# Assignment 3: Benchmark analysis

Due: 5:00pm, Thu 7 Feb. Value: 40 pts. Submit to Moodle.

Altogether there were nine solutions to Assignment 1. The following table summarizes the last four numbers reported in the assignment: the ratio of grendel or ozark to a lab computer on each of the two benchmark programs. The graph at right plots the relative performance of grendel and ozark according to each solution, measured as the geometric mean of the two ratios for each computer.

 Primality Gaussian grendel ozark grendel ozark Solution A 1.70 2.59 2.17 3.15 Solution B 0.33 1.00 3.72 2.37 Solution C 4.34 7.69 2.89 2.18 Solution D 2.62 2.19 2.40 1.60 Solution E 0.00 0.00 5.92 4.80 Solution F 3.40 6.25 2.34 1.77 Solution G 0.00 0.00 1.00 1.75 Solution H 2.33 2.67 3.28 4.97 Solution I 0.54 0.85 2.33 1.59 Surprisingly, there is quite a bit of variety. That's a good indicator that most of these have some major problems!

I've randomly assigned three of these solutions for you to review, as shown below. (If you work with another student on this assignment, use the following algorithm: Let X be the person whose last name comes earlier in the alphabet, and let Y be the other person. You should review the three solutions assigned to X. But if Y's solution to Assignment 1 is included on X's list, then you should replace Y's solution with any one of the solutions assigned to Y — but do not choose X's solution to Assignment 1, and of course do not choose a solution already appearing on X's list. If that proves impossible, please contact me.)
