QUESTION 1

A double precision DAXPY benchmark is being run on a 3GHz Intel CPU system which has a single issue, scalar pipeline with 14 stages. The typical, or nominally observed, execution time speed up of the double precision DAXPY benchmark complied using the GCC optimization setting -O3 compared to the execution time of the benchmark using the GCC -O0 setting is:

1

7

14

28
