用MPI实现wave程序并行化，采用非阻塞方式-Wave process with MPI parallel implementation, using non-blocking mode

linux环境下，并行矩阵乘Cannon算法的两种MPI程序实现：采用阻塞操作与采用非阻塞操作！-linux environment, two kinds of MPI programs parallel matrix multiplication Cannon algorithm to achieve: a blocking operation using non-blocking operation!
