Realistic images can be rendered by simulating light transport with Monte Carlo methods. The possibility to use realistic light sources for synthesizing images greatly contributes to their physical realism. Among existing models, the ones based on environment maps and light fields are attractive due to their ability to capture faithfully the far-field and near-field effects […]

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. Specifically, we present three approaches that all use the idea of having multiple implementations […]

Relativistic hydrodynamics became a very useful tool in high-energy physics after Landau’s application of this theory for explaining data on proton-proton collisions. It’s later application to heavy ion collisions has been very successful in modeling apparent collective behaviour of hot matter produced in such collisions. This work is a part of an effort of the […]

In this thesis we explore how application of graphics processors can accelerate calculations in fluid dynamics. We derive semi-implicit pressure linked equations (SIMPLE) and present SIMPLE method (algorithm) which is used with a great success in calculation of steady flows. Motivation for using graphics processors (GPUs) comes from their ability to significantly shorten execution time […]

Since the invention of electronic computers, their performance has been constantly advanced. The recent progress of micro processors in performance has been mainly achieved by increasing the number of cores on a device, instead of increasing working frequency. In addition, because of increasing of density of semiconductors, not only computational performance but also density of […]

This thesis analyses the energy efficiency of a low-power CPU-GPU hybrid architecture. We evaluate the NVIDIA Ion architecture, which couples an Intel Atom low power processor with an integrated GPU that has an order of magnitude fewer processors compared to traditional discrete GPUs. We attempt to create a system that balances computation and I/O capabilities […]

This dissertation explores just-in-time (JIT) specialization as an optimization for OpenCL data-parallel compute kernels. It describes the implementation and performance of two extensions to OpenCL, Bacon and Specialization Annotated OpenCL (SOCL). Bacon is a replacement interface for OpenCL that provides improved usability and has JIT specialization built in. SOCL is a simple extension to OpenCL […]

A radio interferometer indirectly measures the intensity distribution of the sky over the celestial sphere. Since measurements are made over an irregularly sampled Fourier plane, synthesising an intensity image from interferometric measurements requires substantial processing. Furthermore there are distortions that have to be corrected. In this thesis, a new high-performance image synthesis tool (imaging tool) […]

Depth from Defocus (DFD) suggests a simple optical set-up to recover the shape of a scene through imaging with shallow depth of field. Although numerous methods have been proposed for DFD, less attention has been paid to the particular problem of alignment between the captured images. The inherent shift-variant defocus often prevents standard registration techniques […]

In this thesis we described two frameworks for distributed smartphone computing, one for applications with compute intensive tasks and another one for applications that take contextual sensor information into account. Both frameworks provide a common structure for the development of distributed smartphone applications, thereby extending the possible distribution model options for distributed smartphone applications. Both […]

The work presented in this thesis takes place in a context of growing demand for image and video applications on parallel embedded systems. The limitations and lack of flexibility of current design with parallel embedded systems make increasingly complicated to implement applications, particularly on heterogeneous systems. But Open Computing Language (OpenCL) is a new framework […]
