Four benchmark programs are executed on three computers with the following results:

The table shows the execution time in seconds, with 100,000,000 instructions execut- ed 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.
