It does not take into account the capabilities of the instructions. 2. MIPS can vary inversely with performance. 3. MIPS varies between programs on the same computer.

Which of the following are the problems with using Millions instructions per second (MIPS) as a measure for comparing computer performance? 1. It does not take into account the capabilities of the instructions. 2. MIPS can vary inversely with performance. 3. MIPS varies between programs on the same computer. Correct Answer 1 and 3 only

EXPLAINATION-

MIPS-

  • It Stands for "Million Instructions Per Second."
  • It is a method of measuring the raw speed of a computer's processor.
  • Since the MIPS measurement doesn't take into account other factors such as the computer's I/O speed or processor architecture or capability of instruction, it isn't always a fair way to measure the performance of a computer. So statement 1 is correct.
  • The different architecture of CPU(RISC and CISC) uses different MIPS for the execution of a program.
  • So MIPS has no relation with performance. So statement 2 is incorrect.
  • CPU inserts variable delay cycle as per priorities hence MIPS varies between programs on the same computer. So statement 3 is correct.

Time taken by a bus varies as the distance and inversely as the velocity. On the other side velocity varies directly as cube of petrol used for the journey per kilometer and inversely as the number of boxes the bus is carrying in the journey. Bus complete the journey of 100 km in 2 hours and carry 10 boxes for which petrol required is 10 litters. Find how much of petrol will be used for the journey of 50 km in 5 hours with 4 boxes.
Assume that we test the performance of two processors, P1 and P2, on a program. We find the following about each: Processor P1 has a CPI of 2 and executes 2 billion instructions per second. Processor P2 has a CPI of 1 and executes 8 billion instructions per second. Which processor has higher performance on this program? (Recall that CPI stands for Cycles Per Instruction.)
