A Survey of Power Consumption Modeling for GPU Architecture

GPUs are of increasing interests in the multi-core era due to their high computing power. However, the power consumption caused by the rising performance of GPUs has been a general concern. As a consequence, it is becoming an imperative demand to optimize the GPU power consumption, among which the power consumption estimation is one of the important and useful solutions. In this work, we give a survey of the power modeling for GPU. We first introduce the current development of heterogeneous architectures and then summarize the existing modeling techniques for GPU power consumption. The main two types of power modeling could be classified as simulator-based methods and real machine-based methods.
