When did Tianhe No.1 win the top 500 championship for the first time?
Tianhe-1 is the first gigabit supercomputer in China. Tianhe-1 supercomputer was developed in 2008 and implemented in two stages. The first phase system was successfully developed in September 2009. The second phase of the system was upgraded in the National Supercomputing Tianjin Center on August 20 10.
On 2010165438+10/4, the international TOP500 organization published the latest list of the top 500 global supercomputers on its website, and Tianhe-1, the first gigabit supercomputer system in China, ranked first in the world. Then it was surpassed by Japanese supercomputer Jing in 20 1 1 year. 20 12, 18 On June 8, 2008, Tianhe No.1 ranked fifth in the list of the top 500 supercomputers in the world published by the International Supercomputer Organization.
After Tianhe-1 was put into use in 20 10, it has made remarkable achievements in space flight, weather forecast, climate forecast and marine environment simulation. China will use supercomputer technology to monitor smog weather.
The scientific research significance of Tianhe-1;
The birth of Tianhe-1 is another major innovation in the research and development of strategic high-tech and large-scale basic scientific and technological equipment in China, which has achieved a leap in China's ability to independently develop supercomputers from 100 megabytes to gigahertz, making China the second country in the world to develop gigahertz supercomputer systems after the United States.
Tianhe No.1 has broken through a series of key technologies, such as multi-array configurable collaborative parallel architecture, high-speed scalable interconnection communication, efficient heterogeneous collaborative computing, security control based on isolation, virtual network computing support, multi-level fault tolerance of large-scale systems, and comprehensive control of system energy consumption.
The peak performance of Tianhe-1 system reaches 1.206 trillion double-precision floating-point operations per second, with total memory capacity of 98TB, peer-to-peer communication bandwidth of 40Gb per second and disk capacity of 1 PB. It has the remarkable characteristics of high performance, high energy efficiency, high safety and ease of use, and its comprehensive technical level has entered the forefront of the world.
