ChinaGrid provides the nationwide grid computing platform and services for education and research purpose among 100 key universities in China. University digital museum grid (UDMGrid) is one of the most important applications of ChinaGrid which aims at offering one-stop information services about kinds of digital specimens from several university digital museums in the form of grid services. During last 3 years, many versions of UDMGrid have been developed. This paper describes the progress of UDMGrid and presents key technologies of the current version such as ontology, Grid-DAI and grid monitoring. Finally, the workflow of UDMGrid is given

Workflow management technologies play a very important role in constructing grid application environment by automating service composition and execution. With the fast spread of grid technology, workflow management system should be flexible to meet increasing requirements of service composition. This paper introduces a distributed workflow management approach DWM4CGSP named distributed workflow management for CGSP, which can improve capability of workflow execution by dynamically assimilating new workflow engines and balancing workload among these engines. Moreover dynamic load balancing is applied in DWM4CGSP in order to make workload on each engine at reasonable level. Finally an implementation demonstrates that DWM4CGSP works well in CGSP and can be further extended to other similar grids

To allow geographical dispersed engineers to perform an assembly task together, a virtual environment for collaborative assembly (VECA) has been developed to build a typical collaborative virtual assembly system. This presents the key parts of VECA, such as system architecture, HLA-based (high level architecture) communication and collaboration, motion guidance based on collision detection and assembly constraints recognition, data translation from CAD to virtual environment, reference resolution in multimodal interaction.
