Your matrix is n rows by m columns. When you distribute this matrix to n processes, each process has to process m elements, but instead you use a count of n in all your vector calls. You should pass a length of m in: the find_max and find_min calls. Note that you have correctly declared receive_buffer, partial_max, partial_min to be ...Welcome to the MPI tutorials!
