摘要
首先介绍了基于PVM的网络并行计算环境,以及在win32的环境下进行PVM并行程序设计的方法。重点讨论了PVM的任务分配方法和负载平衡问题,提出了一种以计算能力的大小来动态分配任务的策略,避免了因个别计算机的低性能而影响了整个并行计算系统的加速比。实验结果表明这种策略实现简单,并且效果理想。
The paper introduce a Network Parallel Computing based on PVM platform, and the methods of parallel programming based on it. It also discusses the Tasks Distributed and Loading Balancing. Give a new dynamic task distributed strategy, which tasks distribute based on the computer performance. It works well in the experiment.
