Sammanfattning : Reducing the energy consumption of computing systems is a necessary endeavor. However, saving energy should not come at the expense of degrading user experience. To this end, in this thesis, we assume that applications running on multi-core processors are associated with a quality-of-service (QoS) target in terms of performance constraints. LÄS MER
Sammanfattning : Energy consumption has become one of the main design constraints in today’s integrated circuits. Techniques for energy optimization, from circuit-level up to system-level, have been intensively researched. LÄS MER
Sammanfattning : The aim of this thesis is to analyse the power-performance tradeoffs in datacenter servers, create models that capture these tradeoffs, and propose controllers to optimise the use of data center infrastructures taking the tradeoffs into consideration. The main research problem that we investigate in this thesis is how to increase the power efficiency of data center servers taking into account the power-performance tradeoffs. LÄS MER
Sammanfattning : The overall goal of the work presented in this thesis was to find ways of managing power-performance tradeoffs in cloud data centers. To this end, the relationships between the power consumption of data center servers and the performance of applications hosted in data centers are analyzed, models that capture these relationships are developed, and controllers to optimize the use of data center infrastructures are proposed.

Sammanfattning : It is well recognized in the literature that the fully-synchronous design style, once the best choice due especially to the simplicity of its design flow, is not suitable for present-days systems, which contain many more gates compared to their predecessors, and has to be superseded to meet the new needs of the industry. The alternative solution that has enjoyed more success in industry and the literature consists in breaking down a system into several fully-synchronous modules clocked with independent clocks. LÄS MER
