A thermal-aware scheduling for multicore architectures

With the advance of technology, the power density (temperature) increases rapidly to threaten system performance, reliability, and even system safety. Development of a thermal management method to reduce thermal hotspots and distribute the temperature uniformly has become an important issue. Therefore, dynamic thermal management (DTM) has emerged as an effective technique to remedy these issues above. In this paper, we propose a proactive thermal management scheme on the Criticore platform developed by our team to avoid suffering high temperature of the system. The proposed approach can schedule threads to prevent the system from overheating with the aid of the thermal sensors and the Power Management Circuit (PMC) designed in the Criticore. Furthermore, a novel thread migration is also presented to increase the reliability of the system.
