Abstract

The percentage of inactive nodes or dark nodes (we refer to dark nodes as dumso) in many-core systems increases because of power dissipation caused by continuous scaling in technology. To address this challenge, existing work employ several techniques. Some techniques place the dumso nodes strategically between active nodes to alleviate the temperature by choosing the nodes which are far away from each other. However, this increases the latency between nodes which require inter communication leading to performance degradation. Others employ Dynamic Thermal Management (DTM) to vary the Voltage Frequency (V/F) Scaling of the nodes whilst Task migration is used to migrate tasks. In this paper, an Ageing Before Temperature Eletromigration-Aware Neighbour Allocation (ABENA) is proposed to alleviate the temperature of the nodes by using the Lifetime of nodes as the main parameter. Experiments show that our approach improves the lifetime of nodes.
