摘　　要：为了能够更高效的提高胶州湾水质预报系统的运行速度,在原有基于串行模式的预报系统中引入了消息传递接口MPI(message-passing interface)并行处理技术,并在该系统中分别采用组通信模式和非阻塞通信模式,把整个水质预报系统分解为多个子任务,在基于MPI消息传递模式的集群系统中分别进行运算,通过实验表明了两种通信模式在运算速度上的差异,在预报系统中非阻塞通信模式比组通信模式更加优化。因此,非阻塞通信模式对水质预报模式的改进具有很大的潜力。For more highly effective enhancing the running rate of the water quality forecast model of Jiaozhou bay, parallel pro-cessing technology in serial mode forecast system is introduced. The paper is proposed a parallel algorithm based on the MPI is proposed. A group communication mode and a non-blocking communication mode are used respectively, and the material trans- portation＇ s question is decomposed into many sub-duties, and calculates on the model of MPI message cluster system. Finally the experiment proves the difference in the speed of operation of the two modes of communication. The result indicats that Non-bloc-king communication mode is superior to group communication mode. Therefore, non-blocking communication mode has great potential to improve water quality forecast model.
