Executive Summary

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. To hide the lower level details of grid access, grid portals have been developed. Unfortunately, today's grid portals are typically tightly coupled to one specific grid environment and do not provide multi-grid support. The P-GRADE Portal is a work flow-oriented multi-grid portal with the main goal to support all stages of grid work flow development and execution processes. One very important aspect of utilizing multiple Grids within one complex scientific work flow is to interact with multiple and potentially different grid brokers supported by the different Grids.
