For more than half a century, after the care and "nurturing" of scientists, new computer "babies" have been born one after another. Many rookies and stars have emerged, and the computer family has developed and expanded, making computers more popular. The family started from scratch, gradually matured, prospered, and gradually developed and expanded, creating colorful computer science and culture and forming a computer world that is unforgettable and exciting.
Today, the development of computer science is still in the ascendant, and the grand blueprint of the future computer world is attracting people to move towards new goals...
Supercomputer, in the modern electronic computer family Among them, it ranks first for its best performance, strongest ability and most sophisticated technology.
Today, supercomputers have become an important tool for scientists and engineers to conduct scientific research.
It is no exaggeration to say that the level of supercomputers not only reflects the level of a country’s computer technology, but also reflects the comprehensive national strength of a country. It is the pearl on the crown of computers. Due to this, all countries in the world All attach great importance to its research and development.
The original supercomputer was the world's first computer "Eniaka" built in 1946.
It was the fastest at the time: it could perform 5,000 addition operations per second.
It had the highest performance at the time: it could calculate the trajectory of the cannonball.
It was the largest at the time: covering an area of ??160 square meters.
It consumed the most electricity at the time: 150 kilowatts.
It was the most expensive at the time: the budget was as high as $150,000.
However, it was only glorious for a while and was replaced by latecomers.
At the end of 1996, the U.S. Department of Energy National Laboratory and Intel Corporation jointly announced the launch of a supercomputer capable of performing 1,000 billion operations per second. This computer, which is mainly used for simulating nuclear explosion tests, has 86 chassis and is about the size of a small room. More than 9,000 high-power Pentium processors make up its "super heart." The supercomputer weighs 44 tons, consumes 850 kilowatts of electricity, and requires 300 tons of air conditioning equipment to cool it.
Compared with the original supercomputer "Eniaka", the computing speed has increased by 2 billion times. It can be seen how amazing the development of electronic computer technology is!
Supercomputers determine a country’s economic competitiveness, because many major scientific and technological issues require the help of supercomputers, such as: developing high-performance, energy-saving cars and aircraft; more accurate Forecasting weather; predicting global climate change; improving environmental research models; improving military systems; studying how the universe was formed; designing better medical drugs; designing new materials and studying the properties of new materials; studying the structure of biomolecules, etc. wait. Therefore, in a sense, the research level depends on the computing conditions. Obviously, it is very important to vigorously develop supercomputer technology.
Supercomputer is a behemoth in the computer family, also known as supercomputer. Its computing speed and memory capacity are far ahead of other types of computers, so it must be used for work that requires a huge amount of calculations, such as complex scientific calculations.
The level of a supercomputer not only reflects the level of a country's computer technology, but also reflects a country's comprehensive national strength. It is the jewel in the crown of computers. All countries attach great importance to it. The Galaxy-I and Galaxy-II developed in our country are supercomputers.
Supercomputers are expensive, and only important scientific research and military departments use them. Therefore, the annual output in the world does not exceed a hundred units, and the number of units owned is only a few hundred units.
The characteristics of a supercomputer are firstly its fast computing speed and secondly its large memory capacity. Large memory capacity is easier to solve because memory chips are basically standard and can be mass-produced. At present, 16M (16 megabits) has been sold in large quantities, and 1G (1024 megabits) has also been successfully trial-produced.
The memory capacity of Galaxy-II is 2048MB, which is equivalent to 8X256M. It can be achieved by connecting 128 16M memory chips together. At present, the memory capacity of advanced supercomputers is above the GB level.
