Description
Summary:A barotropic quasigeostrophic finite element model of regional ocean circulation is implemented on three parallel architectures: a Multiple Instruction Multiple Data (MIMD) vector computer, a Single Instruction Multiple Data (SIMD) Hypercube and a network of workstations connected together using Fiber Distributed Data Interface (FDDI). Specific computationintensive tasks are identified and alternative algorithms are implemented and compared. Detailed performance comparisons are presented. Issues in parallel algorithm design, such as portability, scalability and efficiency, are studied in an attempt to provide guidance to numerical modellers wishing to use parallel and distributed computing. The first intended application is the analysis of the meandering of the Kuroshio, an intense current in the North Pacific which is the dynamical analog of the Gulf Stream in the North Atlantic. Here we consider the distinctive eddy patterns off the coast of Japan. The model reproduces the.
