• Why was this performance achieved? (Review the information about dgemm and mydgemm for the answer)

• Why is the performance of dgemm worse than that of mydgemm? (mydgemm extracts the core of dgemm to make it somewhat simpler to understand. In doing so it throws away the parts of dgemm which are generic and applicable to any size matrix. Since mydgemm cannot handle arbitrary size matrices it is somewhat faster than dgemm but less useful).

• When you are done with this exercise, please make clean to remove the executable and object files.
