  1. 16. Shared Memory Objects as Synchronization Abstractions: Algorithmic Implementations and Concurrent Applications

    Författare :Ioannis Nikolakopoulos; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concurrent data structures; parallelism; lock-free synchronization; data stream processing; iteration;

    Sammanfattning : Multicore and many-core architectures have penetrated the vast majority of computing systems, from high-end servers to low-energy embedded devices. From the hardware's perspective, performance scalability comes in the form of increasing numbers of cores. Nevertheless, fully utilizing this power is still an open research and engineering issue.

  3. 17. Capability-Based Type Systems for Concurrency Control

    Författare :Elias Castegren; Tobias Wrigstad; Dave Clarke; Alan Mycroft; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Programming languages; Type Systems; Capabilities; Concurrency; Parallelism; Data-Race Freedom; Lock-Free Data Structures; Object-Oriented Programming; Actors; Active Objects; Object Calculi; Semantics;

    Sammanfattning : Since the early 2000s, in order to keep up with the performance predictions of Moore's law, hardware vendors have had to turn to multi-core computers. Today, parallel hardware is everywhere, from massive server halls to the phones in our pockets. However, this parallelism does not come for free. LÄS MER

  4. 18. Non-blocking Synchronization: Algorithms and Performance Evaluation

    Författare :Yi Zhang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The thesis investigates non-blocking synchronization in shared memory systems, in particular in high performance shared memory multiprocessors and real-time shared memory systems. We explore the performance impact of non-blocking synchronization in high performance shared memory multiprocessors and the applicability of non-blocking synchronization in real-time systems.

  5. 19. Dynamic Adaptations of Synchronization Granularity in Concurrent Data Structures

    Författare :Kjell Winblad; Konstantinos Sagonas; Erez Petrank; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; concurrent data structures; contention adapting; range queries; lock-freedom; adaptivity; linearizability; ordered sets; maps; key-value stores; concurrent priority queues; relaxed concurrent data structures; locks; delegation locking; Computer Science; Datavetenskap;

    Sammanfattning : The multicore revolution means that programmers have many cores at their disposal in everything from phones to large server systems. Concurrent data structures are needed to make good use of all the cores. Designing a concurrent data structure that performs well across many different scenarios is a difficult task. LÄS MER
