Keynote speech: IGSC 2017: Green computing through adaptive multi-core architectures

Abstract

Current homogeneous and heterogeneous multi-cores consist of processors with static architectures and fixed sets of hardware resources. In contrast, the computational demands of many applications vary not only from one task to the other, but also temporally, during the execution of a single task. Such high level of diversity results in a mismatch between the requirements of the application and the hardware resources provided by the multi-core, causing an energy inefficient execution. We will discuss in this presentation adaptive multi-core architectures that are capable of adjusting their hardware resources in real time to match the current computational needs of the executing application.
