Solving three-dimensional transport models with synchronous and asynchronous iterative algorithms in a grid computing environment

In this paper we study the development of parallel algorithms to solve advection-diffusion equations. Both synchronous and asynchronous algorithms contexts are considered. The solver we present is based on the multisplitting Newton method that provides a coarse-grained scheme. Experiments are carried out in an heterogeneous grid environment in which both parallel algorithms are analyzed. Experiments allow us to draw some conclusions about the use of parallel iterative algorithms in a grid computing environment.
