We are using MPI code for this project. I have a general idea of what I need to do but dont fully understand it.

a) Write a program that calculates the time needed to send n messages that contain one double number each, from process 0 to process 1. b) Write a program that calculates the time needed to send 1 message that contains n double numbers, from process 0 to process 1. c) Compare the times of (a) and (b n should be given by the command line e.g. mpiexec -n 2 /program
