Abstract

Parallel performance and benchmarking of the CE-QUAL-ICM family of three-dimensional water quality models Mark R. Noel*, Terry K. Gerald^, and Carl F. Cerco^ *AScI Corporation, U.S.A. ^AScI Corporation, U.S.A. U.S. Army Engineer Research and Development Center, U.S.A. Abstract Accurate analyses of water quality issues pertaining to waterways require the application of eutrophication and contaminant transport/fate models to evaluate management alternatives. The movement of models to scalable, parallel computing platforms is a necessity since these simulations exhaust the resources of single processor computing systems. The CE-QUAL-ICM family of three-dimensional water quality models, developed at the U.S. Army Engineer Research and Development Center Waterways Experiment Station (WES), Vicksburg, MS, consists of an eutrophication model (ICM) and a transport/fate model (ICM/TOXI). Both codes were parallelized by combining a single program multiple data (SPMD) execution m
