  1. 1. Parallelism in Constraint Programming

    Author : Carl Christian Rolf; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Parallelism; Constraint Programming; Parallel Consistency; Parallel Search; Distributed Constraint Programming;

    Abstract : Writing efficient parallel programs is the biggest challenge of the software industry for the foreseeable future. We are currently in a time when parallel computers are the norm, not the exception. Soon, parallel processors will be standard even in cell phones. READ MORE

  2. 2. Architecture Support and Scalability Analysis of Memory Consistency Models in Network-on-Chip based Systems

    Author : Abdul Naeem; Axel Jantsch; Zhonghai Lu; Jari Nurmi; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Memory consistency; Protected release consistency; Distributed shared memory; Network-on-Chip; Scalability;

    Abstract : The shared memory systems should support parallelization at the computation (multi-core), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. These parallel systems supporting shared memory abstraction both in the general purpose and application specific domains are confronting the critical issue of memory consistency. READ MORE

  3. 3. Efficient Execution Paradigms for Parallel Heterogeneous Architectures

    Author : Konstantinos Koukos; Stefanos Kaxiras; Margaret Martonosi; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupled Execution; Performance; Energy; DVFS; Compiler Optimizations; Heterogeneous Coherence; Computer Science; Datavetenskap;

    Abstract : This thesis proposes novel, efficient execution-paradigms for parallel heterogeneous architectures. The end of Dennard scaling is threatening the effectiveness of DVFS in future nodes; therefore, new execution paradigms are required to exploit the non-linear relationship between performance and energy efficiency of memory-bound application-regions.

  4. 4. Adaptiveness and Lock-free Synchronization in Parallel Stochastic Gradient Descent

    Author : Karl Bäckström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; parallelism; machine learning; Stochastic gradient descent;

    Abstract : The emergence of big data in recent years due to the vast societal digitalization and large-scale sensor deployment has entailed significant interest in machine learning methods to enable automatic data analytics. In a majority of the learning algorithms used in industrial as well as academic settings, the first-order iterative optimization procedure Stochastic gradient descent (SGD), is the backbone.

  5. 5. Parallel Data Streaming Analytics in the Context of Internet of Things

    Author : Hannaneh Najdataei; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clustering; stream continuous data processing; edge computing; Internet of Things; parallelism; elasticity; data analysis; fog computing; scalability;

    Abstract : We are living in an increasingly connected world, where the ubiquitously sensing technologies enable inter-connection of physical objects, as part of Internet of Things (IoT), and provide continuous massive amount of data. As this growth soars, benefits and challenges come together, which requires development of right tools in order to extract valuable information from data. READ MORE
