Suppose we have two different compilers, A and B, which each compile the same Java program to a particular computer’s machine language. Compiler A results in a program with 2.0 x 109 instructions and a CPU time of 1.1s. Compiler B results in a program with 2.4 x 109 instructions and a CPU time of 1.5s. What is the average CPI for each compiler’s program if the computer’s processor has a clock cycle time of 1ns? Suppose a new compiler C is developed which results in a program with 9.2 x 108 instructions and a CPI of 1.1. What is the speedup of using compiler C instead of compiler A? Instead of compiler B? Suppose we run the programs compiled by compilers A and B on two separate computers. Suppose also that the CPU time for each is exactly the same. How much faster is the clock running compiler A’s code versus the clock running compiler B’s code? (Hint: the first step is to calculate the total cycles each program requires)

Question

Suppose we have two different compilers, A and B, which each compile the same Java program to a particular computer’s machine language.

  • Compiler A results in a program with 2.0 x 109 instructions and a CPU time of 1.1s.
  • Compiler B results in a program with 2.4 x 109 instructions and a CPU time of 1.5s.
  1. What is the average CPI for each compiler’s program if the computer’s processor has a clock cycle time of 1ns?
  2. Suppose a new compiler C is developed which results in a program with 9.2 x 108 instructions and a CPI of 1.1. What is the speedup of using compiler C instead of compiler A? Instead of compiler B?
  3. Suppose we run the programs compiled by compilers A and B on two separate computers. Suppose also that the CPU time for each is exactly the same. How much faster is the clock running compiler A’s code versus the clock running compiler B’s code? (Hint: the first step is to calculate the total cycles each program requires)
