This is the code we change. <br />
- First we change to header to allow Cilk Plus. <br />
- Second we comment the bad slow method from "initialize_2D_buffer" and use the faster method. <br />
- Third we add some Cilk Plus code to make it the program run in parallel.
<br />
If we go to bottom up tab you can see that the "initialize_2D_buffer" is no longer exist and it shows the Cilk worker graph that shows the program is not run a parallel.
