| High performance simulator for emission control and immission forecasting for the Austrian city of Salzburg. The project required to simulate the impact on ground pollution of the emissions of approximately 600 single sources and of 1,000 area sources. The impact on 76,000 points of the city´s territory was calculated for each half an hour of the year, i.e. for 17,500 meteorological situations The computing had to be performed in two steps; first, to compute the base immission situation (data base) for a complete reference year. Secondly, it is frequently used for urban development decisions, to evaluate the expected impact of new emittents under selected meteorological conditions. | High performance simulator for emission control and immission forecasting for the Austrian city of Salzburg.

| The estimated time for computing the immission data base on a standard mainframe computer in 1988 was 2.5 years. This could be reduced with the delivered simulator (parallel computing hardware) to about 14 days. The impact of new emittents in a specific meteorological situation could be computed within half a second. Due to this excellent performance, | The estimated time for computing the immission data base on a standard mainframe computer in 1988 was 2.5 years.
