Matrix Multiplication with MPI

For two matrices, A (400x500) and B (500x300), the multiplication operation performed 500 times. The below is the result of execution time by using various processors.

1 Processor --> 89.54 seconds

mpiexec -np 1 ./MPI_Matrix_Multiplication 500 400 500 300

4 Processors --> 27.62 seconds

mpiexec -np 4 ./MPI_Matrix_Multiplication 500 400 500 300

10 Processors --> 16.58 seconds

mpiexec -np 10 ./MPI_Matrix_Multiplication 500 400 500 300
