  1. 1. Techniques to Reduce Thread-Level Speculation Overhead

    Författare :Fredrik Warg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer architecture; multithreaded processors; performance evaluation; speculation overhead; thread-level speculation; chip multiprocessors;

    Sammanfattning : The traditional single-core processors are being replaced by chip multiprocessors (CMPs) where several processor cores are integrated on a single chip. While this is beneficial for multithreaded applications and multiprogrammed workloads, CMPs do not provide performance improvements for single-threaded applications. LÄS MER

  3. 2. Design and Implementation of Thread-Level Speculation in JavaScript Engines

    Författare :Jan Kasper Martinsen; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallel computation; web applications; thread-level speculation;

    Sammanfattning : Two important trends in computer systems are that applications are moved to the Internet as web applications, and that computer systems are getting an increasing number of cores to increase the performance. It has been shown that JavaScript in web applications has a large potential for parallel execution despite the fact that JavaScript is a sequential language. LÄS MER

  5. 4. Evaluating JavaScript Execution Behavior and Improving the Performance of Web Applications with Thread-Level Speculation

    Författare :Jan Kasper Martinsen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis addresses two issues: (i) The execution behavior of JavaScript in established benchmarks and in real-world Web Applications and (ii) whether Thread-Level Speculation is a suitable technique for taking advantage of multicore systems in Web Applications written in JavaScript. The first key result is that JavaScript execution behavior by the benchmarks and the JavaScript execution behavior by the Web Applications differ in several important aspects. LÄS MER
