Abstract:

We present a tool to get already existing sequential software for solving PDEs to work on shared and distributed memory supercomputers in a reasonable amount of time. The library uses a physical partitioning of the initial computational domain. Issues on the approaches used for implicit and explicit schemes are presented. Finally, real examples are given for 3 codes that currently use the tool: a full blown FEM code for solving the turbulent compressible Navier-Strokes equations, a linear acoustic solver for 3D problems based on spectral FEM and a Discontinuous Galerkin code for the Euler equations.
