The multi-processor architectures are becoming popular in both desktop and mobile processors. Among multiprocessor architectures, asymmetric architectures show promise in saving energy and power. However, the performance and energy consumption behavior of asymmetric multiprocessors with desktop-oriented multithreaded applications has not been studied widely. In this paper, the authors measure performance and power consumption in asymmetric and symmetric multiprocessors using real 8 and 16 processor systems to understand the relationships between thread interactions and performance/power behavior.
