Power and energy consumption analysis on intel SCC many-core system
Pollawat Thanarungroj, Chen Liu · 2011
As semiconductor manufacturing technology continues to scale down, it is possible to integrate more transistors into a processor, which gives birth to many-core processor design. This paper introduces an approach to analyze the power and energy consumption of a many-core research platform. The investigation has been done by using the Intel SCC system as an experimental platform. The approach is to collect the time and power profiling of an executing parallel application on the Intel SCC system. And then, the total energy consumed by the entire execution is calculated as a consequence. We studied the effects of power and energy consumption in many-core systems by varying different hardware configuration parameters such as number of cores, clock frequency and voltage level. Thus, the many-core system can be explored for its scalability and fitness in operational cost and performance.
