Extremely Powerful Computer
A supercomputer is a computer that performs at or close to the current highest operational rate for computers, which is called the peak performance rate. Supercomputers have traditionally been used for scientific and engineering applications that require the processing of extremely large databases or the execution of large amounts of computation (or both). Although technological advances such as multi-core processors and GPGPUs (general-purpose graphics processing units) have enabled powerful machines to be used for personal purposes (see: desktop supercomputer, GPU supercomputer), a supercomputer is defined as a machine with exceptional performance by definition.
At any given time, there are a handful of well-publicized supercomputers that operate at extremely high speeds when compared to all other computers in the world. The term is also sometimes used to refer to computers that are significantly slower (but still impressively fast). The largest and most powerful supercomputers are actually a collection of multiple computers that work together in parallel. SMP (symmetric multiprocessing) and massively parallel processing (MPP) are two approaches to parallel processing that can be used in general (MPP).
Among the most notable supercomputers throughout history are:
Seymour Cray was the designer of the CDC (Control Data Corporation) 6600, which was the world’s first commercially successful supercomputer. The CDC 6600, which was introduced in 1964 and had a single CPU, cost $8 million at the time, which is the equivalent of $60 million today. The CDC was capable of processing three million floating point operations per second (flops).
Cray went on to found a supercomputer company in 1972, which he named after himself. Despite the fact that the company has changed ownership several times, it is still in operation. Earlier this year, Cray and Microsoft announced the release of the CX1, a $25,000 personal supercomputer aimed at markets such as the aerospace and automotive industries, academia, financial services, and the life sciences industry.
IBM has historically been a fierce competitor. The company’s Roadrunner supercomputer, which was once the fastest in the world, was twice as fast as IBM’s Blue Gene and six times as fast as any other supercomputer available at the time. IBM’s Watson is well-known for using cognitive computing to defeat champion Ken Jennings on Jeopardy!, a popular television quiz show, in 2011.
What Does the Phrase “Supercomputer” Mean?
An example of a supercomputer is a computer that is designed with the architecture, resources, and components necessary to produce massive amounts of computing power. Supercomputers of today are comprised of tens of thousands of processors, each of which is capable of performing billions or trillions of calculations or computations every second.
The Supercomputer, according to Techopedia
Supercomputers are primarily intended for use in large enterprises and organisations that require a large amount of computing power to function efficiently. When a process is executed on thousands of processors at the same time or distributed among them, a supercomputer incorporates architectural and operational principles from parallel and grid processing into its architecture and operations. Supercomputers, despite the fact that they contain thousands of processors and occupy a large amount of floor space, contain the majority of the key components of a typical computer, including a processor(s), peripheral devices, connectors, an operating system, and applications.
As of 2013, the IBM Sequoia supercomputer is the fastest supercomputer ever built. More than 98,000 processors enable it to process at a rate of 16,000 trillion calculations per second, thanks to the high number of processors.
