$8.(5)$ ProgramC consists of a serial $($i$.$e$.,$ sequential$)$ part that must be executed on a

single processor before the remaining parallel part comprised of $8$ independent indivisible

tasks. Each of the $8$ independent tasks takes $61\mathrm{.}5$ ms to execute on a single core. The

serial part takes $328$ ms$.$

The sub module $12$B: mod$12\_1\mathrm{.}2$ Parallel Performance explains Amdahl$$s law as it

relates to multi$-$processor systems. Module $12$ also defines strong scaling and weak

scaling. Assume ProgramC is first executed on a single$-$core system. Strong scaling is

then used to execute the ProgramC again using one core for the serial part followed by

using $8$ cores for the parallel $($one core per task$).$ What speedup ratio does Amdahl$$s law

predict for ProgramC using the $8$ cores compared to using a single core? Show how you
