Abstract

This work describes the development of a parallel communication strategy on distributed memory platforms and its application to a Navier-Stokes solver for compressible fluid flows. In the present method, distributed mes- sage passing libraries are used in order to allow inter -processor communi- cations. In particular, the implementation on the IBM-9076 SP1 available at CRS4 has been performed using the native IBM message-passing library [3] in order to enhance the usage of the inter-processor switch. 1 Introduction Computational Fluid Dynamics (CFD) has reached a certain degree of maturity and numerical methods based on the solution of the Reynolds- averaged Navier-Stokes equations are widely used for the simulation of tur- bulent compressible flows. However, such simulations are computationally intensive and require the use of modern su
