La creciente cantidad de imágenes transmitidas a través de Internet ha llevado al desarrollo de Sistemas de Minería de Imágenes de propósito general. La performance de un SMI depende en gran medida de una rápida y...

En este trabajo se presentan las alternativas y los resultados de rendimiento obtenidos del análisis de las alternativas de paralelización en clusters de nodos con múltiples núcleos. El objetivo final es mostrar si e...

Audio identification consist in the ability to pair audio signals of the same perceptual nature. In other words, the aim is to be able to compare an audio signal with a modified versions perceptually equivalent. To accom...

Vision based applications are present anywhere. A special market is industry, allowing to improve product quality and to reduce manufacturing costs. The vision systems applied to industries are known as machine vision sy...

In parallel systems, a number of measures of performance are not accurate or representative of their functioning. These measures allow to quantify the benefit of parallelism. Very often, programs are designed and tested ...

Since the classical molecular dynamics simulator LAMMPS was released as an open source code in 2004, it has become a widely-used tool for particle-based modeling of materials at length scales ranging from atomic to mesos...

This article describes strategies devised to improve the efficiency of two classical index data structures for parallel textual databases. The design and cost evaluation is effected on top of the bulk-synchronous model o...

Fighting fires is a very risky job, where loss of life is a real possibility. Proper training is essential. Several firemen academies offer courses and programs whose goal is to enhance the ability of fire and emergency ...

The paper presents an analysis of three parallelization structures of the N-queens problem, taking into account N processors. The focus has been set on investigating the adaptation of the architecture structure to the pr...

We are given a nite set of jobs of equal processing times with readiness times and tails and a set of identical processors. The aim is to schedule the given set of jobs on the given set of processors to minimize the tot...

Migration of individuals allows a fruitful interaction between subpopulations in the island model, a well known distributed approach for evolutionary computing, where separate subpopulations evolve in parallel. This mode...

The design of parallel programs requires fancy solutions that are not present in sequential programming. Thus, a designer of parallel applications is concerned with the problem of ensuring the correct behavior of all the...

Data parallelislm is one of the more successful efforts to introduce explicit parallelism to high level programming languages. This approach is taken because many useful computations can be framed in term of a set of ind...

El presente trabajo propone el desarrollo de Algoritmos Evolutivos Multiobjetivos paralelos (parallel Multi-Objective Evolutionary Algorithms- pMOEAs). Varios modelos de paralelización alternativos fueron considerados y...

Este artigo apresenta um estudo sobre a aplicação da análise de complexidade na paralelização de programas em lógica. Inicialmente, o texto descreve a estrutura do módulo Analisador de Complexidade proposto pelo m...

El uso de recursos compartidos en las redes de interconexión de alta performance puede provocar situaciones de congestión de mensajes que degradan notablemente las prestaciones, aumentando la latencia de trasporte y di...

Una de las áreas de mayor interés y crecimiento en los últimos años dentro de la informática es la de procesamiento de imágenes. Abarca distintas etapas que van desde la adquisición de los datos de entrada, el mej...

Se presenta en este artículo la experiencia desarrollada referente a la utilización de múltiples clusters para cómputo paralelo. Inicialmente, se presentan algunas consideraciones importantes en cuanto la instalació...

Este trabalho analisa as dependências de controle em arquiteturas Super Escalares. Neste contexto, este trabalho avalia as limita cões fundamentais do desempenho de processadores pipeline e superescalares dando ênfase...

La búsqueda por similitud consiste en recuperar todos aquellos objetos dentro de una base de datos que sean parecidos o relevantes a una determinada consulta. Este concepto tiene una amplia gama de aplicaciones en área...

Este trabalho apresenta a integração dos modelos ParTy e Granlog. O ParTy (Parallel Types Analyzer) é um interpretador abstrato de tipos. O Granlog (Granularity Analyzer for LOGic programming) é um analisador automá...

In this paper, metrics regarding different architectures for distributed arithmetic based FIR filters in FPGA are presented. Main filter parameters are described as well as diverse design techniques applied: pipelining, ...

Las listas invertidas son estructuras de datos frecuentemente utilizadas como índices para bases de datos textuales. Su propósito es acelerar la resolución de consultas sobre grandes colecciones de texto. Actualmente ...
