Runtime power-aware energy-saving scheme for parallel applications

Runtime Power-Aware Energy-Saving Scheme for Parallel Applications

Energy consumption has become a major design constraint in modern computing systems. With the advent of peta ops architectures, power efficient software stacks have become imperative for scalability. Modern processors provide techniques, such as dynamic voltage and frequency scaling (DVFS), to improve energy efficiency on-the-fly. Without careful application, however, DVFS and throttling may ca...

A Traffic Aware Energy Saving Scheme for Multicarrier HSPA+

In the near future, an increase in cellular network density is expected to be one of the main enablers for the newly introduced challenging capacity goals. This development will lead to an increase in the network energy consumption. In this context, we propose an energy efficient dynamic scheme for HSDPA+ (High Speed Downlink Packet Access-Advanced) systems aggregating several carriers. In the ...

A Power-Saving Algorithm and a Power-Aware Routing Scheme for IEEE 802.11 Ad Hoc Networks

Power aware reconfigurations of parallel applications

Current architectures provide many possibilities for the reduction of power consumption of applications, such as reducing the number of used cores or scaling down their frequency. However, the amount of resources allocated to an application is usually static and fixed by the programmer or by the runtime. While there are cases where such a static choice may be appropriate, other scenarios may re...

Energy aware list-based scheduling for parallel applications in cloud

As the growth of energy consumption has been explosive in current data centres and cloud systems, it has drawn greater attention in academia, industry and government. Task scheduling as a core in systems, it has become an important method to reduce energy dissipation. This paper proposes an energy aware list-based scheduling algorithm called EALS for parallel applications in the context of serv...
