OpenMP parallelization of a CFD code for multicore computers: Analysis and comparison

Abstract

In this paper we present a parallelization method for numerical simulation of incompressible flows in regular domains on multicore computers in frame of the OpenMP programming model. The method is based on natural splitting of a computational domain for the main part of the algorithm, and on two-dimensional splitting and application of a special tridiagonal parallelization procedure for pressure Poisson equation and other implicit parts. This method is suitable for running on shared memory computer systems with non-uniform memory and demonstrates good parallelization efficiency for up to 16 threads. © 2011 Springer-Verlag Berlin Heidelberg.
