Overview of Grid
Projects in China
1 The VEGA Project
Design and implement Grid level system
Grid oriented super-server—the Dawning
Service Grid—Providing various services to
users, for instances, computation,
messaging, knowledge services.
Architecture, Grid Operating system,
application development, etc.
Vega Grid Architecture
Grid browser Resource router Grid server
Global Grid batch system.
Applications based on the GOS APIs.
No center control.
Shell commands: gsub, gstat, gkill, etc.
All registered resources are available for
users, CPU, disk spaces, networks, data,
Global Batch System in Vega
On-line Transaction System
4 different basic services registered to Grid.
- Whether forcasting.
- Airline ticket booking.
- Sigh spot ticket booking.
Put these services into a special application.
AN Online Transaction
2 The China National Grid
The National High Performance Computing
A key 863 programme (MOST).
Including 9 sites for HPC in the Grid.
- Interconnected them with available
networks ( Cernet & NSTnet)
- equipped each site with
Dawning 2000/3000, Galaxy 3(20Gflops),
Sunway 1(460Gflops), PC-cluster(8Gflops).

3 The SDG Project
By Dec. 2002
– 31 member institutions
– 217 databases
– 3.2 TB
– numerical: 46%
– text: 18%
– spatial: 22%
– multimedia: 14%
SDG Universal Metadata Too
• many disciplines in SDG similarly many or more
metadata standards. it’s not good for us to develop a tool
for every metadata schema individually.
•input metadata for existing databases is more bothersome,
so a ease-to-use tool might be in practice.
•input: a metadata schema (xml DTD).
•output: Web-based, customizable UI.
•Management functions (add, delete, modify and query) ,
back-end is MDIS.
SDG Universal Metadata Tool
install & MD schema
XML page User
-metadata is tree-like and more flexible than fix-column tables, difficult to
deal with on web UIuse xml files to store interim results
-use xml files to store interim results
– Astronomical data is huge & well documented
– Most is online & sharable
– So, Internet is becoming the world’s best
– Data integration and federation
(by many different instruments from many
different places and many different times)
– Ease-to-use for astronomers
– LAMOST (aperture: 4m, by 2004)
– Collaboration between
NAO and CNIC
4 The China Grid
it is being proposed now, and will be
founded by MOE ( the Ministry of
Education), It’s bandwidth is 2.5Gbps,
connect 100 universities across China.
And to be inter-connected to NFSCNET.
Discussion is under way, When? How?
5 HEP DataGrid in China
(1) BES experiment: the tau-charm
physics International collaboration with
18 domestic universities and 4 foreign
The major upgrade program BEPCII has
been approved by Chinese Government.
Increasing Luminosity by a factor of
produce about 3 PB data in 3-5 years.
(2) YangBaJing Cosmic-ray Lab. At
China-Japan collaboration: air-
shower array detector since 1990
China-Italy collaboration: RPC carpet
detector of 10000 m2 , under
several domestic and foreign
universities participate in both
Data Volume: about several
hundreds of TB data.
(3)Experiments of LHC: CMS and Atlas
- China physicists are participating in
MC simulations, and will participate
in physics analysis.
- build Tier-2 Regional Center at least.
- NSFC delegation visited CERN to
discuss the collaboration in April
(4) Belle and Babar
(5) Alpha Magnetic Spectrometer
The IHEP Campus Grid
Building a Campus Grid Computing
Environment at IHEP).
Making full use of 7 PC Farms built at IHEP,
which run separately for various
experiments which leads to inefficient
utilization of these PC Farms.

NFSC gives support for HEP application
there are 2 or 4 universities and IHEP to
join the project, including PKU, SDU, THU,
Fund about 1.5million CNY (near 20USD).
Hopefully, it is able to enhance the
international collaboration of China.
The On-going and Future Work
– Develop the Web-based portal of HEP
and Web services in China.
– And Develop various HEP Grid-enabled
– Make proposal for building HEP DataGrid
across China and join Lambda ring or the
like as a node.
– And Regional Center Tier-2 for
collaboration CMS and ATLAS of LHC in

The Grid Prospect in China
NFSC organized the relevant officials and
scientists to visit CERN, and seek the roadmap of
grid development in China.
And recently computer scientists and physicists ….
sit down together to discuss how to move the
China grid projects forwards(organized by NFSC).
Conclusion is China should concentrate on Grid-
based applications at first, and a few of nationwide
testbeds need to be built, the first is HEP DataGrid
