Avaliação e implementação de uma variação do protocolo TCP, projetada para redes de alto desempenho, visando à distribuição de objetos multimídia nas unidades de armazenamento do servidor Rio
The objective of this work was to study the behavior variations of the TCP protocol that were designed to perform in high speed networks. For this, we investigated if the TCP can become advantageous, in relation to UDP, ... -
Escalonamento estático de tarefas em ambientes computacionais heterogêneos sob o modelo logP
| Posted on: 20 nov. 2004Numerous applications require more performance than event state-of-the- art sequencial computers can provide in order to be executed in acceptable time frames. With high costs of acquisition and maintenance of supercomputers, ... -
HLogP: um modelo de escalonamento para a execução de aplicações MPI em grades computacionais
| Posted on: 21 dez. 2004In order to execute MPI applications efficiently in grid environments, MPI processes need to be allocated appropriately the resources available. Devising efficient process allocations requires a scheduling model which is ... -
Integração de serviços de monitoração e descoberta de recursos a um suporte para arquiteturas adaptáveis de software
| Posted on: 24 nov. 2006Ubiquitous, pervasive and self-adaptive distributed systems have specific requirements regarding the resources to be used by the infrastructure or by the components of the applications. Morover, auto-adaptive, ubiquitous ... -
MyEasyGridPortal: uma abordagem para facilitar o acesso a múltiplas grades computacionais usando a tecnologia Portlet
| Posted on: 20 dez. 2006The falling costs and steady increases in processing capacity and data storage of personal computer, as well as throughput improvements on local networks have stimulated the idea of using such non-specialized computers to ... -
Proposta e análise de um algoritmo adaptativo de ajuste de taxa de transmissão para sistemas VoIP
| Posted on: 15 abr. 2007With the economic benefits over conventional telephone communications, and the potential to offer new classes of services, Voice over IP (VoIP) has been attracting increasing commercial and academic interest. Currently ... -
Sinapse: um arcabouço para suporte e aplicações publish/subscribe baseado em configuração arquitetura
The Publish/Subscribe paradigm implemented by Notification Systems, plays an important role in the context of distributed systems development, allowing the decoupling of the participants due to its anonymous and asynchronous ... -
