A Taxonomy of Grid Resource Brokers*

Grid computing has gone through some generations and as a result only a few widely used middleware architectures remain. Using the tools of these middlewares, various resource brokers have been developed to automate job submission over different grids. Most of the present brokers operate only on a single grid infrastructure, where they have been developed. This taxonomy helps identifying and categorizing the most important properties of brokers within different Resource Management Systems. The result of this work reveals the differences of the examined Resource Brokers, which can enhance a more efficient grid usage and future development.
