摘要
将Decell算法与MPI并行系统进行有效结合,用于计算大规模矩阵的MP广义逆.给出了算法设计方案;讨论了在MPI环境下的程序执行;并在PC机集群系统上实现.给出了关于并行加速比及效率的数值结果.
The paper tried to combine Decell method and the MPI system to calculate the generalized inverse of matrices of large dimension. New algorithm was given, and its realization on a PC local network system was described. Experimental results showed that the speed and efficiency of the new algorithm is much better than common serial algorithms.
