find me solutions for the following problem:

Let's explore the performance impact of transforming a program so it runs on multiple cores rather than a single processor. 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, the program in question requires the execution of $2\mathrm{.}56$E$9$ arithmetic instructions, $1\mathrm{.}28$E$9$ load$/$store instructions, and $256$ million branch instructions. Assume that each of the processor cores has a clock frequency of $2$ GHz$.$ Assume that, as the program is parallelized to run with multiple cores, the number of arithmetic and load$/$store instructions per processor is divided by $0\mathrm{.}7$ x p $($where p is the number of cores$)$ but the number of branch instructions per processor remains the same.
