It evolves from theearly five levels hourglass model architecture. OGSA consists of two key technologies: grid technology and Web Ser-vice technology. OGSA gives emphasis to services and all things in OGSA are services. After explaining the basic ideaof OGSA,this paper introduces the composition of OGSA-based hosting environment and virtual organization. Todemonstrate the process of how an application is executed in an OGSA-based environment,the paper gives an exampleof data mining which illustrates the basic functions and working mechanism of OGSA. A brief comparison to relatedgrid architecture is also given in the paper. The paper concludes that OGSA is not mature and it needs improvementtogether with related technology and grid applications.展开更多

Nevertheless, resource management in MG is much more complicated than that in other grid applications due to the geographically distributed manufacturing resources, which range from CAD, CAPP and CAE to various kinds of machine tools. With the interaction of manufacturing grid information service (MGIS, developed by ourselves) and globus resource allocation manager (GRAM, provided by GT3), a resource management framework is presented to perform the functions of resource encapsulation, registry, discovery and monitoring. Furthermore, the application architecture and an example are depicted to illustrate the utilization of the resource management system.展开更多
