Supercomputers

Supercomputer is a computer far exceeding the capabilities commonly used computers, in particular Featuring many more computing power. This term has emerged in the '60s in relation to computers manufactured by the CDC and later by Cray. They were produced in dozens of copies and cost several million dollars. Currently, most supercomputers are single copies, designed and manufactured to order. The costs of their production back to 200 million U.S. dollars [1]. The fastest supercomputer is currently Tianhe-1A, which is installed in the NSC Tianjin, China. Technological advances in information technology makes the machine counted several years ago to a class of supercomputers today, can hardly compete in terms of productivity with personal computers. For example, the computing power of one of the most powerful supercomputers in the eighties Cray-2 was about 4 GFLOPS, which is comparable to the computational power of one core processor to the low-cost personal computers. Supercomputers are primarily used to carry out complex physical simulations such as weather forecasting, climate research, modeling of chemical reactions, the study of aerodynamics and aircraft study of aging nuclear weapons.
