System-Level Dynamic Thermal Management for High-Performance Microprocessors
Abstract--Thermal issues are fast becoming major design constraints in high-performance systems. Temperature variations adversely affect system reliability and prompt worst-case design. In recent history, researchers have proposed dynamic thermalmanagement (DTM) techniques targeting average-case design and tackling the temperature issue at runtime. While past work on DTM has focused on different techniques in isolation, it fails to consider a system-level approach which uses both hardware and software support in a synergistic fashion and hence leads to a significant execution-time overhead. In this paper, we propose HybDTM, a system-level framework for doing fine-grained coordinated thermal management using a hybrid of hardware techniques (like clock gating) and software techniques (like thermal-aware process scheduling), leveraging the advantages of both approaches in a synergistic fashion. We show that while hardware techniques can be used reactively to manage the overall temperature...
