Multi-core processors have become the de facto standard of computing systems in all market segments: smartphones, laptops, desktops, and servers. A fundamental problem is being able to control the operation of the individual cores so as to maximize some suitably chosen measure of quality of service. Often, the primary goal in the design of any computing...

The transition to multi-core processors has allowed their continued improvement within their limited power budget by using threads on multiple cores. By reducing the power per core and increasing the number of cores initially allowed, it is possible to circumvent the power wall of single core processors. Unfortunately, multi-core scaling is fast becoming...
