  1. 1. Automatic Parallelization of Equation-Based Simulation Programs

    Författare :Peter Aronsson; Peter Fritzson; Christoph Kessler; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy-duty simulation; Parallel computers; Automatic parallelization; Clustering; Computer science; Datavetenskap;

    Sammanfattning : Modern equation-based object-oriented modeling languages which have emerged during the past decades make it easier to build models of large and complex systems. The increasing size and complexity of modeled systems requires high performance execution of the simulation code derived from such models. LÄS MER

  3. 2. Integrated Optimal Code Generation for Digital Signal Processors

    Författare :Andrzej Bednarski; Christoph Kessler; Alain Darte; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instruction-level parallelism; integrated code generation; dynamic programming; instruction scheduling; instruction selection; clustered VLIW architecture; integer linear programming; architecture description language; Computer science; Datavetenskap;

    Sammanfattning : In this thesis we address the problem of optimal code generation for irregular architectures such as Digital Signal Processors (DSPs).Code generation consists mainly of three interrelated optimization tasks: instruction selection (with resource allocation), instruction scheduling and register allocation.

  4. 3. Performance-aware Component Composition for GPU-based systems

    Författare :Usman Dastgeer; Christoph Kessler; Marco Danelutto; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis addresses issues associated with efficiently programming modern heterogeneous GPU-based systems, containing multicore CPUs and one or more programmable Graphics Processing Units (GPUs). We use ideas from component-based programming to address programming, performance and portability issues of these heterogeneous systems. LÄS MER

  5. 4. Skeleton Programming for Heterogeneous GPU-based Systems

    Författare :Usman Dastgeer; Christoph Kessler; Kristian Sandahl; Sergei Gorlatch; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Skeleton programming; GPU programming; SkePU; performance; portability; Computer science; Datavetenskap;

    Sammanfattning : In this thesis, we address issues associated with programming modern heterogeneous systems while focusing on a special kind of heterogeneous systems that include multicore CPUs and one or more GPUs, called GPU-based systems.We consider the skeleton programming approach to achieve high level abstraction for efficient and portable programming of these GPU-based systemsand present our work on SkePU library which is a skeleton library for these systems.

  7. 5. Towards a Framework for Static Analysis Based on Points-to Information

    Författare :Marcus Edvinsson; Welf Löwe; Joakim Nivre; Christoph Kessler; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Static analysis; Points-to analysis; Framework; Computer science; Datalogi; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Sammanfattning : Static analysis on source code or binary code retrieves information about a software program. In object-oriented languages, static points-to analysis retrieves information about objects and how they refer to each other. LÄS MER
