Este artigo tem como objetivo apresentar as idéias para o desenvolvimento de um framework para balanceamento de carga chamado GetLB. Considerando o contexto de transferência eletrônica de fundos (TEF), GetLB oferece uma nova forma de organizar as interações entre o chaveador e as máquinas processadoras. Esta organização permite que o chaveador combine informações atualizadas para [...]
Today, BSP (Bulk-Synchronous Parallel) represents one of the most used models for writing tightly-coupled parallel programs. A BSP application is divided in one or more supersteps, each one ending with a synchronization barrier. As resource substrates, commonly clusters and eventually computational grids are used to run BSP applications. In this context, we investigate the use [...]
This article aims to present the first ideas for developing a framework for load-balancing called GetLB. Considering the electronic funds transfer (EFT) context, GetLB offers a new scheduling heuristic that optimizes the selection of Processing Machines to execute transactions in a processing center. Instead of using the Round-Robin typical approach, the proposal combines data from [...]
A elasticidade é, sem dúvida, uma das características mais marcantes da computação em nuvem, sendo um diferencial desse tipo de sistema distribuído em relação a outros, como grades computacionais e peer-to-peer. Com base nos paradigmas de computação sobre demanda e pague-pelo-que-use, é possível dinamicamente aumentar ou diminuir instâncias de máquinas virtuais e/ou nós de computação, [...]
Both the size and the resolution of images always were key topics in the graphical computing area. Especially, they become more and more relevant in the big data era. We can observe that often a huge amount of data is exchanged by medium/low bandwidth networks or yet, they need to be stored on devices with [...]

Electronic Funds Transfer represents an upward trend, which fosters the proximity among consumers and suppliers. Each transaction is sent to a Computer Center, in charge of decoding, processing and returning the results as fast as possible. Particularly, the present article covers the GetNet Company day-by-day, focusing on one of their subsystems. In the article, we [...]
