Load-balancing EU-DataGrid Resource Brokers

The European DataGrid (EDG)[17] project aims to provide a platform to satisfy the ever-growing demand of high computation and storage requirements across scientific disciplines. Its resource broker is the gateway to a managed set of compute elements for handling the job submission and accounting. In this paper, we present an infrastructure layering on top of the resource brokers for load-balancing job submission requests. The resource broker is abstracted as OGSI compliant services to provide interoperability to heterogeneous submission clients. We demonstrate the use of Javaspace as an information distribution framework for different strategic elements to co-operatively load-balance job submission requests.
