1. 11. Analysis and Optimization of Communication Overheads in Multi-core Architectures

   Författare :Madhavan Manivannan; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; task parallelism; multi-core; cache coherence; runtime systems; sharing patterns; Amdahl’s Law;

   Sammanfattning : The transition to multi-core architectures can be attributed mainly to fundamental limitations in clockfrequency scaling coupled with a slow growth in uniprocessor performance effected by the challengesin exploiting instruction-level parallelism. Consequently, programmers can no longer realize significant performance gains without investing effort into parallelizing applications. LÄS MER

3. 12. Tools for Understanding, Debugging, and Simulation Performance Improvement of Equation-based Models

   Författare :Martin Sjölund; Peter Fritzson; Dirk Zimmer; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Simulation; modelling; debugging; profiling; optimisation; parallelism; Modelica;

   Sammanfattning : Equation-based object-oriented (EOO) modelling languages provide a convenient, declarative method for describing models of cyber-physical systems.Because of the ease of use of EOO languages, large and complex models can be built with limited effort. LÄS MER

5. 14. Adaptive Task Scheduling and Resource Management Techniques for Improving Energy Efficiency on Multi-core Systems

   Författare :Jing Chen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic Voltage and Frequency Scaling DVFS ; Performance Modeling; Energy Efficiency; Runtime System; Power Modeling; Task Scheduling;

   Sammanfattning : The growing impact of energy on operational cost and system robustness becomes a strong motivation for improving energy efficiency in parallel computing systems, in addition to performance. Hardware features such as core asymmetry and Dynamic Voltage and Frequency Scaling (DVFS) aim to provide opportunities for energy-efficient computing. LÄS MER

7. 15. Advances in Task-Based Parallel Programming for Distributed Memory Architectures

   Författare :Afshin Zafari; Elisabeth Larsson; George Bosilca; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel programming; task-based programming; distributed memory system; scientific computing; hierarchical data; hierarchical tasks;

   Sammanfattning : It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. LÄS MER
