Parallizing 1-dimensional estuarine model
Wave simulation is an important problem in engineering. Wave simulation models play significant roles in environmental protection. Wave simulations have thus far been done mostly serially. In order to meet the demand for increased spatial and temporal resolution and uncertainty analysis in environmental models for ecological assessments and water resource managements, it is essential to develop high-performance hydrodynamics and water quality models using parallel techniques. In this paper, algorithms for parallelizing 1-D wave simulation models are proposed. In particular, we introduce a paradigm called LessTalk for reducing communication costs in parallel computing. Our wave models have been implemented using Parallel Virtual Machine (PVM) and Multithreading. The experiments show that these algorithms that employ LessTalk are efficient and the parallel wave simulation models have excellent speedup performances.
