Hardware-Based Energy Accounting for Multi-Core Systems

Verteidigung der Diplomarbeit, Sondertermin: 15:00 Uhr, APB 2101

In this talk I present I novel approach, which allows accurate low-overhead energy measurements of individual programs or arbitrary groups of them on commercial off-the-shelf multi-core hardware. The measurements are based on the Running Average Power Limit processor feature available in recent Intel processors and utilize a special scheduling algorithm to make accurate energy accounting possible.
Within the talk I will outline the different obstacles which had to be overcome to be able to implement this technique in the Linux kernel as well as present energy measurement results of various different benchmarks which show that the implemented approach actually can deliver a high measurement accuracy while maintaining a low runtime overhead.
