Question 02: The following table shows the execution times, in seconds, for five different benchmark programs on three machines. Processor Benchmark R M Z E 417 244 134 F 83 70 70 H 66 153 135 I K 39,449 35,527 66,000 772 368 369 a. Compute the speed metric for each processor for each benchmark, normalized to machine R. That is, the ratio values for R are all 1.0. Other ratios are calculated using Equation (A) with R treated as the reference system. Then compute the arithmetic mean value for each system. b. Repeat part (a) using M as the reference machine. c. Which machine is the slowest based on each of the preceding two calculations? d. Repeat the calculations of parts (a) and (b) using the geometric mean. Which machine is the slowest based on the two calculations? Related Information for Solving Question 2: The speed metric measures the ability of a computer to complete a single task. SPEC (Standard Performance Evaluation Corporation) defines a base runtime for each benchmark program using a reference machine. Results for a system under test are reported as the ratio of the reference run time to the system run time. The ratio is calculated as follows: ri = Trefi Tsuti (A) where Tref¡ is the execution time of benchmark program i on the reference system and Tsut, is the execution time of benchmark program i on the system under test.
