Parallel Efficiency of a Boundary Integral Equation Method for Nonlinear Water Waves

摘要

We describe the application of domain decomposition an a boundary integral method for the study of nonlinear surface waves on water in a test case for which the domain decomposition approach is an important tool to reduce the computational effort. An important aspect is the determination of the optimum number of domains for a given parallel architecture. Previous work on heterogenerous clusters of workstations is extended to (dedicated) parallel platforms. For these systems a better indication of the parallel performance of the domain decomposition method is obtained because of the absence of varying speed of the procesisng elements.
