NVIDIA GPGPUs Instructions Energy Consumption
2020 IEEE International Symposium on Performance Analysis of Systems and Software (ISPASS)(2020)
摘要
In this work, we accurately measure the energy consumption of the different instructions that can be executed in modern NVIDIA GPGPUs. We use three different software techniques to read the GPU on-chip power sensors, which use NVIDIA’s NVML API and provide an in-depth comparison between these techniques. Additionally, we verified the software measurement techniques against a custom-designed hardware power measurement. The results show that Volta GPUs have the best energy efficiency of all the other generations for the different categories of the instructions. This work should give GPU architects and developers a more concrete understanding of these representative NVIDIA GPUs’ microarchitecture. It should also make energy measurements of any GPU kernel both efficient and accurate.
