Que. Let f be the fraction of a computation (in terms of time) that is parallelizable, P the number of processors in the system, and sp the speed up achievable in comparison with sequential execution ā€“ then the sp can be calculated using the relation :
a. 1 /(1 - f - (f/P))
b. P/ P - f(P + 1)
c. 1/ (1 - f + (f/P))
d. P /(P + f(P - 1))
Answer:1/ (1 - f + (f/P))
