Abstract

The efficiency and the scalability of a successful parallel implementation of a 3D trans- port model for coastal seas is presented. The work is concentrated on the evaluation of the parallelism of the iterative solver after implementing several High Performance Computing techniques. Thus, the impact of a block variant of the ELU preconditioner proposed to avoid the inherent sequentiality of this step is measured. This variant was obtained by a spectral bisection technique which is used to partition the FEM mesh. Consequently, each submesh corresponds to
