Grid meta-broker architecture: towards an interoperable grid resource brokering service

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 different resource brokers have been developed to automate job submission over different grids. As grid resources were grouped to Virtual Organizations, users seem to become isolated by these groups. Enhancing interoperability among these VOs and grids will be the main issue of future generation grids. This paper describes a meta-brokering architecture that shows how to enable the interoperability of various grids through their own resource brokers
