  1. 21. Static instruction scheduling for high performance on energy-efficient processors

    Författare :Kim-Anh Tran; Alexandra Jimborean; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : New trends such as the internet-of-things and smart homes push the demands for energy-efficiency. Choosing energy-efficient hardware, however, often comes as a trade-off to high-performance. LÄS MER

  3. 22. Exhaustion Dominated Performance: Methodology, Tools and Empirical Experiments

    Författare :Nima Namaki; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; engineering simulation applications.; measurement methodology; Computer cluster; verification methods; resource exhaustion;

    Sammanfattning : Problem with application sensitivity to insufficient resources in High PerformanceComputing (HPC) clusters has been a longstanding issue of concern for industries. Inthis thesis we propose a method based on a black box approach for characterizationand analysis of engineering simulation applications with respect to available hardwareresources in the situation of resource depletion.

    Sammanfattning : Over the past decade, the field of personal electronic systems has trended toward mobile and wearable devices. However, the capabilities of existing electronic systems are overwhelmed by the computing demands at the wearable sensing stage. Two main bottlenecks are encountered. LÄS MER

  7. 25. Achieving Low Latency and High Throughput over Cellular Internet Connections

    Författare :Habtegebreil Kassaye Haile; Anna Brunström; Karl-Johan Grinnemo; Per Hurtig; Simone Ferlin; Markku Kojo; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QUIC; BBR; Copa; TCP; Congestion control; Throughput; Queuing Delay; Performance Evaluation; 4G; 5G; Kalman Filter; Computer Science; Datavetenskap;

    Sammanfattning : The continuous increase in the number and type of Internet services and their requirements for improved QoS has motivated the steady evolution  of cellular networks towards the current fifth generation (5G) systems. However, updating the network to 5G is insufficient to satisfy application requirements since performance limitations can also exist in the transport used by the applications. LÄS MER
