Performance and Portability of an Air Quality Model

Abstract We present a portable, parallel implementation of an urban air quality model. The parallel model runs on the Intel Delta, Intel Paragon, IBM SP2, and Cray T3D, using a variety of standard communication libraries. We analyze the performance of the air quality model on these platforms based on a model derived from the parallel communication behavior and sequential execution time of the air quality model. We predict the performance of the next generation air quality models based on this analysis.
