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 – 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)) |
