Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. In these environments, the required resources must be accessible for Grid applications on demand, which makes the resource discovery as a critical service. In recent years, various techniques are proposed to index and discover the Grid resource...

Grid technologies enable the sharing of a wide variety of distributed resources. To utilize these resources, effective Resource Management systems are needed. Resource Management system performs resource discovery to obtain information about the available resources. However, the complex and dynamic nature of grid resources make sharing and discovery, a challenging issue. Resource Discovery is i...

One of the basic services in the Grid is resource discovery. When a user request services, he gives a set of attributes that should be satisfied by a candidate resource. The resource discovery mechanism returns a set of best resources for the given set of attributes. We present two P2P protocols for resource discovery: the Query Resource Discovery Mechanism (QRDM), and the Seeking Resource Disc...

DSTC Tech Report 34) Resource Discovery is the term commonly used to refer to the exercise of locating, accessing, retrieving, and managing relevant resources (eg information and services) for a user from widely distributed heterogeneous networks. The Resource Discovery Unit of the Research Data Network Cooperative Research Centre is working on tools and technologies which make these tasks easi...

A new type of resource discovery mechanism is proposed for simulation oriented data grid. By introducing distributed resource brokers at edge routers of each domain, a majority of resource discovery queries can be processed solely by resource brokers at edge routers, instead of accessing remote global resource broker. The response time and network overhead of resource discovery is reduced and s...

Grid technologies enable the sharing of a wide variety of distributed resources. To utilize these resources, effective Resource Management systems are needed. Resource Management system performs resource discovery to obtain information about the available resources. The most challenging task in Grid environment is to manage the heterogeneous resources which needs an Automatic Grid Resource Disc...
