Industrial Application of Changsha Center of National Supercomputing

Changsha Supercomputing Center will make the weather forecast more detailed.

"The mesoscale numerical prediction model with an operating area of 2.72 million square kilometers and a grid spacing of 4 kilometers only takes 50 minutes, which is completely impossible on computers with 23 million calculations per second in the past." In the network room of Hunan Meteorological Disaster Prevention and Mitigation Early Warning Center, Yin Xinhuai, deputy director of the Provincial Meteorological Observatory, told reporters that the Provincial Meteorological Bureau has put AREM and WRF two mesoscale models into trial operation in the National Supercomputing Center.

On July 10, the first phase of the mainframe system of the National Supercomputing Changsha Center was completed and opened, officially providing computing services to the society. This is the second national supercomputing center in China after Tianjin. The Provincial Meteorological Bureau has become the first public user of Tianhe-1, and the high-performance computer will improve the calculation ability of the numerical forecast model, providing strong technical support for the high-resolution disastrous weather forecast and the refined "seamless" forecast in Hunan.

After the calculation, saving money is not a little bit.

Liu Hong, director of the Department of Computing, School of Mathematics and Computer Science, Hunan Normal University, said that the communication bandwidth of Tianhe No.1 is 40GB per second, which is equivalent to downloading five high-definition movies in 1 second; From simulation design, medical research and development to typhoon prediction and energy survey, it has its uses.

Liu Hong believes that supercomputing is suitable for fine scientific calculation of large-scale computing arrays. For example, the National Supercomputer Tianjin Center used the "Tianhe No.1" supercomputer to build an oil exploration data processing platform to accurately calculate the location and reserves of oil wells. The exploration cost of each oil well is as high as tens of millions of yuan. As you can imagine, using super-calculation to locate accurately can save costs.
