Study And Application Of Grid Information Service

Grid-based integration and management of Grid distribution of resources Grid realize the full resource sharing and collaborative work has become a hotspot. But in the grid environment, in order to realize various applications, it must get the grid state information resources immediately. Grid information services mainly find information, information registration, search information, modify information, and provide grid various hardware resources and services of a true, real-time dynamic response in the grid computing environment. As the grid environment resources are under the wide geographical distribution, and they have large quantities of types, and are always changing, and the different platforms have different resources management strategy, so researching on grid information services is a more meaningful and challenging work.This Paper is all about grid information service. First introduce the definition of information service and its requirement to make sure the importance of information service. Further analyze the service-oriented architecture SOA, Web service, OGSA framework and WSRF and relationship between them, explore the Ganglia monitoring system. The discussed in detail by the Grid information system structure and function. Then discussed in detail by the Grid information system structure and function, Comparative analysis of existing information services mesh models and research the Globus information services component role. Then by summing up a based on GT4 grid information service system based on the model and technology .The system functional modules with the basic information service functions, such as find information, information registration, search information and modify information. The system builds on the latest Globus WSRF technical specifications, and their implementation on the basis of GT4, it has good information grid index and query performance to users with both the release of information resources, also support information inquiries and further information collection or data mining.
