Matrix-Matrix Multiplication MPI C Source Code

Expanding from my previous post, “Matrix-Vector Multiplication MPI C Source Code”. Now we create a program to calculate two two-dimensional matrices (array) with MPI. Same concept and algorithm with matrix-vector used to solve this problem, row-based operation.

Now the differences from matrix-vector just the array size and dimension.

#define AROW 3
#define ACOL 2

#define BCOL 3

#define MAX_VALUE 10

For proc_map() function please look at matrix-vector post, and here’s the computational code for matrix-matrix multiplication.
