Consider a matrix-vector multiplication using a distribution of the linear combinations based on a column-wise distribution

Consider a matrix-vector multiplication using a distribution of the linear combinations based on a column-wise distribution of the matrix. Transform the pseudo program from figure 3.13 page 146, to a running MPI program. Use appropriate MPI operations for the single-accumulation and single-broadcast operations. Compare the execution time with the execution time of the MPI program from the preceding exercise for different sizes of the matrix.
