The Gridbus Project is developed by the University of Melbourne, Australia, and it focuses on the design and development of grid middleware to support eScience and eBusiness applications. In August of 2006, it released a new version (3.0) of their Grid Service Broker that works with WSRF-compliant Grid resources. They claim that this broker manages user access to distributed "autonomous" grid resources by (a) discovering suitable data sources for a given analysis scenario, (b) suitable computational resources, (c) optimally mapping analysis jobs to resources, (d) deploying and monitoring job execution on selected resources, (e) accessing data from local or remote data source during job execution and (f) collating and presenting results.
The broker provides (a) a declarative and dynamic parametric programming model and (b) a rich set of Java APIs for creating grid applications. It also allows programmers to create a user-level scheduler and middleware plugins that can replace default Computational and Data Grid scheduling algorithms that support service price-based resource allocation.
In the new version 3.0, the broker can now be hosted as a remote web service, which is compliant with the WSRF standard.
