Problem
Consider the interleaved execution of the four programs in each of the three machines. Each program is executed in a particular mode with the measured MIPS rating.
(a) Determine the arithmetic mean execution time per instruction for each machine executing the combined workload. assuming equal weights for the four programs.
(b) Determine the harmonic mean MIPS rate of each machine.
(c) Rank the machines based on the harmonic mean performance. Compare this ranking with that obtained.
