Opinion obvious: Computer And Its Generation Computers

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer.

What may come

Supercomputers play an important role in the field of computational scienceand are used for a wide Ckmputer of computationally intensive tasks in various fields, including quantum mechanicsweather forecastingclimate researchoil and gas explorationmolecular modeling computing the structures and properties of chemical compounds, biological macromoleculespolymers, and crystalsand physical simulations such as simulations of the early moments of the universe, airplane and spacecraft aerodynamicsthe detonation of nuclear weaponsand nuclear fusion.

They have been essential in the field of cryptanalysis.

Supercomputers were introduced in the s, and for several decades the fastest were made by Seymour Cray at Control Data Corporation CDCCray Research and subsequent companies bearing his name or monogram. The first such machines were highly tuned conventional designs https://amazonia.fiocruz.br/scdp/blog/purpose-of-case-study-in-psychology/antigone-creon-pride-vs-power.php ran faster than their more general-purpose contemporaries. Through the decade, increasing amounts of parallelism were added, with one Generaton four processors being typical.

In the s, vector processors operating on large arrays of data came to dominate. A notable example is the highly successful Cray-1 of Vector computers remained the dominant design into the s. From then until today, massively parallel supercomputers with tens https://amazonia.fiocruz.br/scdp/blog/purdue-owl-research-paper/eli-lilly-and-the-pharmaceutical-chemist.php thousands of Comptuer processors became the norm.

The US has long been the leader in the supercomputer field, first through Cray's almost uninterrupted dominance of the field, and later through a variety of technology companies. Japan made major strides in the field in the s and 90s, with China becoming increasingly active in the field.

It still used high-speed drum memoryrather than the newly emerging disk drive technology. The IBM used transistorsmagnetic core memory, pipelined instructions, prefetched data through a memory controller and included pioneering random access disk drives. The IBM was completed in and despite not meeting the challenge of a hundredfold increase in performance, it was purchased by the Los Alamos National Laboratory. Customers in England and France also bought the computer and it became the basis for the IBM Harvesta supercomputer built for cryptanalysis.

The third pioneering supercomputer project in the early s was the Atlas at the University of Manchesterbuilt by a team led by Tom Kilburn. He designed the Atlas to have memory space for up to a million words of 48 bits, but because magnetic storage with such a capacity was unaffordable, the actual core memory of Atlas was only 16, words, with a drum providing memory for a further 96, words. The Atlas operating system swapped data in the form of pages between the magnetic click here and the drum. The Atlas operating system also introduced time-sharing to supercomputing, so that more than one program could be executed on the supercomputer at any one time. The CDCdesigned Clmputer Seymour Computer And Its Generation Computerswas finished in and marked the transition from germanium to silicon transistors.]
