  1. 1. Techniques to Improve Energy Efficiency on Heterogeneous Multiprocessors under Timing and Quality Constraints

    Author : Muhammad Waqar Azhar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thread throttling; Energy Efficiency; Dynamic Voltage Frequency Scaling DVFS ; Quality of Service; Heterogeneous multiprocessor; Soft real time systems.; Resource management; Core migration;

    Abstract : Traditionally, applications are executed without the notion of a computational deadline and often use all available system resources, which leads to higher energy consumption. User specification of Quality of Service (QoS) constraints, in terms of completion time and solution quality, opens up for allocation of just enough resources to an application to finish just in time and thereby save energy.

  2. 2. Energy Efficient Task Mapping and Resource Management on Multi-core Architectures

    Author : Jing Chen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Consumption; Resource Management; Runtime; Dynamic Voltage-Frequency Scaling DVFS ; Predictive Models; Task Scheduling;

    Abstract : Reducing energy consumption of parallel applications executing on chip multi- processors (CMPs) is important for green computing. Hardware vendors have been developing a variety of system features to support energy efficient computing, for example, integrating asymmetric core types on a single chip referred to as static asymmetry and supporting dynamic voltage and frequency scaling (DVFS) referred to as dynamic asymmetry.

  3. 3. QoS Driven Coordinated Management of Resources to Save Energy in Multi-Core Systems

    Author : Mehrzad Nejat; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Re-configurable Core Architecture; Dynamic Voltage-Frequency Scaling DVFS ; Energy Efficiency; Quality-of-Service QoS ; Resource Management; Cache Partitioning;

    Abstract : 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. READ MORE

  4. 4. Adaptive Task Scheduling and Resource Management Techniques for Improving Energy Efficiency on Multi-core Systems

    Author : Jing Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic Voltage and Frequency Scaling DVFS ; Performance Modeling; Energy Efficiency; Runtime System; Power Modeling; Task Scheduling;

    Abstract : The growing impact of energy on operational cost and system robustness becomes a strong motivation for improving energy efficiency in parallel computing systems, in addition to performance. Hardware features such as core asymmetry and Dynamic Voltage and Frequency Scaling (DVFS) aim to provide opportunities for energy-efficient computing. READ MORE

    Abstract : Transactional Memory (TM) is an emerging programming paradigm that drastically simplifies the development of concurrent applications by relieving programmers from a major source of complexity: how to ensure correct, yet efficient, synchronization of concurrent accesses to shared memory. Despite the large body of research devoted to this area, existing TM systems still suffer from severe limitations that hamper both their performance and energy efficiency. READ MORE
