1. Distributed memory organization with support for data migration for noc-based MPSOCS / Distributed memory organization with support for data migration for noc-based MPSOCS
The evolution in the deployment of semiconductor technology has enabled the development of System-on-Chip (SoCs) that integrate several processing elements (PEs) and memory modules in a single chip. SoCs that integrate several PEs are referred as Multiprocessor System-on-Chip (MPSoCs). As the number of PEs increases in an MPSoC, techniques that present low e

2. SHARED-GM: Arquitetura de Memoria Distribuıda para o Ambiente D-GM. / SHARED-GM: DISTRIBUTED MEMORY ARCHITECTURE FOR D-GM ENVIRO
O recente avanco das tecnologias de computadores impulsionaram o uso de clusters de computadores para execuc ao de aplicac oes que exijam um grande esforco computacional, tornando esta pratica uma forte tendencia atual. Acompanhando esta tendencia, o Ambiente D-GM (Distributed-Geometric Machine) constitui-se em uma ferramenta compreendendo dois modulos de so

3. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

4. Avaliação de desempenho de método para a resolução da evolução temporal de sistemas auto-gravitantes em dois paradigmas de programação paralela:troca de mensagens e memória compartilhada
In this work it is presented the performance evaluation of a parallel implementation for the sympletic integrator to simulate the temporal evolution of a self-gravitating system. The algorithm of the sympletic integrator was parallelized and the source code was written in the C programming language. Two parallel programming paradigms were employed: message p

5. A COLLABORATIVE MODEL FOR EVENT SCHEDULING USING COROUTINES / UM MODELO DE ESCALONAMENTO COLABORATIVO DE EVENTOS BASEADO EM CORROTINAS
Event oriented systems are becoming present on many domains of applications. Distributed systems and graphical interactive systems are classical examples of environments that adapt well to the concept of event oriented programming. There are also emerging scenarios like cellphone runtime environments. Despite the growing presence on the computational systems

6. Local DNA sequence alignment in a cluster of workstations: algorithms and tools
Distributed Shared Memory systems allow the use of the shared memory programming paradigm in distributed architectures where no physically shared memory exist. Scope consistent software DSMs provide a relaxed memory model that reduces the coherence overhead by ensuring consistency only at synchronization operations, on a per-lock basis. Much of the work in D

7. Um processo Otimizado de produção de mapas da radiação cósmica de fundo em microondas / An optimized process of production of cosmic microwave backgroud radiation maps
The current work describes the optimization and parallelization of the software for the production of Cosmic Microwave Background (CMB) radiation maps in a distributed memory architecture. Initially, the Fortran code was ported to Fortran 90 and to High Performance Fortran (HPF) and run in a SMP (Shared Memory Processor) machine. In order to provide timing i

8. Um ambiente de execução para suporte à programação paralela com variáveis compartilhadas em sistemas distribuídos heterogêneos. / A runtime system for parallel programing with shared memory paradigm over a heterogeneus distributed systems.
O avanço na tecnologia de hardware está permitindo que máquinas SMP de 2 a 8 processadores estejam disponíveis a um custo cada vez menor, possibilitando que a incorporação de tais máquinas em aglomerados de PC s ou até mesmo a composição de um aglomerado de SMP s sejam alternativas cada vez mais viáveis para computação de alto desempenho. O gran

9. Tecnicas de visualização cientifica e computação distribuida em quimica : uma contribuição a quimica computacional
The application of network computing in chemistry was investigated aiming scientifc visualization and distributed computing. For scientific visualization a graphics library capable of high quality 3D rendering was developed using open standards available under the Unix operating system. This library features a depth buffer for hidden line anel surface remova
