GPGPU Libraries Benchmark
Kula, Michal ; Korček, Pavol (referee) ; Pospíchal, Petr (advisor)
Bachelor´s thesis deals with principles of graphics adaptors work and their using for common calculations by the help of graphics library and bachelor´s thesis deals also with comparing of these libraries. In the bachelor´s thesis, there is explanation of suitability of graphics adaptors usage for different types of calculations, restrictions and efficiency usage of programming method on basis of principles of graphics adaptors work. In the bachelor´s thesis, there are comparisons of graphics libraries Nvidia Cuda and OpenCL, their comparisons both in transfer rates and for simple and complex calculations. Bachelor´s thesis results are interpretations of tests and suitability assessments of utilization of graphics libraries in selected calculations.

Graphics and Video Algorithms in GP-GPU
Kula, Michal ; Polok, Lukáš (referee) ; Zemčík, Pavel (advisor)
This diploma thesis is focused on object detections through general-purpose computing on graphics processor units. There is an explanation of graphics adapters work and basics of their architecture in this thesis. Based on the adapters, there is the effective work in libraries for general-purpose computing on graphics processor units demonstrated in this thesis. Further, the thesis shows the available algorithms for object detection and which ones from them are possible to be effectively parallelized. In conclusion of this thesis, there is a comparison of the object detections speeds to common implementations on classical processors.

Photon Tracing on GPU
Galacz, Roman ; Navrátil, Jan (referee) ; Polok, Lukáš (advisor)
Subject of this thesis is acceleration of the photon mapping method on a graphic card. The photon mapping is a method for computing almost realistic global illumination of the scene. The computation itself is relatively time-consuming, so the acceleration of it is a hot issue in the field of computer graphics. The photon mapping is described in detail from photon tracing to rendering of the scene. The thesis is then focused on spatial subdivision structures, especially to the uniform grid. The design and the implementation of the application computing the photon mapping on GPU, which is achieved by OpenGL and CUDA interoperability, is described in the next part of the thesis. Lastly, the application is tested properly. The achieved results are reviewed in the conclusion of the thesis.

Evolutionary Design of Collective Communications Accelerated by GPUs
Tyrala, Radek ; Dvořák, Václav (referee) ; Jaroš, Jiří (advisor)
This thesis provides an analysis of the application for evolutionary scheduling of collective communications. It proposes possible ways to accelerate the application using general purpose computing on graphics processing units (GPU). This work offers a theoretical overview of systems on a chip, collective communications scheduling and more detailed description of evolutionary algorithms. Further, the work provides a description of the GPU architecture and its memory hierarchy using the OpenCL memory model. Based on the profiling, the work defines a concept for parallel execution of the fitness function. Furthermore, an estimation of the possible level of acceleration is presented. The process of implementation is described with a closer insight into the optimization process. Another important point consists in comparison of the original CPU-based solution and the massively parallel GPU version. As the final point, the thesis proposes distribution of the computation among different devices supported by OpenCL standard. In the conclusion are discussed further advantages, constraints and possibilities of acceleration using distribution on heterogenous computing systems.
