Grid-based collaboration

摘要: Grids are managed Internet scale distributed services supporting collaboration and virtual organization. Collaboration over networks is becoming more popular important in such areas as online conferencing, distance education, e-Science, e-Business, e-Learning. We research the topic of shared event on Grid; we build three prototypes to investigate issues from different software models languages; demonstrate this by making clients (collaboration entities) collaborate events, taking advantages Grid for delivery messages computing powers clients' host computers. built Web Services exchanging messages.
