Abstract
Supercomputer also known as gigantic computer, refers to a kind of computer with the best performance, the strongest function, the fastest operation speed and the largest storage capacity among all kinds of computers in an era. Supercomputer is a kind of complex electronic giant system, has huge numerical calculation ability and data processing ability, and can calculate large and complex tasks that ordinary personal computers and servers cannot complete. It has been used in high-end technology and cutting-edge scientific research at the beginning. With the continuous progress of science and technology, the upgrading speed of computer is very fast. Therefore, Supercomputer has distinct temper of times, and its evaluation standard is also dynamic. It is an important embodiment of scientific and technological strength of the country and plays a huge role in promoting national economic development, social progress and national defense construction. The paper reviews the development of the international supercomputer and overview of supercomputer development in China. It analyzes the current situation of supercomputer R&D, shows the supercomputer technology problem and innovation-storage access wall, communication wall, reliability wall, energy consumption wall. This paper also looks forward to the future of supercomputer, so as to provide some reference for scholars in related fields.
Highlights
Supercomputer, known as gigantic computer, refers to a kind of computer with the best performance, the strongest function, the fastest operation speed and the largest storage capacity among all kinds of computers in an era and it is a complex electronic giant system. [1] Supercomputer has huge numerical calculation ability and data processing ability, and can calculate large and complex tasks that ordinary personal computers and servers cannot complete
In the mid-1980s, it stipulated that a digital electronic computer with floating-point operation speed of more than 100 million times per second, word length of 64 bits and main memory capacity of 4-16MB was considered a supercomputer in the industry field. [2]
With the improvement of semiconductor and integrated circuit technology, computers develop rapidly, resulting in the emergence of small, medium and large computers, which are widely used in industries, science and technology, universities, governments, military and other fields and departments all over the world, greatly promoting the development of productivity
Summary
Supercomputer, known as gigantic computer, refers to a kind of computer with the best performance, the strongest function, the fastest operation speed and the largest storage capacity among all kinds of computers in an era and it is a complex electronic giant system. [1] Supercomputer has huge numerical calculation ability and data processing ability, and can calculate large and complex tasks that ordinary personal computers and servers cannot complete. Great progress has been made in computer software, with the functions of operating system continuously enhanced and improved, various high-level languages and their compilers widely used, and various algorithms gradually improved. All of these provide technical support for the development and application of computer system software with better performance. In the case of demand traction and technology promotion, supercomputer system came into being It has been used in high-end technology and cutting-edge scientific research at the beginning. It is an important embodiment of scientific and technological strength of the country and plays a huge role in promoting national economic development, social progress and national defense construction
