  3. 7. 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.

  4. 8. Real-Time Shading and Accurate Shadows Using GPGPU Techniques

    Författare :Ola Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual shadow-maps; real time; transparency; shading; shadows; rendering; shadow volumes; GPGPU; GPU;

    Sammanfattning : Over the last 10-15 years, computer graphics hardware has evolved at a tremendous pace, with an exponential growth in the number of transistors. This evolution has transformed the Graphics Processing Unit (GPU) from an entirely fixed-function unit into a highly parallel general-purpose architecture that can be programmed using high-level programming languages.

  5. 9. An Automated and Controlled Numerical Precision Reduction Framework for GPUs

    Författare :Alexandra Angerd; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microarchitecture; Floating-Point Precision; Approximate Computing; Register File; GPU;

    Sammanfattning : Reducing the precision of floating-point values is an effective approach to achieve higher performance as well as higher energy-efficiency. This is especially true for GPUs, since many of its common tasks are inherently insensitive to precision-reduction. LÄS MER

  7. 10. Contributions to Parallel Simulation of Equation-Based Models on Graphics Processing Units

    Författare :Kristian Stavåker; Peter Fritzson; Erwin Laure; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelica; GPU; CUDA; OpenCL; Modeling; Simulation;

    Sammanfattning : In this thesis we investigate techniques and methods for parallel simulation of equation-based, object-oriented (EOO) Modelica models on graphics processing units (GPUs). Modelica is being developed through an international effort via the Modelica Association. LÄS MER
