Research on the Global Spectral Parallel Computing of Numerical Weather Forecasting

The paper first introduces the governing equations of the global spectral weather forecasting model, and then gives a parallel algorithm based on 2-D data partition by means of both the computational complexity of the global spectral model and the total correlation of spectral coefficients. Considering load balancing,communication latency reduction as well as cache and I/O optimization, we present a parallelization strategy.
