    Question 1: [5 Marks]

    Use the Amdahl’s Law (mentioned below) to prove that the speed up does not remain the same, as the ratio of
    sequential code and number of processors (on which this code is executed) is doubled.
    Initial fraction of code that can be executed sequentially = 10%
    Initial number of processors = 100
    Note: Assumes zero (0) overhead and “perfect” parallelism.
    You have to compare both the results (initial result and result after doubling the given values)

    Question 2: [5 Marks]

    Suppose, we are performing 20 tasks sequentially using a machine each task taking 5 seconds. Now we are
    planning to divide each task into 5 sub-tasks and perform these tasks using pipelining.
    How much speed up, we will get after applying the pipelining concept.
    Note: You have to perform and show the mathematical calculations in the solution.
    Note: Deadline for Assignment submission is 18th January, 2017.
