Abstract

Studying high pollution levels in different regions of Europe is an important environmental problem. Large mathematical models can successfully be used in the treatment of this problem. However, the use of large mathematical models in which all physical and chemical processes are adequately described leads, after the application of appropriate discretization and splitting procedures, to the treatment of huge computational tasks: in a typical simulation one has to perform several hundred runs, in each of these run one has to carry out several thousand time-steps and at each time-step one has to solve numerically systems of ODE's containing up to O(106) equations. Therefore, it is difficult to treat numerically such large mathematical models even when modern computers are available. Runs of an important module of a large-scale air pollution model on parallel message passing machines will be discussed in this paper. Numerical results will be presented.
