Problems solved by technology
This kind of operation mode is acceptable in the case of solving fewer emission sources and shorter running time. However, when the number of emission sources to be considered increases and the duration of simulation increases, the computer time for single-threaded operation will increase significantly.

The invention discloses an atmospheric pollutant diffusion simulation method based on a computer cluster. A large calculation problem is decomposed into a plurality of small sub-problems according to a certain rule, the sub-problems are distributed and scheduled to different nodes of a high-performance calculation platform for calculation, large problems are decomposed into small problems for parallel calculation, so that the problem processing time can be greatly shortened. According to the method, the cross-node multi-thread parallel computing of the atmospheric pollutant diffusion model can be realized on a large computer cluster computing platform, the computing efficiency is improved, the cross-node parallel computing on the computer cluster platform can be realized under the condition that source codes of the model are not changed, and the computing efficiency is improved. Compared with single-thread calculation and single-machine multi-core parallel calculation, the calculation efficiency is further improved.
Description
technical field [0001] The invention relates to the technical field of atmospheric environment, in particular to a method for simulating the diffusion of atmospheric pollutants based on computer clusters. Background technique [0002] Atmospheric pollutant dispersion simulation is a widely used method in atmospheric environment research and air quality management. Commonly used atmospheric dispersion models include HYSPLIT, CALPUFF, AERMOD, etc. The atmospheric diffusion model realizes the prediction of the transportation, diffusion and transformation process of pollutants in the atmosphere by establishing equations describing the migration and transformation laws of pollutants in the atmosphere. Through the atmospheric diffusion model, the spatial distribution characteristics of atmospheric pollutants caused by specific emission sources can be calculated on the premise of knowing the meteorological parameter field. [0003] At present, with the deepening of urban and regio...
