Numerical Simulation of 3D Fully
Nonlinear Water Waves on Parallel Computers
Department of Informatics, University of Oslo
Abstract
A new programming
model is used to parallelize a sequential simulator for 3D fully
nonlinear water waves. This so-called simulator-parallel model has its
numerical foundation in additive Schwarz methods, so it possesses
inherent parallelism and inherits the intrinsic numerical
efficiency of domain decomposition algorithms.
Within an object-oriented framework
implementing this model, the actual parallelization work for the
sequential wave simulator becomes straightforward. Numerical
experiments show that the resulting parallel simulator achieves good
parallel efficiency.
