Lab attendance is your responsibility. Before you leave this and all future labs you must ensure that your name is on one of the check-in sheets. You will no longer be given credit if your name can not be found on one of those sheets.

Matrix Multiply

Download the lab12.zip code. Implement the missing matrix multiplication code. Edit your Makefile to use your OpenMP-capable compiler and run make. Once you have completed your implementation, you can time your program by using the time command like so: time ./mult.

Insert OpenMP Code

Insert your OpenMP #pragmas above the inner-most for loop. Gather timings on your code again. Was it what you were expecting?

More OpenMP

Now insert another #pragma above the middle for loop. Gather more timings. What happened? What if you remove the #pragma from the inner-most for loop but leave the middle loop #pragma alone?
