3. Given the following performance of two programs on three CPUs, use the geometric mean to calculate performance: CPU A CPUB CPU C Program P, (secs.) 40 15 20 Program P, (secs.) 40 1000 150 Which computer is faster? 4. Computers A and B implement the same ISA. Computer A has a clock cycle time of 250 ps and an effective CPI of 2.0 for some program and computer B has a clock cycle time of 500 ps and an effective CPI of 1.2 for the same program. Which computer is faster and by how much? -- show your work here
