An effective matrix multiplication parallel algorithm based on MPICH is designed according to the features of task communication on MPICH parallel programming environment.Divide matrix A into corresponding submatrices by line according to the quantity of process in COW (Cluster of Workstations),each process is responsible for the multiplication of a line block in A with matrix B.Experimental results show that the algorithm improves utilization of resources in cluster parallel environment as well as the operating efficiency of procedures.
