This paper examines the effect of compiler optimizations on the energy usage and power consumption of the Intel Pentium 4 processor. We measure the effects of different levels of general optimization and specific optimization. We classify general optimizations as those compiler flags which enable a set of compiler optimizations. Specific optimizations are those which can be enabled and disabled individually. The three specific optimizations we study are loop unrolling, loop vectorization, and… CONTINUE READING
