英文摘要	A parallel algorithm of circulation numerical model based on message passing interface (MPI) is developed using serialization and an irregular rectangle decomposition scheme. Neighboring point exchange strategy (NPES) is adopted to further enhance the computational efficiency. Two experiments are conducted on HP C7000 Blade System, the numerical results show that the parallel version with NPES (PVN) produces higher efficiency than the original parallel version (PV). The PVN achieves parallel efficiency in excess of 0.9 in the second experiment when the number of processors increases to 100, while the efficiency of PV decreases to 0.39 rapidly. The PVN of ocean circulation model is used in a fine-resolution regional simulation, which produces better results. The capability of universal implementation of this algorithm makes it applicable in many other ocean models potentially.
