Zusammenfassung:This paper outlines the MPI+OpenMP programming model, and implements the matrix multiplication based on rowwise and columnwise block-striped decomposition of the matrices with MPI+OpenMP programming model in the multi-core cluster system. Experimental results show that the running time of the parallel algorithm is reduced significantly. By further analyzing the running results, the running time is reduced obviously once again.
