According to the integrated technology of NetSolve and Web services,this paper gives services-oriented computing grid middleware architecture,and embeds the 3-layers function architecture of computing grid middleware in it.

0, design a new computing grid framework based on the computing grid distribute middleware, formulation of computing grid distribute middleware protocol, develop the computing grid distributed middleware.

The research on grid middleware of remote sensing data access and integration attempts to provide standard interfaces to access distributed and heterogeneous remote sensing data,and to make the isolated remote sensing data be shared between each other.

It presents a grid portal component architecture based on the grid middleware and the portlet architecture,and then introduces the detailed design of four component modules which are grid security,information service,task management,and file management.

SAGE(ShanghaiGrid Adaptive Grid Engine)is a pure C++ distributed grid middleware we implemented.

It introduces the architecture and the operational principle of NetSolve which is a kind of grid-middleware and discusses the basic process of building a numerical computational grid.
