| Abstract: | First summarizes the differences on principle between two kinds of parallel algorithm of matrix-vector multiplication,namely,divided by row and divided by column.Based on these two algorithms,implements two programs accordingly using the MPI model and analyzes differences on the frame of these two programs.In the end,puts forward the condition and task of the experiment which purpose is to test these two programs and analyzes the executing time under diverse circumstances. |
