| 摘要: |
| 随着规模和计算密度的不断提升,大规模计算系统面临严峻的功耗危机,控制最大功耗是系统功耗管理的一个重要目标.针对大规模计算系统,引入超标功耗持续率ΔP×T 作为功耗控制的评价标准,提出面向机群系统的最大功耗控制模型NInO,并基于NInO 模型设计了两个功耗控制示范算法NInO-P 和NInO-ΔP.最后,对所提出的基于NInO 模型的各项技术进行综合测评与验证. |

| Abstract: |
| Power consumption is a huge challenge for large scale systems, and power capping is an important goal of power management. Power overspending accumulative ratio ΔP×T is introduced as the metric to power capping. For large scale systems, NInO model is proposed to control the power consumption of clusters. Two example algorithms, NInO-P and NInO-ΔP, are designed based on NInO. Finally, the power capping with NInO is proved in experiments. |
