  1. 1. 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. 2. Adaptive Resource Management Techniques for High Performance Multi-Core Architectures

    Författare :Nadja Holtryd; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cache Partitioning; Bandwidth Partitioning; Resource Management; Performance Isolation; Multi-Core Architectures; Prefetch Throttling;

    Sammanfattning : Reducing the average memory access time is crucial for improving the performance of applications executing on multi-core architectures. With workload consolidation this becomes increasingly challenging due to shared resource contention. Previous works has proposed techniques for partitioning of shared resources (e.g. LÄS MER

  4. 3. Adaptive Microarchitectural Optimizations to Improve Performance and Security of Multi-Core Architectures

    Författare :Nadja Holtryd; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Core Architectures; Bandwidth Partitioning; Prefetch Throttling; Cache Partitioning; Microarchitectural Optimizations; Side-channel Attacks;

    Sammanfattning : With the current technological barriers, microarchitectural optimizations are increasingly important to ensure performance scalability of computing systems. The shift to multi-core architectures increases the demands on the memory system, and amplifies the role of microarchitectural optimizations in performance improvement. LÄS MER

  5. 4. Energy Efficient Task Mapping and Resource Management on Multi-core Architectures

    Författare :Jing Chen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Consumption; Resource Management; Runtime; Dynamic Voltage-Frequency Scaling DVFS ; Predictive Models; Task Scheduling;

    Sammanfattning : Reducing energy consumption of parallel applications executing on chip multi- processors (CMPs) is important for green computing. Hardware vendors have been developing a variety of system features to support energy efficient computing, for example, integrating asymmetric core types on a single chip referred to as static asymmetry and supporting dynamic voltage and frequency scaling (DVFS) referred to as dynamic asymmetry.

  7. 5. Contributions to Simulation of Modelica Models on Data-Parallel Multi-Core Architectures

    Författare :Kristian Stavåker; Peter Fritzson; Erwin Laure; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Modelica is an object-oriented, equation-based modeling and simulation language being developed through an international effort by the Modelica Association. With Modelica it is possible to build computationally demanding models; however, simulating such models might take a considerable amount of time. LÄS MER
