Abstract

Most previous researches on thermal management of many-core architectures focus on the control of either core resources or network resources only, even though both have significant thermal impacts. This paper proposes a holistic thermal management that applies dynamic voltage/frequency scaling to cores and routers together to maximize system performance under temperature constraint. The proposed method first determines a power budget given in aggregate weighted power for every pillar of vertically adjacent tiles. Then it performs voltage/frequency assignment under the budget while exploiting the characteristics of the applications. Experiments show that our approach outperforms existing methods.
