A parallel multi-block Navier-Stokes solver on distributed memory machines

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 message passing libraries are used in order to allow inter-processor communications. 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.
