Numerical Weather Prediction Semi-lagrangian Time Integration Algorithm And Its Parallel Realization

Based on the basic theories in the high perforemance parallel computation, a superposition boundary optimal model about the framework of distrabuted shared memory parallel multi-computer is proposed. Taking the ocean circumfluence model as a numerical example, under highly computational precision is achieved, parallel efficiency is improved greatly by choosing suitable boundary number of the proposed model.Further more, interpolation algorithm called semi-Lagrange time intergration model (including bi-linear, quasi-cubic and cascade interpolation) are analysed, its distributed shared memory parallel computation is implemented. Numerical experimentations show the parallel efficiency is satisfactory.Finally, analysis and research are taken in the external interface of Numerical Weather Prdiction-post-processing, and further work is discarsed.
