Abstract

The aim of this work is to provide a high performance air quality simulation using the STEM-II (Sulphur Transport Eulerian Model 2) program, a large pollution modelling application. The execution of the sequential program on a workstation requires significant CPU time and memory resources. Thus, in order to reduce the computational cost, we have applied parallelization techniques to the most costly parts of the original source code. Experimental results on a 32-processor SGI Origin 2000 show that the parallel program achieves important reductions in the execution times. This will allow us to obtain results in valid response times and with the adequate reliability for the industrial environment where it is intended to be applied.
