1. 36. 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

3. 37. Scientific computing on hybrid architectures

   Författare :Marcus Holm; Sverker Holmgren; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

   Sammanfattning : Modern computer architectures, with multicore CPUs and GPUs or other accelerators, make stronger demands than ever on writers of scientific code. As a rule of thumb, the fastest, most efficient program consists of labor-intensive code written by expert programmers for a certain application on a particular computer. LÄS MER

4. 38. Parallelism and efficiency in discrete-event simulation

   Författare :Pavol Bauer; Stefan Engblom; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

   Sammanfattning : Discrete-event models depict systems where a discrete state is repeatedly altered by instantaneous changes in time, the events of the model. Such models have gained popularity in fields such as Computational Systems Biology or Computational Epidemiology due to the high modeling flexibility and the possibility to easily combine stochastic and deterministic dynamics.

   Sammanfattning : The advent of multicore systems spurred great interest in Transactional Memory (TM). TM is a parallel programming paradigm that coordinates concurrent threads by incorporating transactions into programming languages. LÄS MER

7. 40. 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.
