Suppose the computer contains a special processor processing a floating$-$ operation as a part of a program that calculates the GPA of the student. Consider the following cases: a$)$ Speedup the overall parallel processing $10$ times faster on $10\%$ computational time $($fraction time$)$ for the floating$-$ operations. $(2$ s$)$ b$)$ Modify the compiler to use $80\%$ of the computational time for the floating$-$ operations with the same enhancement of speedup $(10$ times$).$ Compute the overall speedup enhancem UF$16$ ent of the parallel processing. $(1)$ c$)$ Assume that the number of processors can be unlimited on $10\%$ computational time $($fraction time$)$ for the floating$-$ operations. Computer the overall speed enhancement for this case. $(1)$ d$)$ Explain the overall speedup enhancement for the result of section $($a$),($b$)$ and $($c$).$
