The total amount of work done in a given time. The table below shows the execution times for two programs on two machines. Use the table in problem 21 and the table below. Machine M1 has a clock rate of 500 MHz, and machine M2 has a clock rate of 800 MHz. Assume the CPI for program 2 on each machine is the same as for program 1, calculated in problem 24.
Larger numbers indicate more cost effectiveness.
1.02 times more cost effective than M1. Consider the table in problem 26. Program 1 must run 200 times each hour, and program 2 may run as many times as possible in the remaining time.
