Let $f$ be the fraction of the computation (in terms of time) that is parallelizabl$e$. $P$ the number of processors in the system, and $s_p$ the speed up achievable in comparison with sequential execution – then the $s_p$ can be calculated using the relation: $\frac{1}{1-f-f/P}$ $\frac{P}{P-f(P+1)}$ $\frac{1}{1-f+f/P}$ $\frac{P}{P+f(P-1)}$
