  1. 1. Performance Modeling of Multi-core Systems : Caches and Locks

    Författare :Xiaoyue Pan; Bengt Jonsson; David Whalley; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; performance modeling; performance analysis; multi-core; cache; lock;

    Sammanfattning : Performance is an important aspect of computer systems since it directly affects user experience. One way to analyze and predict performance is via performance modeling. In recent years, multi-core systems have made processors more powerful while keeping power consumption relatively low. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Studies of magnetic multi-core nanoparticles for biomedical applications

    Författare :Vincent Schaller; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Metropolis algorithm; magnetic bioseparation; Monte Carlo method; Brownian dynamics; magnetic immunoassays; Magnetic multi-core nanoparticles; digital microfluidics; electrowetting-on-dielectric EWOD ;

    Sammanfattning : In recent years, there has been growing interest in using magnetic multi-core nanoparticles in biomedical applications, and particularly in bioseparation and biosensing. In this thesis, two computer simulation techniques have been implemented to study the magnetic response of these particles, and a microfluidic platform has been fabricated to manipulate bio-functionalized magnetic particles in suspension for immunoassays.
