder Seymour Cray.
The first supercomputer or sold and installed official was famous Cray-1, which in 1976 reached a speed calculation 130 MegaFLOPS (130 million instructions with the second comma furniture).
For example of a normal PC today can reach several GigaFLOPS (in other words, the PC today is already about 10 times faster at this kind of instruction than supercomputer of 1976).

In this area there is a list of the fastest 500 supercomputere the world ( “Top 500″-http: / / www.top500.org), which is based on standardized test called “Linpack.”

Besides these supercomputers trade, and of course there supercomputers military line (which can not be bought on the market), whose computing power is held abolish secret, but we can easily imagine that this is significantly higher than the mark.
