Efficient resource management for running multiple concurrent jobs in a computational grid environment

摘要

Managing resources in Grid is an intricate issue and is not possible at the application or user level. Grid provides uniform access to heterogeneous resources owned by multiple organizations. Any time a new resource can join the Grid or an existing resource can withdraw. The system loads and status of the resources also change frequently. Thus, a resource broker is an essential component in a Grid environment that can assist in the selection of a right resource provider for a job in all aspects. This paper discusses the design and implementation of resource brokering strategies within the multi-agent framework. These strategies help in finding out an optimal allocation of resources for executing multiple concurrent jobs in a Grid environment. Different stages in resource brokering and their implementation within the framework are discussed. The paper also presents results of evaluating the strategies and demonstrates their effectiveness.
