PVM 环境下提高并行计算加速比的数值实验研究

NUMERICAL RESEARCH OF RAISING SPEEDUP OF PARALLEL CALCULATION ON PVM

通过采用区域分割技术和拼接网络的方法，在ＰＶＭ并行环境下，对三维高超音速绕流流场进行了多机并行计算，得到了较高的加速比。通过数值实验研究，讨论了负载平衡、不同的网格规模对加速比的影响。

In this paper,used the domain decomposition technique (DDT) and patched grid,Parallel numerical calculation with TVD implicit finite volume algorithm is carried for 3D hypersonic viscous flowfield on PVM.The high speedup is obtained,and the influnce of blancing load,different grid scale to the speedup is discussed.
