Parallelisation of hydro-environmental model for simulating marine current devices

There are many serial simulation codes in the geosciences that cannot take advantage of the computational resources commonly available today. Further, the initial design of many parallel application codes targeted relatively small-scale commodity clusters and does not take full advantage of modern cache-based, blade computing system. In this paper, we discuss the porting of a widely used hydro-environmental code, EFDC, to parallel using both the MPI and OpenMP paradigms. The objective of the research is to better elucidate the strengths and weaknesses of both approaches to further a hybrid parallelisation strategy that leverages the capabilities of both.
