Dynamic Voltage and Frequency Scaling (DVFS) is a widely used methodology to reduce the power consumption of mobile devices. This scheme performs frequency scaling in accordance with a specific governor and sets an operating voltage to be paired with the frequency. Temperature is one of the critical parameters affecting device ...

Highly-parallel, high-performance scientific applications must maximize performance inside of a power envelope while maintaining scalability. Emergent parallel and distributed systems offer a growing number of operating modes that provide unprecedented control of processor speed, memory latency, and memory bandwidth. Optimizing these systems for performance and power requires an understanding of ...

Database management systems (DBMS) are typically tuned for high performance and scalability. Nevertheless, carbon footprint and energy efficiency are also becoming increasing concerns. Unfortunately, existing studies mainly present theoretical contributions but fall short on proposing practical techniques. These could be used by administrators or query optimizers to increase the energy ...

Traditional DVFS schemes are oblivious to fine-grained adaptability resulting from path-grained timing imbalance. With the awareness of such fine-grained adaptability, better power-performance efficiency can be obtained. We propose a new approach, MicroFix, to exploit such fine-grained adaptability. We first reveal the potential of the path-grained timing imbalance and then present ...

This paper presents CRISP, the first runtime analytical model of performance in the face of changing frequency in a GPGPU. It shows that prior models not targeted at a GPGPU fail to account for important characteristics of GPGPU execution, including the high degree of overlap between memory access and computation ...

Multiprocessors have become the main architecture trend in modern systems due to the superior performance; nevertheless, the power consumption remains a critical challenge. Global power management (GPM) aims at dynamically finding the power state combination that satisfies the power budget constraint while maximizing the overall performance (or vice versa). Due ...

Datacenter servers are often under-provisioned for peak power consumption due to the substantial cost of providing power. When there is insufficient power for the workload, servers can lower voltage and frequency levels to reduce consumption, but at the cost of performance. Current processors provide power limiting mechanisms, but they generally ...

Power and energy are first-order design constraints in high performance computing. Current research using dynamic voltage scaling (DVS) relies on trading increased execution time for energy savings, which is unacceptable for most high performance computing applications. We present Adagio , a novel runtime system that makes DVS practical for complex, ...

Many mobile applications utilize hardware accelerators for computation-intensive tasks. Often these tasks involve real-time user interactions and must finish within a certain amount of time for smooth user experience. In this paper, we propose a DVFS framework for hardware accelerators involving real-time user interactions. The framework automatically generates a predictor ...

This paper investigates a novel energy-proportional concept that combines closed-loop voltage scalability and run-time hardware reconfiguration. Voltage scaling is based on in-situ detectors that allow the device to detect valid working voltage and frequency pairs at run-time. The combined approach named AVLS (Adaptive Voltage and Logic Scaling) enables the adaptation ...
