  1. 1. Improving Energy-Efficiency of Multicores using First-Order Modeling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Vasileios Spiliopoulos; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; DVFS; Cache Resizing; Interval modeling; Power modeling; Computer Science; Datavetenskap;

    Abstract : In the recent decades, power consumption has evolved to one of the most critical resources in a computer system. In the form of electricity bill in data centers, battery life in mobile devices, or thermal constraints in desktops and laptops, power consumption imposes several limitations in today’s processors and improving power and energy efficiency is one of the most urgent research topics of Computer Architecture.

  2. 2. Efficient Execution Paradigms for Parallel Heterogeneous Architectures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Konstantinos Koukos; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupled Execution; Performance; Energy; DVFS; Compiler Optimizations; Heterogeneous Coherence; Computer Science; Datavetenskap;

    Abstract : This thesis proposes novel, efficient execution-paradigms for parallel heterogeneous architectures. The end of Dennard scaling is threatening the effectiveness of DVFS in future nodes; therefore, new execution paradigms are required to exploit the non-linear relationship between performance and energy efficiency of memory-bound application-regions.

  3. 3. Techniques to Save Energy in Heterogeneous Multicore Architectures under QoS Constraints

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Muhammad Waqar Azhar; [2019]

    Abstract : Typically, applications are run with available system resources leading to over-provisioning of resources which can lead to high energy consumption. If the computational demand is specified, in terms of a Quality of Service (QoS) contract, it is possible to devote just enough resources to applications and thereby reduce energy consumption.

  4. 4. Efficient Processing and Storage for Massive MIMO Digital Baseband

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Yangxurui Liu; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital signal processor; baseband processing; parallel memories; data compression; channel sparsity; Reconfigurable computing; QR decomposition; resource scheduling; massive MIMO; MIMO; DVFS;

    Abstract : Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its actual deployment.

    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
