Four benchmark programs are executed on three computers with the following results: Program 1 Program 2 Program 3 Program 4 Computer A 1 1,000 500 100 Computer B 10 1000 1,000 7,000 Computer C 20 200 120 100 The table shows the execution time in seconds, with 100,000,000 instructions executed in each of the four programs. Calculate the MIPS values for each computer for each program. Then calculate the arithmetic and harmonic means assuming equal weights for the four programs, and rank the computers based on arithmetic mean and harmonic mean
