Grid
Technologies and Tools
GRID represents an approach to the sharing of computing resources, mainly processing power and storage. Unlike distributed and cluster computing, which generally require shared resources to be closely located and managed, grid takes advantage of networks to integrate heterogeneous resources into a single, self-administering virtual computer.The value of grid computing has already been proven through the years as a technology with the ability to make more cost-effective use of a given amount of computer resources, to confront problems that cannot be approached without an enormous amount of computing power, and because it realises that the resources of many computers can be cooperatively and perhaps synergistically harnessed and managed as a collaboration toward a common objective.
Traditionally, grids have been mainly used in the scientific arena, to assist in the processing of extremely large data sets. Increasingly, business data are becoming more like scientific data in volume. Modern mainstream applications all require high performance computing methods, to draw insight from ever - growing masses of data, a task suited to grids. Applications vendors are now incorporating grid functionality into software as standard.
The Server Labs has been actively working in Grid projects for years, with special relevance to the ESA Grids like the one used for the Gaia mission, one of our current projects For more info see the ESA Grid Home Page and ESA Gaia Mission Home Page .
