In the last time the high-performance programming community has worked to look for new templates or skeletons for several parallel programming paradigms. This new form of programming allows to programmer to reduce the ti...

La línea orienta su investigación a Arquitecturas de Sistemas Distribuídos, Sistemas Inteligentes Autónomos, Modelos de Integración de Arquitecturas, Modelos de Interoperabilidad Semántica, Compartición de Conocim...

Interesting real world combinatorial problems are NP-complete and many of them are hard to solve by using traditional methods. However, several heuristic methods have been developed in order to obtain timely suboptimal s...

Implicitly exploitable parallelism for Logic Programming has received ample attention. Defeasible Argutmentation is specially apt for this optimizing technique. Defeasible Logic Programming (DLP), which is based on a def...

Since the early stages of parallel computing, one of the most common solutions to in troduce parallelism has been to extend a sequential language with some sort of parallel version of the for construct, commonly denoted ...

This paper presents a novel method for the analysis and representation of parallel program with MPI. Parallel programs are mapped onto graph-theoretical problems and are represented by DP*Tgraph, extension of T-graphs, t...

El trabajo presenta la investigación y desarrollo de un entorno que permite el acceso remoto a laboratorios multicluster. El resultado es una capa de software de administración que puede ser accedida mediante una aplic...

Este artigo propõe recursos para o escalonamento de objetos distribuídos. Para tanto, são definidos dois mecanismos tidos como centrais para tal: um primeiro que irá realizar a instanciação remota de objetos Java, ...

Caracterizar las arquitecturas multiprocesador distribuidas enfocadas a cluster, grid y cloud computing, con énfasis en las que utilizan procesadores de múltiples núcleos (“multicores”), con el objetivo de modeliz...

Una de las áreas de mayor interés y crecimiento en los últimos años dentro del procesamiento paralelo es la del tratamiento de grandes volúmenes de datos, tales como las secuencias de ADN. El tipo de procesamiento e...

Los clústeres de computadoras para Computación de Alto Desempeño (HPC) permiten acceder a relativamente bajo costo a herramientas que aceleran los tiempos de exploración, diseño, testeo e introducción al mercado de...

Se presenta un trabajo orientado a resolver algunos aspectos del problema de sincronización de relojes en ambientes distribuidos. El objetivo inicial está dirigido a la estimación de rendimiento en estos ambientes, do...

This paper describes two parallel algorithms for the eÆcient processing of relational database transactions and presents a performance analysis of them. These algorithms are built upon the bulk-synchronous parallel mode...

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...

Many parallel applications do not completely fit into the data parallel model. Although these applications contain data parallelism, task parallelism is needed to represent the natural computation structure or enhance pe...

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...

DECK (Distributed Executive Communication Kernel) is a communication layer that provides support for multithreading and fault tolerance support. The approach retained in DECK is close to other distributed communication k...

El objetivo principal de nuestro trabajo es proporcionar mediante una NOW (Networks of Workstations), compuesta por estaciones Unix no dedicadas y heterogéneas, un entorno donde se puedan ejecutar eficientemente tanto a...

Uno de los principales problemas que se presentan en las redes de mediana y gran escala es la dificultad para monitorear y detectar vulnerabilidades que puedan ser explotadas. Tanto los recursos que se comparten en una ...

Sistemas de Tempo Real são aqueles sistemas onde a execução correta não depende apenas dos resultados lógicos da computação, mas também do tempo no qual os resultados são produzidos, ou seja, se ocorre dentro do...

Parallel/distributed programming is a complex task that requires a high degree of expertise to fulfill the expectations of high performance computation. The Master/Worker paradigm is one of the most commonly used because...
