Where are supercomputers widely used?

Supercomputers are widely used in the following aspects:

1, weather forecast

Supercomputers play an important role in weather forecast. Through the actual atmospheric data observed by remote sensing satellites, the supercomputer can solve the dynamic equations describing the weather evolution process and realize the numerical calculation of short-and medium-term weather forecast. For example, the computing power of the ibm systemp575 supercomputer used in the 2008 Beijing Olympic Games is 10 times that of the existing system.

It can cover an area of 44,000 square kilometers and provide air volume and air quality forecast per square kilometer per hour. Supercomputer's high-performance computing ability can accurately simulate and observe the movement of clouds, improve the observation accuracy, and provide accurate data support for climate change prediction.

2, materials science and calculation

Supercomputers are widely used in materials science and calculation. Nanotechnology makes the simulation calculation of matter and energy intensive, thus accelerating the process of scientific research. Scientists use supercomputers to simulate various scientific problems, such as the development of anticancer drugs, the simulation of the earth's climate, and the simulation of the universe and galaxies.

Supercomputers can greatly speed up these studies and make researchers spend less time on experimental results.

3. Petroleum exploration

In oil exploration, supercomputers can be used to calculate the location of drilling. Seismic exploration uses the elastic difference and density difference of underground medium to observe and analyze the response of the earth to artificially excited seismic waves, infer the nature and shape of underground strata, and thus determine the accurate distribution of oil and gas. Supercomputers can quickly calculate, process and analyze a large number of numerical data.

Converted into intuitive three-dimensional images, providing key technical support for oil exploration. For example, Shuguang 4000L supercomputer played a key role in Nanbao Oilfield with a reserve of 1 100 million tons in Bohai Bay, and the application of Shuguang 5000A supercomputer further reached the exploration depth of several kilometers underground.
