Abstract:

The grid technology can bring us a powerful computational environment with global resources sharing. As an important part of Grid Computational Environment, Grid Portal is implemented as a Web portal for users accessing grid resources and performing grid computing through the Internet, First in this p aper, we introduce a general grid platform implementation called Globus. Then, a discussion of the functional requirements for the Grid Computational Po  rtal is given with emphasis on Grid Portal Development Kit （GPDK）. Furthermore, we give an overview of CMAG, the China Meteorologic Aoolication Grid PPortal that is developed using GPDK.

Key words: （grid, grid computational environment, grid portal）
