  1. 1. Schemes to Improve the Efficiency of Hardware Transactional Memory Systems

    Författare :Mridha Mohammad Waliullah; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transactional memory; parallel programming; chip-multiprocessor; multiprocessor;

    Sammanfattning : In todays ubiquitous multiprocessor environment parallel programming becomesan important tool to reap the maximum gain. But the traditional lock-based parallelprogramming model is not attracting average programmers as the level of expertiseneeded is very high. LÄS MER

  2. 2. Predictable Real-Time Applications on Multiprocessor Systems-on-Chip

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jakob Rosén; Linköpings universitet.; Linköpings universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Embedded Systems; Real-Time Systems; Predictability; Multiprocessor Systems; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : Being predictable with respect to time is, by definition, a fundamental requirement for any real-time system. Modern multiprocessor systems impose a challenge in this context, due to resource sharing conflicts causing memory transfers to become unpredictable. LÄS MER

  3. 3. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Petros Voudouris; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel; Identical; Multiprocessor; WCET; multicore; DAG; Uniform; Hard; Real-Time; Homogeneous; Dynamic; Unrelated; Makespan; Related; Scheduling;

    Sammanfattning : To use multiprocessors in hard real-time systems, schedulability analysis is needed to provide formally proven guarantees for the timing behavior of the system. Programming models for parallel applications, such as OpenMP, use pragmas to specify parts of the application as parallel tasks, for example, a function or a body of a loop. LÄS MER

  4. 4. Exploiting Fine-grain Parallelism in Concurrent Constraint Languages

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Johan Montelius; Uppsala universitet.; SICS.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Computing Science; Implicit parallelism; Concurrent Constraint Programming; Cache performance; Logic programming; Abstract machine; Parallel execution; Scheduling; Multiprocessor; Shared memory;

    Sammanfattning : This dissertation presents the design, implementation, and evaluation of a system that exploits fine-grain implicit parallelism in concurrent constraint programming language. The system is able to outperform a C implementation of an algorithm with complex dependencies without any user annotations. LÄS MER

  5. 5. Techniques to Reduce Inefficiencies in Hardware Transactional Memory Systems

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Mridha Mohammad Waliullah; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intermediate checkpoint; conflicting address prediction; Bloom filter; conflict resolution; multiprocessor; speculative buffer overflow; parallel programming; 5C model for cache-misses; transactional memory; conflict classification; starvation;

    Sammanfattning : The recent trend of multicore CPUs pushes for major changes in software development. Traditional single-threaded applications can no longer get a sustainable performance boost from this new generation of CPUs that consist of multiple processors (cores). LÄS MER
