The management of the large scale heterogeneous resources is a critical issue in grid computing. The resource management system (RMS) is an essential component of grids. To ensure the QoS of the upper layer service, it raises high requirement for the performance, fault-tolerance and scalability of RMS. In this paper, we study three typical structures of RMS, including centralized, hierarchical and...
The role of multimedia application in our life has dramatically increased in the last few years. Multimedia streaming is more significant than downloading ways in multimedia applications from bandwidth and delay reasons. Multimedia contents are in nature distributed in nodes of grid. Streaming media are still not well resolved in grid environment. This thesis proposes an agent-based framework for...
Resource discovery plays an important role in Grid. The key of Resource Discovery is organization of all information of resources and the status about systems. In currently deployed Grid systems, the information services used for resource discovery usually have been organized into centralized structure or hierarchical structure, such as China Grid, so such information model is efficient. The reason...
Resource management is critical to the usability and accessibility of grid computing systems. Conventional approaches to grid resource discovery are either centralized or hierarchical, and these prove to be inefficient as the size of the grid system increases. The peer-to-peer (P2P) paradigm has been applied to grid systems as a mechanism for providing scalable range- query and multi-attribute resource...
In grid systems, users may require assurance for completing their jobs on shared resources. Such guarantees can only be provided by reserving resources in advance. In this paper, we introduce an elastic reservation model, where users can query about a resource availability on a given time interval. They can also provide a reservation duration time and/or number of compute nodes needed as soft constraints...
Grid technologies are emerging as the next generation of distributed computing, allowing the aggregation of resources that are geographically distributed across different locations. However, these resources are independent and managed separately by various organizations with different policies. This will have a major impact to users who submit their jobs to the Grid, as they have to deal with issues...
