Computer architects can’t agree on a way to find the average. For years, academic practitioners in this field have been arguing about the appropriate way to summarize the average performance of their designs.1 That is: given \(n\) workloads, if system \(A\) outperforms system \(B\) by \(S_1, S_2, \ldots, S_n\) on each, how much faster should you say system \(A\) is, on average? I think this argument is kind of pointless through. For the most part, people tend to use the arithmetic mean \(\left(\...
