Abstract: 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.

Key words: generalized inverse, MPI system, parallel computing, generalized inverse, MPI system
