Load Balancing for the Numerical Solution of the Navier-Stokes Equations
Overview This paper simulates the performance of a load balancing scheme. In particular, it studies the application of the Extrapolated DiFfusion (EDF) method for the efficient parallelization of a simple 'atmospheric' model, which involves the numerical solution of the steady state Navier-Stokes (NS) equations in the horizontal plane and random load values, corresponding to the "Physics" computations, in the vertical plane. For the numerical solution of NS equations the Local Modified Successive OverRelaxation (LMSOR) method is used with local parameters thus avoiding the additional cost caused by the global communication of the involved parameter ù in the classical SOR method. An efficient domain decomposition technique is implemented by using a larger number of processors in the areas of the domain with heavier work load.
