  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 :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; 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. Efficient Memory Access and Synchronization in NoC-based Many-core Processors

    Författare :Xiaowen Chen; Zhonghai Lu; Umit Ogras; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Many-core; Network-on-Chip; Distributed Shared Memory; Microcode; Virtual-to-physical Address Translation; Memory Access Fairness; Barrier Synchronization; Cooperative Communication; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In NoC-based many-core processors, memory subsystem and synchronization mechanism are always the two important design aspects, since mining parallelism and pursuing higher performance require not only optimized memory management but also efficient synchronization mechanism. Therefore, we are motivated to research on efficient memory access and synchronization in three topics, namely, efficient on-chip memory organization, fair shared memory access, and efficient many-core synchronization.

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

    Författare :Afshin Zafari; Elisabeth Larsson; George Bosilca; Uppsala universitet; []
    Nyckelord :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

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

    Författare :Anders Gidenstam; Chalmers tekniska högskola; []
    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
