Immediate Services for the GRID

The OASIS INRIA Sophia Antipolis project has been designing and implementing  ProActive, a Java library for the GRID. In the framework of an active object model, the library features Asynchronous Typed Messages, Future Synchronizations (Wait-by-necessity), Group Communications, Mobility, Security, and a generic component model. At the infrastructure level, XML Deployment Descriptors provide the capacity to deploy on many kind of GRIDs.
In the absence of any syntactical extension, ProActive programmers write standard code. The library is itself extensible by the programmers, using a MOP (Meta-Object Protocol), making the system open for adaptations and optimizations.

The main objective of the research is to study, and propose original and sound solutions, for the integration of  immediate services in such a Grid-oriented platform. Underlying theory of asynchronous distributed objects, such as defined in TDO, should be taken into account. Overall, the work will include conceptual analysis, proposition of models, and practical experiments. The following steps could be followed:

• Analysis of existing models, techniques, and tools for active messages, one-sided messages, etc.
  
• Analysis of the Active Object model of the ProActive library
  
• Proposition of an architecture for safe Immediate Services, or conceptual guidelines to achieve them in a safe manner,
  
• Definition of a framework to achieve this model in ProActive
  
• Programming of a prototype implementation, experiment and benchmarks
