Energy consumption has become a core concern in computing systems. In this context, power capping is an approach that aims at ensuring that the power consumption of a system does not overcome a predefined threshold. Although various power capping techniques exist in the literature, they do not fit well the nature of multi-threaded workloads with shared data accesses and non-minimal thread-level concurrency.

ulti-threaded applications facilitate the exploitation of the computing power of multicore architectures. On the other hand, these applications can become extremely energy-intensive, in contrast with the need for limiting the energy usage of computing systems.
