Hierarchical Dynamic Thermal Management Method for High-Performance Many-Core Microprocessors

Dynamic Thermal Management for High-Performance Microprocessors

With the increasing clock rate and transistor count of today’s microprocessors, power dissipation is becoming a critical component of system design complexity. Thermal and power-delivery issues are becoming especially critical for high-performance computing systems. In this work, we investigate dynamic thermal management as a technique to control CPU power dissipation. With the increasing usage...

Thermal Field Management for Many-core Processors

This paper first presents an analysis of the global thermal field in many core processors in deep nanometer (to 16nm) nodes under power and thermal budget. We show that the thermal field can have significant spatiotemporal non-uniformity along with high maximum temperature. We propose spatiotemporal power multiplexing as a proactive method to reduce spatial and temporal temperature gradients. S...

Coordinated Power, Energy, and Temperature Management for High-Performance Microprocessors

High-performance desktop and server processor design is hampered by constraints on chip power, temperature, and energy. We have investigated dynamic power characteristics of high-performance pipelines and static energy management techniques for large on-chip caches in previous work. Our analysis indicates that a large portion of the power budget is devoted to overhead, spending power to achieve...
