Search computing focuses on building answers to complex search queries (for example, "Where can I attend an interesting conference in my field near a sunny beach?") by interacting with a constellation of cooperating search services, and using result ranking and joining as the dominant factors for service composition. The service computing paradigm has so far been neutral to the specific...
Climate Change research is even more becoming a data intensive and oriented scientific activity. Petabytes of climate data, big collections of datasets are continuously produced, delivered, accessed, processed by scientists and researchers at multiple sites at an international level. This work presents the Euro-Mediterranean Centre for Climate Change (CMCC) initiative, discussing data and metadata...
Nowadays production grids such as EGEE, Teragrid, DEISA adopt several tools in order to monitor jobs, check the status of the grid, manage accounting information, etc. Anyway, from the end-user perspective, monitoring the global status of the grid taking into account machines, networks, services, databases, job, etc. is not straightforward, uniform, and tightly coupled. What we present in this paper...
In a growing number of scientific disciplines, large data collections are emerging as important community resources. Data and metadata management exploiting the data grid paradigm is becoming more and more important as the number of involved data sources is continuously increasing and decentralizing. Efficient grid data access services are perceived as mandatory components for data management. In...
Grid portals are web gateways aiming at providing a pervasive and ubiquitous access in grid to computational resources, tools, instruments, datasets and metadata via standard Web protocols. Moreover, they provide enhanced problem solving capabilities to deal with modern, large scale scientific and engineering problems. Data grid management systems are becoming increasingly important in the context...
Data grid management systems are becoming increasingly important in the context of the recently adopted service oriented science paradigm. The Grid Relational Catalog (GRelC) project is working towards ubiquitous, integrated, seamless and comprehensive data grid management solutions to fully address application specific requirements. This paper describes a GRelC based environment for bioinformatics...
Production grids such as EGEE allow scientists and researchers using aggregated computational power and storage resources. Many users/virtual organizations (VOs) e.g., bioinformatics, astrophysics, etc., need relational databases for their experiments. However, the EGEE middleware (gLite) lacks ad hoc software, and other available solutions are not currently suitable for this purpose within a gLite...
