Based on the Greville algorithm and Gaussian row pivot elimination,we worked out the method of computing Moore-Penrose generalized inverse matrix,analyzed the complexity of it (i.e (O(mn2/p)),the cost of the parallel computing ((O(mn2)).speed-up ratio and efficiency,discussed how to programming with the message passing interface (MPI),parallel computing in the PC network system under Linux,and list some computational results at last.
