The D-Grid Initiative (German Grid Initiative) was a government project to fund computer infrastructure for education and research (e-Science) in Germany. It uses the term grid computing. D-Grid started September 1, 2005 with six community projects and an integration project (DGI) as well as several partner projects. == Integration project == The D-Grid integration project intended to integrate community projects. The D-Grid integration project acted as a service provider for the science community in Germany. The project office is located at the Institute for Scientific Computing (IWR) at Forschungszentrum Karlsruhe. The resources to ensure a sustainable Grid infrastructure are provided by four work packages: # D-Grid Base-Software: The major task of this work package is to provide several different middleware packages. These are the Globus Toolkit, UNICORE, LCG/gLite, GridSphere and the Grid Application Toolkit (GAT). The community projects linked together in the D-Grid integration project are supported during the installation, operation and if needed and possible the customisation of the Base-Software. # Deployment and operation of the D-Grid infrastructure: Work package 2 builds up a Core-D-Grid. It was used as a prototype to test the operational functionality of the system. This work package also deals with monitoring, accounting and billing. # Networks and Security: The network infrastructure in D-Grid is based on the DFN Wissenschaftsnetz X-WiN. Work package 3 will provide extensions to the existing network infrastructure according to the needs of Grid middleware used in D-Grid. Further tasks are to build an AA-Infrastructure in D-Grid, develop firewall concepts for Grid environments and set up Grid specific CERT services. # D-Grid project office: The work package is responsible for the integration of community projects into one common D-Grid platform. Work package 4 also deals with sustainability. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「D-Grid」の詳細全文を読む スポンサード リンク
