Power Modeling for Heterogeneous Processors

Abstract: As power becomes an ever more important design consideration, there is a need for accurate power models at all stages of the design process. While power models are available for CPUs and GPUs, only simple models are available for heterogeneous processors. We present a micro-benchmarkbased modeling technique that can be used for chip multiprocessor (CMPs) and accelerated processing units (APUs). We use our approach to model power on an Intel Xeon CPU and an AMD Fusion heterogeneous processor. The resulting erro… Show more

“…Our PE model has a maximum percentage error smaller than 2% across all four metrics, while that of the comparable state of the art is in the range of 2%-7% on a single metric [16,17,18,19,20,21]. Moreover, the efficient setup for data extraction and the heuristic search of models help us to reach higher accuracy with less time spent for acquiring data and training the model.…”

“…State-of-the-art estimation models can be distinguished as MLbased [16,17,18] and formal [19,20,21] ones. ML-based models tend to use accurate sensors and interfaces to estimate the power, and hence require external modifications.…”

“…Power modeling methodologies have been also studied [Diop et al 2014; Austin and Wright 2014] to analytically study the evolution of processor power as a function of voltage, frequency, and temperature. Skadron et al [2004] in particular studied the role of temperature on leakage, leading to a more realistic power equation.…”

“…Tahir [6] simulates the total power dissipation of the APU and uses the externally connected power measurement unit to measure the power consumption of the processor. We use the Multi2Sim simulator to simulate AMD's EverGreen APUs and obtain performance counter information, including Request to L2 Cache, L2 Cache Miss and DRAM Access, to estimate the power consumption of the processor using the regression model.…”
