$1\mathrm{.}10$ Assume for arithmetic, load$/$store$,$ and branch instructions, a processor has CPIs of $1,12,$ and $5,$ respectively. Also assume that on a

single processor a program requires the execution of $2\mathrm{.}56E9$ arithmetic instructions, $1\mathrm{.}28$E$9$ load$/$store instructions, and $256$ million branch instricictions. Assume that each processor has a $2GHz$ clock frequency. Assume that, as the program is parallelized to run over multiple cores, the number of arithmetic and load$/$store instructions per processor is divided by $0\mathrm{.}7p($where $p$ is the number of processors$)$ but the number of branch instructions per processor remains the same. $1\mathrm{.}10\mathrm{.}1[5]$$$1\mathrm{.}7>$ Find the total execution time for this program on $1,2,4,$ and $8$ processors, and show the relative speedup of the $2,4,$ and $8$ processor result relative to the single processor result.
