Abstract

A modern Petascale System consists of millions of different components, which consume a huge amount of energy. The power rating of each component depends on the type of the current instructions, executed on cores, memory controllers, network units and other various components. There are a lot of influences and complicated dependencies between the software, environment and the energy consumption. The objective of this work is to identify and understand the energy consumption of processors and memory in the consideration of kernel operations. Another important goal is to develop the methodology by which the developers and users could estimate the energy consumption of the different algorithms on different systems with minimal effort and satisfying accuracy.
