This thesis, entitled €High Performance Computing for solving large sparse systems. Optical Diffraction Tomography as a case of study€ investigates the computational issues related to the resolution of linear systems o...

En este artículo se presenta una metodología y una herramienta para la instrumentación de programas paralelos en plataformas de cómputo distribuidas con la mayor resolución posible (microsegundos, si fuera posible) ...

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...

We propose an architecture which supports the behavioral self-optimization of complex systems. In this architecture we bring together specification-based reasoning and the framework of ant colony optimization (ACO). By t...

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 rising complexity of distributed computer systems give reason to investigate self-organization mechanism to build systems that are self-managing in the sense of Autonomic and Organic Computing. In this paper we prop...

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...

CSCW is a well-suited discipline for appropriate communicating ideas inside a group and even in an inter-group cooperation. Though basic technology for communication annoy people with too many computer-related tasks to d...

The growing processing power of standard workstations, along with the relatively easy way in which they can be available for parallel processing, have both contributed to their increasing use in computation intensive app...

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 ...

We present ADMP, the adaptive mesh-based multicast routing protocol, in which nodes are able to independently tune the amount of redundancy used to transmit data packets with the goal of improving the overall packet deli...

This paper presents a basic and an extended heuristic to distribute operating system (OS) services over mobile ad hoc networks. The heuristics are inspired by the foraging behavior of ants and are used within our NanoOS...

Sorne questions and problems arise when working with ComponentBased Design. One of these is the abstraction needed to decide suitability of a component for the designo Bisimulation is a relation between the states of two...

Consider a (robotic) explorer starting an exploration of an unknown terrain from its base station. As the explorer has only limited communication radius, it is necessary to maintain a line of robotic relay stations follo...

Parallel performance optimization is being applied and further improvements are studied for parallel linear algebra on clusters. Several parallelization guidelines have been defined and are being used on single clusters ...

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...

It is a fact that gaming technology is a state-of-the-art tool for military training, not only in low level simulations, e.g. flight training simulations, but also for strategic and tactical training. It is also a fact t...

Esta línea de I/D se enfoca en la especificación, desarrollo y evaluación de sistemas paralelos utilizando esquemas multiprocesador. Se parte del estudio de las arquitecturas de múltiples núcleos (multicore) y se tr...

Este trabajo presenta un análisis de la degradación de la red virtualizada, en la ejecución de algoritmos paralelos, para entornos de cómputo científico en un Cloud privado. Se introducen los conceptos básicos de V...

En los últimos años se ha incrementado la complejidad y la heterogeneidad de las redes de datos, por ello, el gerenciamiento de las mismas se vuelve cada vez más complejo e importante. El trabajo de los administradore...

Los avances de la tecnología informática y la baja de costos del equipamiento hicieron realidad, en las últimas décadas, el desarrollo de los sistemas distribuidos. Basados en sistemas seguros de comunicación y com...

Como ocurrió con Internet, una vez más es la ciencia la que inicia el camino de nuevas tecnologías. La necesidad de ejecutar aplicaciones que requieren una gran capacidad de procesamiento, condujo tanto al afianzamien...

La tecnología Grid ha logrado insertarse en el mundo científico y en estos momentos se comienzan a ver implementaciones también en el mundo de negocios, debido al proceso de evolución de esta tecnología en los últi...
