LU Lin-sheng · Journal of Information Engineering University · 2005
This paper mainly discusses some general parallel methods summarized from CFD parallel computing.First,we give the partition strategy of singular area and provide the static load balancing algorithm of multi-area partition.Then in the solution to linear recursive equations,we analyse the unsteadiness problem caused by incomplete LU decomposition of the current method and introduce some iteration methods to increase the stability of solution.Furthermore,to implement the strict implicit schemes solution,we present a pipeline parallel implementing algorithm based upon pipeline relationship directional graph which can be applied in the parallel solution to recursive equations for some complicated area problems.The experimental results show that these algorithms are effective.
