Processor power consumption produces significant heat and can result in higher average operating temperatures. High operating temperatures can lead to reduced reliability and at times thermal emergencies. Previous thermal-aware techniques use Dynamic Voltage and Frequency Scaling (DVFS) or multithreaded or multicore process migration to reduce thermals. However, these methods do not gracefully handle scenarios where processors are fully loaded, i.e. there are no free threads or cores for process scheduling. The authors propose techniques to reduce processor temperature when processors are fully loaded.
