Optimizing resource allocation for multiple concurrent jobs in grid environment

In a dynamic environment like grid, it is difficult to manage resources at application or user level. In order to support application execution in the context of grid, a resource broker is essential and the task of resource brokering in such a heterogeneous, fast changing, distributed environment is non-trivial. In this paper we present the design and implementation of resource brokering strategies within a multi-agent framework. These strategies help in finding out an optimal allocation of resources for executing multiple concurrent jobs in a grid environment. We discuss the different stages in resource brokering and their implementation within the framework. The paper also presents results of a preliminary implementation and demonstrates the effectiveness of our strategies.
