Meta-broker for future generation grids: a new approach for a high-level interoperable resource management

As grid technology matures the number of production grids dynamically increases. The management and the optimal utilization of these grid resources cannot be handled by the users themselves. One very important aspect of utilizing multiple Gridswithin one complex scientificworkflowis to interact with multiple and potentially different grid brokers supported by different Grids. To ease the utilization of different resource brokers, we have introduced a meta-brokering concept to solve grid interoperability. With this new grid middleware component users and portals can utilize a growing number ofGrids simultaneously for highly computation intensive applications in the future
