matrix_vector_openmp.c:

This file is the openmp version of matrix vector multiplication. the dimentions are hardcoded as macro. so changing will require a recompilation. the serial version is also embedded inside the code to compare the performance of serial to parallel execution on same matrix. The timers are given and if the dimention of the result matrix is larger than 16 the result will not be printed instead the timers will be printed. as both matrices are initialize to all 1's the result will always be a vector with each element is equal to its number of columns of the first matrix or the dimention of the vector.
