Fitness: A Metric Describing the Efficiency of Microarchitectual Utilization

Simon Holmbacka, Johan Lilius, Fitness: A Metric Describing the Efficiency of Microarchitectual Utilization. In: Sven Karlsson, Karin Tunder (Eds.), Seventh Swedish Workshop on Multicore Computing, 1–4, Techical University of Denmark, 2015.

Abstract:

We identify a new metric called Fitness, which describes the microarchitectual utilization of a CPU. The metric is used when exploring mapping decisions on heterogeneous architectures, i.e. when determining which architecture is best suited for the job. As certain software algorithms execute
more efficiently (in terms of energy) on a given set of architectures but not on others, the Fitness value determines which architecture to choose for what software execution. Evaluations on a heterogeneous big.LITTLE Exynos 5410 CPU shows promising results of its accuracy.
