This paper studied a parallel algorithm of bi-cubic numerical forecast model.By using the one-dimension partition for data decomposition and drawing lessons from the transposition algorithm of block-checker board partitioning matrix,it designed and implemented the data transposition algorithm.It adopted the overlapping of computation and communication in order to reduce the influence of communication time on parallel efficiency.It implemented and evaluated the parallel algorithm of bi-cubic numerical forecast model by experiments on a cluster system.The experimental results show that the implemented parallel algorithm has high parallel efficiency;good effect is obtained by using the data transposition communication algorithm and the overlapping technology of computation and communication.
