The sustained push for performance, transistor count, and instruction level parallelism has reached a point where chip level power density issues are at the forefront of design constraints. Many high performance computing platforms are integrating several homogeneous or heterogeneous processing cores on the same die to fit small form factors. Due to the design limitations of using expensive cooling solutions, such complex chip multiprocessors require an architectural solution to mitigate thermal problems. Many of the current systems deploy Dynamic Voltage and Frequency Scaling (DVFS) to address thermal emergencies, either within the operating system or hardware.
