主要还是让A(i,j) B(i,j)进行移动A(i,i+j),B(i+j,j)，然后进能直接相乘。具体的内容可以看并行算法导论，-Matrix multiplication with the Cannon Algorithm:

The Cannon Algorithm for matrix multiplication was presented in the course “Parallel and Distributed

Algorithms “by Dr. Klauck.

Short descr iption:

The matrices A and B are stored in files. The file names have to be specified as parameter. The root

process reads the matrices and distributes the respective values to all processes, so that processor i, j

has the values ai,j and bi,j.
