HPSM: uma API em linguagem c++ para programas com laços paralelos com suporte a multi-CPUs e Multi-GPUs / HPSM: a c++ API for parallel loops programs Supporting multi-CPUs and multi-GPUs

Di Domenico, Daniel 21 December 2016 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Parallel architectures has been ubiquitous for some time now. However, the word ubiquitous can’t be applied to parallel programs, because there is a greater complexity to code them comparing to ordinary programs. This fact is aggravated when the programming also involves accelerators, like GPUs, which demand the use of tools with scpecific resources. Considering this setting, there are programming models that make easier the codification of parallel applications to explore accelerators, nevertheless, we don’t know APIs that allow implementing programs with parallel loops that can be processed simultaneously by multiple CPUs and multiple GPUs. This works presents a high-level C++ API called HPSM aiming to make easier and more efficient the codification of parallel programs intended to explore multi-CPU and multi-GPU architectures. Following this idea, the desire is to improve performance through the sum of resources. HPSM uses parallel loops and reductions implemented by three parallel back-ends, being Serial, OpenMP and StarPU. Our hypothesis estimates that scientific applications can explore heterogeneous processing in multi-CPU and multi-GPU to achieve a better performance than exploring just accelerators. Comparisons with other parallel programming interfaces demonstrated that HPSM can reduce a multi-CPU and multi-GPU code in more than 50%. The use of the new API can introduce impact to program performance, where experiments showed a variable overhead for each application, that can achieve a maximum value of 16,4%. The experimental results confirmed the hypothesis, because the N-Body, Hotspot e CFD applications achieved gains using just CPUs and just GPUs, as well as overcame the performance achieved by just accelerators (GPUs) through the combination of multi-CPU and multi-GPU. / Arquiteturas paralelas são consideradas ubíquas atualmente. No entanto, o mesmo termo não pode ser aplicado aos programas paralelos, pois existe uma complexidade maior para codificálos em relação aos programas convencionais. Este fato é agravado quando a programação envolve também aceleradores, como GPUs, que demandam o uso de ferramentas com recursos muito específicos. Neste cenário, apesar de existirem modelos de programação que facilitam a codificação de aplicações paralelas para explorar aceleradores, desconhece-se a existência de APIs que permitam a construção de programas com laços paralelos que possam ser processados simultaneamente em múltiplas CPUs e múltiplas GPUs. Este trabalho apresenta uma API C++ de alto nível, denominada HPSM, visando facilitar e tornar mais eficiente a codificação de programas paralelos voltados a explorar arquiteturas com multi-CPU e multi-GPU. Seguindo esta ideia, deseja-se ganhar desempenho através da soma dos recursos. A HPSM é baseada em laços e reduções paralelas implementadas por meio de três diferentes back-ends paralelos, sendo Serial, OpenMP e StarPU. A hipótese deste estudo é que aplicações científicas podem valer-se do processamento heterogêneo em multi-CPU e multi-GPU para alcançar um desempenho superior em relação ao uso de apenas aceleradores. Comparações com outras interfaces de programação paralela demonstraram que o uso da HPSM pode reduzir em mais de 50% o tamanho de um programa multi-CPU e multi-GPU. O uso da nova API pode trazer impacto no desempenho do programa, sendo que experimentos demonstraram que seu sobrecusto é variável de acordo com a aplicação, chegando até 16,4%. Os resultados experimentais confirmaram a hipótese, pois as aplicações N-Body, Hotspot e CFD, além de alcançarem ganhos ao utilizar somente CPUs e somente GPUs, também superaram o desempenho obtido por somente aceleradores (GPUs) através da combinação de multi-CPU e multi-GPU.

Propojení knihovny pro zpracování obrazu s jazykem Lua / Image processing library wrapper for Lua

Prymus, Jiří January 2012 (has links)
The thesis deals with OpenCV library and its implementation into scripting language Lua. The first part of the thesis concentrates on description of the course Computer vision MPOV and description of mathematical basics needed for further understandings. The second part describes OpenCV library and its potential usage in the MPOV. Next chapter examines the programming scripting language Lua. The description of the implementation of binding the OpenCV library to Lua language along with its overall functionality is included in the practical part of the thesis. The use of LuaCV is more comfortable thanks to Open Source projects for cross-platform compilation and distribution. Part of the thesis is also generator of Latex documentation for LuaCV binding. The last chapter deals with testing LuaCV in course MPOV and analysis of criticism from students.
