✦ Synopsis

In this work we present a subdomain partitioning strategy applied to an explicit high-resolution Euler solver. We describe the design

The subdomain partitioning strategy adopted in this of a portable parallel multi-domain code suitable for parallel enviwork is a special case of the more general multiblock techronments. We present several implementations on a representative nique where the grid is divided into several blocks linked range of MIMD computers that include shared memory multiprocesby appropriate internal boundary conditions. In the field sors, distributed virtual shared memory computers, as well as netof computational fluid dynamics (CFD) applications the works of workstations. Computational results are given to illustrate advantages of such an approach are multiple: it provides the efficiency, the scalability, and the limitations of the different approaches. We discuss also the effect of the communication protoa way to adapt a structured grid to complicated geometries col on the optimal domain partitioning strategy for the distributed yielding better results in terms of convergence rates and memory computers.
