Component-based grid environment for programming scientific applications

Programming grid applications still remains a challenging problem due to
distributed and heterogeneous environment, which is not under single
administrative control. Key means for building an environment which will
facilitate programming of grid application are choosing the programming
model and a virtualization mechanism.

After analysis of possible programming models, the component model was
chosen, and specifically CCA standard as most appropriate for scientific
applications. As a virtualization layer the H2O resource sharing
platform was selected. H2O provides a Java-based
lightweight access to shared resources featuring dynamic code
deployment, communication library and security solutions.

Requirements for the component environment were identified, such as
scalability to environments of various level of coupling, facilitated
deployment on shared resources, multiple programming language support,
enabling declarative and imperative programming paradigms, adaptivity to
unreliable environment and interoperability with other existing and
emerging standards such as Web services and GCM.

These requirements were starting point for development of a concept of
component-based approach to programming and deployment of grid
applications, and next i was implemented as a grid environment.
The proposed environment was verified by a prototype implementation
called MOCCA and tested on sample applications in real grid environment.
