According to Benjamin Franklin, life holds but two certainties, death and taxes. As we enter the mobile era, the primary mobile device, i.e., the smartphone, faces the certainties of adopting agressive sleeping polices to conserve battery energy, ...

Mobile operating systems embrace new mechanisms that reduce energy consumption for common usage scenarios. The background app design is a representative implemented in all major mobile OSes. The OS keeps apps that are not currently interacting with the ...

Recently, there has been a surge of interests on developing techniques and architectures for prefetching ads to potentially reduce the smartphone energy drain by 3G/4G radios from fetching ads. Despite the development of prefetching techniques, it ...

In order to minimize the container server power consumption, a new cooling system that incorporates fan-less servers and fresh-air cooling is proposed.

In a conventional container data center, the required air flow for sever cooling is supplied by both ...

We consider the use of fuel cells for powering data centers, based on benefits in reliability, capital and operational costs, and reduced environmental emissions. Using fuel cells effectively in data centers introduces several challenges and we ...

Customers are levied a charge by the cloud service providers for using their services and the attractiveness of the offered pricing plan is one of the key determinants in the cloud adoption. The paper presents a synergistic cloud where the pricing plan, ...

Main Memory is responsible for a large and increasing fraction of the energy consumed by multi-core systems. Therefore, it is critical to address the power issue in the memory subsystem. In this paper, we present a solution to improve memory power ...

More than 90% of consumer computers use integrated graphics processors. In these processors, the CPU and the GPU share the same physical memory. Due to high density, good power efficiency, and low cost, integrated graphics processors are promising ...

In recent years we have seen the emergence of context-aware mobile sensing apps which employ machine learning algorithms on real-time sensor data to infer user behaviors and contexts. These apps are typically optimized for power and performance on the ...

Nowadays, GPUs are widely used to accelerate many high performance computing applications. Energy conservation of such computing systems has become an important research topic. Dynamic voltage/frequency scaling (DVFS) is proved to be an appealing method ...

Although multicore smartphones have become increasingly mainstream, it is unclear whether and how smartphone applications can utilize multicore CPUs to improve performance. In this paper we study the performance of mobile applications using multicore ...

Energy management is a primary consideration in the design of modern smartphones, made more interesting by the recent proliferation of multi-core processors in this space. We investigate how core offlining and DVFS can be used together on these systems ...

We examine the problem of assigning computing resources to an application to meet a performance goal while minimizing energy consumption. We present a general formulation of this problem as a linear program, discuss several potential heuristic solutions,...
