A student asked me further help for the 4.b exercise. This is my answer:
Both the slides and the book explain to us how to use a reference
machine with different types of mean. The 4.b exercise asks you: " You
wonder how the performance of the three machines would compare using
other means to normalize performance. Which machine is faster by the
You have also the information that you need to use the geometric mean
(GM(R) is asked for R=A, B, and C). The book and our conversations in
class outlined the straight of the geometric mean. The slides in our
lectures showed us how to compute it. The exercise mainly is asking
you to take the geometric mean of the execution times and use the
inverse to identify the faster machine.
I hope this helps you.
