The integration of stiff, very coupled, ordinary differential equations which describe pollutant chemical reactions is the most intensive computational task of photochemical models, since it requires at least 70% of the total CPU time. As a consequence of the local nature of these equations, the integration can be performed very efficiently by a SIMD architecture. In this work we present the porting of QSSA (Quasi Steady State Approximation) chemical solver of CALGRID photochemical model on the SIMD massively parallel platform Quadrics/APE100 which offers, in QH4 configuration, a peak performance of 25 Gflops.
