| Abstract: | In this paper an analytical mathematical model suitable for numerical weather prediction models is developed. Actual computations are performed on HLAFS, a mesoscale grid point NWP model developed in China. On the IBM RS6000 SP, The forecast model is parallelized using the hybrid MPI/OpenMP programming method, in combination with various domain partition techniques. The obtained results are analyzed and found to be in good agreement with the analytical performance model. |
