Federation scenarios for experimentally driven research usually involve resources offered by a diverse pool of organizations. Federation can be done by a resource broker, which has no resources of its own. Instead the broker matches customer's requested services and providers resources based on the SLA required by the end-user. The end-user has no knowledge that the broker does not control the resources...
The grid provides mechanisms to share dynamic, heterogeneous, distributed resources spanned across multiple administrative domains. The dynamic nature of resources on computational grids raises the question of an efficient scheduling process, which mainly consists of resource discovery and resource selection. So, appropriate resource discovery and selection mechanism is an important aspect of grid...
In grid environment where resources are generally owned by different people, communities or organizations with varied administration policies and capabilities, managing the grid resources is not a simple task. Resource brokers simplify this process by providing an abstraction layer for users to access heterogeneous resources transparently. However, discovery of grid resources that suits to the user's...
Recently we have proposed a novel approach to utilizing agent teams as resource brokers and managers in the grid. Thus far we have presented an overview of the proposed approach discussed how to efficiently implement the information center, where agent teams advertise their needs and resources. In this paper we focus our attention on the way that user selects agent team that will execute its job....
