Parallelization of the STEM-II Air Quality Model

摘要

STEM-II is an Eulerian numerical model to simulate the behavior of pollutant factors in the air. In this paper the computational requirements of the program in terms of memory storage and execution times are analyzed. The results of this analysis are conclusive as regards to the need of using parallel processing to achieve reasonable execution times. Then, the improvements achieved after the parallelization of the code on a distributed memory multiprocessor using the MPI standard message passing library are shown.
