Abstract
Funding condition
Build a Application-oriented Grid
 CGDP: China Grid Portal of Scientific

Funding Condition
• The first funding closed at the end of
2003.
• Research work has been interrupted
during almost whole 2004
• New funding started from the last
Oct.
2004

2005
Build a Application-oriented Grid
• Because
– Grid have been accepted as important
information utilization and serving
technology.
– Grid research works have been taken
widely in the past two years.
– Many grid tools and grid demo systems
have been finished.
=> Feasibility
RSGS,CAS
• But
– It is difficult to configure a original
data source to be grid services.
– It is also difficult to add new spatial
processing software to be gird-useful
services.
– It is still not easy to mine right data
form grid data resources.
– Even to build a Grid environment is a
very professional operation.
RSGS,CAS
=> Problem in use
• So we will do:
– Feasibility -> Usability.
– Build a Application-oriented Grid
Environment.
– Grid container
• In SIG, will use uniform grid container as
basic middleware and protocols.
– Grid Gateway
• Bring in-LAN resource to be a node of Grid
in form of some services.
