HybDTM: a coordinated hardware-software approach for dynamic thermal management
With ever-increasing power density and cooling costs in modern high-performance systems, dynamic thermal management (DTM) has emerged as an effective technique for guaranteeing thermal safety at run-time. While past works on DTM have focused on different techniques in isolation, they fail to consider a synergistic mechanism using both hardware and software support and hence lead to a significant execution time overhead. In this paper, we propose HybDTM, a methodology for fine-grained, coordinated thermal management using a hybrid of hardware techniques, such as clock gating, and software techniques, such as thermal-aware process scheduling, synergistically leveraging the advantages of both approaches. We show that while hardware techniques can be used reactively to manage thermal emergencies, proactive use of lowoverhead software techniques can rely on application-specific thermal profiles to lower system temperature. Our technique involves a novel regression-based thermal model which...
