Question
1. A program has 5 billion instructions is running with a CPI of 2 on a machine with a 2.5GHZ frequency, what is the execution time in seconds?
2. In a program 40% of the instructions have a CPI of 1, 25% have a CPI of 2, 20% have a CPI of 3 and 15% have a CPI of 5. Find the number of instructions per second if the machine is running at 900 MHz?
3. If 5 processors can run a program 2 times faster than a single processor, how much faster than a single processor can 10 processors run the same program?
4. If the base machine can run the 5 SPEC benchmarks in 1Os, 20s, 30s, 40s and 60s, whereas the target machine can run them in 5s, 1Os, 5s, 10s and 40s, respectively, what is the SPEC value for this scenario?
