Write Myscatter.c, Mygather.c, Myallgather.c programs and compare MPI scatter functions with your own scatter, own gather, own all gather functions. From the program, collect the time it takes to execute both MPI functions and your functions. Run the program with a different number of processes: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and 24. Plot the graph (time vs # of processes) for each program. detailed description of every step is required this all code must be written in c.
