Abstract :
Describes a performance model for a parallel program that solves the nonlinear shallow water equations using the spectral transform method. The model is generated via a phase analysis, and consists of a sequence of simple models whose sum describes the performance of the entire code. This use of a sequence of simple models increases the range of validity of the model as the problem and machine parameters scale
