  1. 1. Methods for Creating and Exploiting Data Locality

    Författare :Dan Wallin; Erik Hagersten; Sverker Holmgren; David Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data locality; temporal locality; spatial locality; prefetching; cache; cache behavior; cache coherence; snooping protocols; partial differential equation; shared-memory multiprocessor; chip multiprocessor; simulation; Computer engineering; Datorteknik;

    Sammanfattning : The gap between processor speed and memory latency has led to the use of caches in the memory systems of modern computers. Programs must use the caches efficiently and exploit data locality for maximum performance. LÄS MER

    Författare :Xavier Vera; Björn Lisper; Isabelle Puaut; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : .... LÄS MER

  4. 3. A WCET Analysis Method for Pipelined Microprocessors with Cache Memories

    Författare :Thomas Lundqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; data cache; infeasible paths; pipeline; instruction cache; dynamically scheduled processor; worst-case execution time; timing analysis; path analysis; timing anomaly;

    Sammanfattning : When constructing real-time systems, safe and tight estimations of the worst case execution time (WCET) of programs are needed. To obtain tight estimations, a common approach is to do path and timing analyses. LÄS MER

  5. 4. Towards Runtime-Assisted Cache Management for Task-Parallel Programs

    Författare :Madhavan Manivannan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; task parallelism; cache hierarchy; runtime system; dead blocks; multi-core architecture; sharing patterns;

    Sammanfattning : Architects have adopted the shared memory model that implicitly manages cache coherence and cache capacity in hardware, mainly to aid programmability of multi-core architectures. The hardware mechanisms are however prone to inefficiencies because they are not tailored to the behavior of individual parallel applications. LÄS MER

  7. 5. Improving Energy-Efficiency of Multicores using First-Order Modeling

    Författare :Vasileios Spiliopoulos; Stefanos Kaxiras; Lieven Eeckhout; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; DVFS; Cache Resizing; Interval modeling; Power modeling; Computer Science; Datavetenskap;

    Sammanfattning : 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.
