Cannon's algorithm
In computer science, Cannon's algorithm is a distributed algorithm for matrix multiplication for two-dimensional meshes first described in 1969 by Lynn Elliot Cannon.[1][2]
It is especially suitable for computers laid out in an N × N mesh.[3] While Cannon's algorithm works well in homogeneous 2D grids, extending it to heterogeneous 2D grids has been proven to be difficult.[4]
The main advantage of the algorithm is that its storage requirements remain constant and are independent of the number of processors [2].
