What is the series of giant machines developed by China?

The Galaxy-1 supercomputer was developed in Changsha in 1983. On December 22, 1983, China's first "Galaxy" supercomputer, which operates more than 100 million times per second, was successfully developed in Changsha by the Computer Research Institute of the National University of Defense Technology. It fills the gap in the domestic supercomputer, and China has become the third country after the United States and Japan to independently design and manufacture supercomputers.

It marks that China has entered the ranks of the world's development of supercomputers.

Galaxy Series. Tianhe series.

Galaxy Series. Galaxy - In November 1983, China's first 100 million times giant electronic computer named "Galaxy" was born in the National University of Defense Technology after five years. Its development was successful, announcing to the whole world:

After the United States and Japan, China has become the country that can independently design and manufacture giant aircraft.

On November 19, 1992, the "Yinhe-" 1 billion supercomputer developed by the National University of Defense Technology passed the national appraisal in Changsha. It fills the gap of parallel supercomputers for large-scale scientific and engineering computing and large-scale data processing in China.

On June 19, 1997, the "Yinhe-" parallel supercomputer developed by the National University of Defense Technology passed the national appraisal in Beijing. The machine adopts a distributed shared storage structure, which is oriented to large-scale scientific and engineering computing and large-scale data processing, with a basic word length of 64 bits and a peak performance of 13 billion times. The aircraft has a number of technologies in the leading position in China, and the comprehensive technology has reached the current international advanced level.

Sunway Taihu Light supercomputer.

Sunway Taihulight is a supercomputer developed by the National Parallel Computer Engineering Technology Research Center and installed in the National Supercomputing Center in Wuxi.

The Sunway Taihu Light supercomputer is equipped with 40,960 China-developed "Shenwei 26010" many-core processors, which use a 64-bit autonomous Shenwei instruction system with peak performance and sustained performance. (1 Beijing is 100 million).

In July 2020, USTC realized the first parallel first-principles computing simulation of 10 million cores on the "Sunway Taihu Light".

In China, it is the famous "Galaxy" series of giant machines.

That was December 22, 1983.

China's first computer with more than 100 million calculations per second, the "Galaxy", was successfully developed in Changsha. Its design host is Professor Ci Yungui, an academician of the Chinese Academy of Sciences and the Chinese Academy of Sciences, and is also known as the father of China's giant machine.

In 2004, the Dawning 4000A was successfully developed, making China the third country after the United States and Japan to develop 10 trillion commercial high-performance computers.

In October 2009, China's first petascale supercomputer was unveiled in Changsha, Hunan Province, and the computer, named Tianhe-1, ranked first among the top 100 supercomputers in China announced on the same day, making China the second country in the world after the United States to be able to develop petascale supercomputers. System-wide peak performance is per second.

China's Jian-12 (Li Xiangyang in the air) fighter The Jian-12 fighter was secretly being developed by China at the end of the decade. The development plan of the Jian-12 fighter was put forward in March 1969, and in the proposal put forward by the Air Force to the Commission of Science, Technology and Industry for National Defense and the National Defense Industry Office on the national defense scientific research plan, the idea of developing a small and portable fighter plane was proposed, and the new aircraft was required to be simple in equipment, low in cost, able to fly at any time, able to fight everywhere, and able to take off and land on highways. On December 26, 1970, a prototype aircraft took off for the first time and made a successful test flight.

However, because the J-12 is the first fighter developed by China itself, and the main development time is only 1 year and 5 months, some necessary tests have not had time to be done in detail, therefore, in view of the problems existing in the test flight of the three prototypes, Lu Xiaopeng and others have made up the necessary tests, and made more than 10 major modifications to the aircraft, such as the use of area law to reduce flight resistance, reduce the reverse angle on the wing, etc., re-issued the map manufacturing, the first improved aircraft on July 1, 1975 again test flight success, From July 1975 to January 1977, the improved J-12 flew a total of 135 test sorties, 81 hours and 12 minutes. It should be said that as China's first new-type aircraft developed completely on its own after getting rid of the pattern of the Soviet MiG aircraft series, the development of the Jian-12 was successful, and the measurement and test flights have shown that the Jian-12 aircraft is by far the lightest of the world's supersonic fighters, and its geometric size and maximum cross-sectional area are the smallest among similar aircraft. Some people have summed up the outstanding characteristics of the J-12, that is, "light, short, and smart."

The so-called light, that is, the normal take-off weight of the aircraft is only 4 5 tons; The so-called short, that is, the take-off and landing distance of the aircraft are within 500 meters; The so-called spirit refers to the climbing, hovering performance and maneuverability of the aircraft, and the following performance is better than that of similar aircraft. Satisfied.

Answer]: B, C

The main engine of the giant machine is composed of high-speed computing components and a large-capacity fast main memory. Due to the large throughput of giant machining data, only the main memory is not enough, and it is generally supported by semiconductor rapid expansion memory and massive (magnetite disk) storage subsystem. The network mode can greatly improve the utilization rate of the giant machine.

Mainframes use dedicated processor instruction sets, operating systems, and application software. The term mainframe originally referred to a large computer system housed in a very large framed iron box to distinguish it from the smaller mini-computers and microcomputers. The difference between a giant computer and a mainframe is that the computing speed of a giant machine is faster than that of a mainframe, and the number of CPUs contained in a giant machine is more than that of a mainframe, not in terms of size.

Therefore, the correct options for this question are b and c.

The Jianjiao-1 aircraft is a single-engine, two-side-intake, two-seat subsonic fighter trainer developed by China's Shenyang Aircraft Industry [Group], and it is also the first jet aircraft designed and developed by China. At the end of 1957, it was put into trial production, and its first flight was successful on July 26, 1958. The successful development of the Jianjiao-1 aircraft indicates that China's aviation industry has set itself in the development stage of developing a new type of aircraft on its own.

Fighters: J-5, J-6, J-7, J-8, J-10, FC1 Thunder, J-11, J-20 Fighter Bomber: JH7 Flying Leopard.

Strike Machine: Strong Five.

Bomber: H6 H-6.

AWACS aircraft: Air Police 2000, Air Police 200

The most famous. FC1 Thunder - exported to Pakistan and participated in the Farnborough Air Exhibition.

J-10 - the aircraft with the highest number of appearances.

J-20 Air Police 2000 - the world's advanced level of large early warning aircraft.

There are J-7, J-8, J-10, J-11, J-11, J-5 and J-6 that have been retired

There are also J-15 and J-20 under development

The famous should be the J-7 J-10 and J-20 J-7 are exported in large quantities There is a complete set of series brands J-10 is a topic that has been boiling in recent years J-20 has just come out recently But it has attracted the attention of many people.

J-5, J-6, J-7, J-8, J-10, J-11, J-20 strong 5, H-6, J-7

The main forces almost saved these, among which the J-5 and J-6 were retired.

Internationally, it is noted that J-7 [sells more], J-10 [self-developed 3rd generation aircraft], J-11 [Su-27's name is known to everyone], and J-20 [3rd fourth-generation aircraft].

The internationally famous J-11 and J-10, the Air Police 2000 and the Zhi-10 armed ***.
