Description:

The objective of this project is to develop a high performance coupled hydrodynamics-water quality model, based on an existing hydrodynamics-water model developed by Sheng and to-be-developed reusable object-model-based class libraries for parallel numerical solvers and science processes related to cross-media modeling and uncertainty. The 3-D hydrodynamics-water quality model developed by Sheng will be modularized to allow parallelization with ease. Each module of the modularized model will be improved with parallel techniques and tested on a number of computing environments, including MasPar2, SGI Origin 2000, CRAY T-3D, and SUN-UltraSPARCS connected with PVM. These parallel algorithms will be compared, improved, and stored in a library which can be accessed via Internet by EPA scientists and grantees. The parallelized 3-D hydrodynamics-water quality model will be applied to Florida Bay, a complex ecosystem.
