摘　　要：为了解决采用单处理器计算机进行大型水利水电工程全系统瞬变流计算时速度慢和存储量小的问题,在对大型水利水电工程全系统瞬变流计算的并行性进行分析的基础上,建立了全系统瞬变流并行计算的模型。以某大型引水工程为例,根据负载平衡的原则划分并行计算任务,采用消息传递并行编程模式,通过调用M P I库函数实现并行计算部分间的消息传递。当使用两台计算机并行计算时,计算的加速比达到1.442,且并行和串行计算结果相同。With single processor computers, transient simulations of the flow in large hydraulic systems are very limited by the computer＇s speed and memory. Therefore, parallel processors are frequently used for transient flow computations in large systems. A parallel processor program was developed to analyze hydraulic flow problems with the MPI library functions called to pass messages. The parallel transient flow computations for a large diversion project have an accelerator factor of 1. 442 with two computers with the results the same as using a serial computation.
