  1. 1. Distributed cognition in home environments : The prospective memory and cognitive practices of older adults

    Författare :Mattias Forsblad (Kristiansson); Nils Dahlbäck; Corinna Kruse; Fredrik Stjernberg; Oskar Lindwall; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; HUMANITIES; HUMANIORA; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; HUMANIORA; SOCIAL SCIENCES; SOCIAL SCIENCES; HUMANITIES; Distributed cognition; intelligent use of space; cognitive aging;

    Sammanfattning : In this thesis I explore how older people make use of, and interact with, their physical environment in home and near-by settings to manage cognitive situations, specifically prospective memory situations. Older adults have in past research been shown to perform better on prospective memory in real-life settings than what findings in laboratory-like settings predict. LÄS MER

  3. 2. Multi-Threaded Distributed System Simulations : Using Bi-Lateral Delay Lines

    Författare :Robert Braun; Petter Krus; Asko Ellman; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : As the speed increase of single-core processors keeps declining, it is important to adapt simulation software to take advantage of multi-core technology. There is a great need for simulating large-scale systems with good performance. LÄS MER

  4. 3. Advances in Task-Based Parallel Programming for Distributed Memory Architectures

    Författare :Afshin Zafari; Elisabeth Larsson; George Bosilca; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel programming; task-based programming; distributed memory system; scientific computing; hierarchical data; hierarchical tasks;

    Sammanfattning : It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. LÄS MER

  5. 4. Algorithms for synchronization and consistency in concurrent system services

    Författare :Anders Gidenstam; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; threading; plausible clocks; memory management; event ordering; lock-free; optimistic causal order; nonblocking; group communication; synchronization; memory reclamation; time stamping system; logical clocks; atomic registers.;

    Sammanfattning : Synchronization, consistency and scalability are important issues in the design of concurrent computer system services. In this thesis we study the application of optimistic and scalable methods in concurrent system services. LÄS MER

  7. 5. Towards Low-Complexity Scalable Shared-Memory Architectures

    Författare :Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

    Sammanfattning : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. LÄS MER
