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。
In order to solve the problem of slow speed and small storage capacity of single-processor computer in the whole system transient flow calculation of large-scale water conservancy and hydropower projects, based on the analysis of the parallelism of the whole system transient flow calculation in large hydroelectric projects, The whole system transient flow parallel computing model. Taking a large-scale water diversion project as an example, the task of parallel computing is divided according to the principle of load balancing, and the message passing parallel programming mode is adopted. When using two computers in parallel computing, the calculated speedup reached 1.442, and the parallel and serial calculations the same.
