Parallel Computation of Multidimensional Polynomials in State Equation of Seawater

Abstract

The computation of the standard formulation of the International Association for the Properties of Water and Steam for seawater requires the evaluation of some multidimensional polynomials to obtain the thermodynamical properties useful in industrial processes as desalination and in the massive simulation of the oceans. These polynomials are related to the Gibbs free energy function and its first and second derivatives. A computational model to parallelize the evaluation of those polynomials is proposed by using both vector and multicore parallelization. In the implementations carried out, the combined performance of both paradigms generates significant speed-up. The interest of this paper for the general scientific community lies in the fact that future simulations that achieve the exact model of that standard for seawater will require efficient programming of these equations.
