Grid Computing

Grid computing is increasingly perceived as the main enabling technology for facilitating multi-institutional and multi-disciplinarycollaborations. By sharing unique resources amongst organizationsand by providing uniform and ubiquitous access to these facilitiesto both scientists and industrial end-users, a new generationof challenges can be addressed.

As clusters of commodity compute systems become more widespread andhigh-speed networks extend to an ever larger part of the community,Grid middleware and grid portal services are deployed at an increasing number of sites in the Netherlands.

David Groep, NIKHEF

The real and specific problem underlying Grid technology – well described by Ian Foster and Carl Kesselman – is coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations.

This sharing involves direct access to computers, software, data, and other on-line resources, as required by a range of collaborative strategies in science, industry and engineering. This sharing is necessarily highly controlled, operating security over the wide-area Internet, with resource operators and users negotiating detailed contracts on what is to be shared, who can use their resources and on conditions of use.

Such a set of individuals and institutions forms the Virtual Organization.

DutchGrid Platform

DutchGrid is the platform for large-scale distributed computing in the Netherlands. Open to all institutions for research and test-bed activities, the goal of DutchGrid is to coordinate the various deployment efforts and to offer a forum for the exchange of experiences on Grid technologies.

DutchGrid Platform collaborators meet regularly, usually at get-togethers organized by of one of the existing Grid projects in the Netherlands: DataGrid, ASCI/DAS-2 and ICES/KIS Virtual Lab. Besides, the platform provides limited hands-on support for organizations seeking to use Grid for their application. This support is provided through collaborations with one of the participating projects.

If you (or your organization) is actively considering to use and deploy Grid services, you are cordially invited to join the DutchGrid Platform. See http://www.dutchgrid.nl/

Some Resources

Grid Protocol Architecture

The Grid protocols define the fundamental way by which applications can `talk’ to the resources. Taking key concepts from the Internet architecture, a small number of resource and connectivity protocols allow different applications to access a diverse range of resource types in the Fabric.
