1. Abordagem adaptativa de monitoramento para escalonamento de grafos dirigidos acíclicos em ambientes distribuídos
O escalonamento estático de um programa, representado por um grafo dirigido acíclico de tarefas, em um ambiente multiprocessado, tem o objetivo de minimizar o tempo de conclusão do programa. Apesar das pesquisas nesta área terem obtido heurísticas eficientes, encontrar um escalonamento ótimo é um problema NP - Completo. Clusters de workstations podem

2. Alocação de Tarefas Paralelas Comunicantes em Ambientes Distribuídos Heterogêneos
Distributed systems have been widely used in the resolution of problems that demand a large amount of processing time, because they allow the simultaneous utilization of many computational resources. Many machines with a distributed architecture have been proposed during the years. Among these are computer clusters, which are distributed systems composed of

3. "Parallel implementation of the exact Euclidean distance transform" / "Implementação paralela da transformada de distância euclidiana exata"
The Euclidean distance transform is the operation that converts a binary image made of object and background pixels into another image, the Euclidean distance map, where each pixel has a value corresponding to the Euclidean distance from this pixel to the background. The Euclidean distance transform has important uses in computer vision, image analysis and r

4. Modelagem e predição de desempenho de primitivas de comunicação MPI. / Performance modeling and prediction of MPI communication primitives.
The development of parallel and distributed programs finds at message-passing programming a powerful approach to explore properly the distributed memory machines issues. Using clusters and message-passing libraries, as MPI standard (Message Passing Interface), efficient and cost effective applications can be constructed. In these systems, the time spent with
