1. MPI sobre MOM para suportar log de mensagens pessimista remoto / MPI over MOM to support remote pessimistic message logging
O aumento crescente no número de processadores das arquiteturas paralelas que estão no topo dos rankings de desempenho, apesar de permitir uma maior capacidade de processamento, também traz consigo um aumento na taxa de falhas diretamente proporcional ao número de processadores. Atualmente, as técnicas de tolerância a falhas com recuperação retroativ

2. MultiCluster : um modelo de integração baseado em rede peer-to-peer para a concepção de grades locais / MultiCluster: an integration model based on peer-to-peer protocols for the construction of local grids
As grades computacionais e as redes peer-to-peer (P2P) surgiram como áreas distintas, com diferentes propósitos, modelos e ferramentas. No decorrer dos últimos anos, estas áreas foram convergindo, uma vez que a infraestrutura e o modelo de execução descentralizada das redes P2P provaram ser uma alternativa adequada para o tratamento de questões relaci

3. Sistema para gerência autonômica de grades computacionais
Grid computing technologies are being applied as an affordable method to cluster computational power together. These structures aim to support service applications by grouping devices and shared resources in one large computational unit. However, the management complexity grows proportionally to the number of resources being integrated. From a given point up

4. ProgramaÃÃo paralela de alto nÃvel e eficiente sobre arquiteturas distribuÃdas
New technological paradigms have emerged in high-performance computing since last decade. The consolidation of distributed architectures and the recent advances in the state-of-the-art performance of processor and interconnection networks gave birth to clusters, conventional computer networks that can compete with supercomputers in its niche of applications,

5. Terminal Restriction Fragment Length Polymorphism Data Analysis for Quantitative Comparison of Microbial Communities
Terminal restriction fragment length polymorphism (T-RFLP) is a culture-independent method of obtaining a genetic fingerprint of the composition of a microbial community. Comparisons of the utility of different methods of (i) including peaks, (ii) computing the difference (or distance) between profiles, and (iii) performing statistical analysis were made by

6. Shrinkage-based similarity metric for cluster analysis of microarray data
The current standard correlation coefficient used in the analysis of microarray data was introduced by M. B. Eisen, P. T. Spellman, P. O. Brown, and D. Botstein [(1998) Proc. Natl. Acad. Sci. USA 95, 14863–14868]. Its formulation is rather arbitrary. We give a mathematically rigorous correlation coefficient of two data vectors based on James–Stein s

7. Comparison of five methods for finding conserved sequences in multiple alignments of gene regulatory regions.
Conserved segments in DNA or protein sequences are strong candidates for functional elements and thus appropriate methods for computing them need to be developed and compared. We describe five methods and computer programs for finding highly conserved blocks within previously computed multiple alignments, primarily for DNA sequences. Two of the methods are a

8. EXCAVATOR: a computer program for efficiently mining gene expression data
Massive amounts of gene expression data are generated using microarrays for functional studies of genes and gene expression data clustering is a useful tool for studying the functional relationship among genes in a biological process. We have developed a computer package EXCAVATOR for clustering gene expression profiles based on our new framework for represe
