Suppose a program takes $25$ seconds to run on a particular hard ware. Now suppose on a new

hardware, $[x]\%$ of instructions can be run parallel by a factor of $9$ times. Calculate the

overall speed up that has been achieved. Also what is the new execution time.

Note: For value of $x,$ use last two digits of your student number.

A quad core processor could speed up a computer by a factor of $4$ but this rarely happens. Use

Amdahl's Law to compute the percentage of program execution that needs to be distributed

across all $4$ cores to achieve an overall speedup of

a$)3.$

b$)1\mathrm{.}25$
