James Pallister presents research into the effect of compiler options on energy consumption at OSHUG #22

Energy efficiency is the highest priority for modern software-hardware co-design. The potential for compiler options to impact on power consumption of running programs has often been discussed. However there has never been a comprehensive analysis of the magnitude of that impact, or how it varies between processor architectures and compilers.

This presentation describes a project undertook during the the Summer of 2012 at the University of Bristol Department of Computer Science and funded by Embecosm, to explore the effect of compiler options on energy consumption of compiled programs.
