Question

The following table shows results for SPEC2006 benchmark programs running on an AMD Barcelona.

   name           Intr.count x 10^9         Execution time (seconds)                      Reference Time (seconds)

a.    perl              2118                                     500                                                             9770

b.    mcf               336                                      1200                                                           9120

a.    Find the CPI if the clock cycle time is 0.333 ns.

b.   Find the SPEC ratio.

c.   For those two benchmarks, find the geometric mean.

Explanation / Answer

Geometric mean = spec ratio of A/spec ratio of B

Geometric mean = (9770/2118)/(9120/336) = 0.16
