Abstract

This paper presents a statistical approach of finding a set of optimum compiler options to minimize the energy consumption of the compiled executable. The method employs a statistical, non-parametric analysis, namely the Mann-Whitney test, to determine a set of options to be turned on and off for a particular source code. Energy measurements show that an improvement of up to 15% over the default optimization set up of the compiler can be achieved with this methodology.
