5. 1 Network Infrastructures for Science and Technology in China • The CSTNET— the China Science and Technology Network - One of the earliest networks in China and the first full-functional interconnection with U.S - 55Mbps international link (upgrade to 100Mbps soon). - Topology as Fig. 1

7. 2 NSFCNET—Natural Science Foundation of China Network • Sponsor: National Science Foundation of China (NSFC) - A test bed for advanced high speed network research, native multicast enabled - 6 main nodes (all in Beijing) CNIC of CAS, THU, PKU, BUAA, BUPT, NSFC - Topology is as Fig. 2.

9. 3 The Internet2 Testbed • Support scientific research, development and test of next generation network. - High-speed connection with VBNS and Abiene (connected to STARTAP in Sep,2000) . - 2.5/10Gbps DWDM Backbone ( dual rings). - Will inter-connect 200 nodes, including 100 universities and 100 institutes.

10. - Networking infrastructure is a part of the effort, the more important is development of applications, particularly grid-enabled applications. - Funding 400 million Yuan (~40M US$).

11. 4 CAINONET—China Advanced Info. Optic Net • A 863-300 key project • self-owned technologies and products for next-generation inter-networks • IP/DWDM，2.5G. • Topology as Fig. 3

13. Overview of Grid Projects in China

15. 1 The VEGA Project • Design and implement Grid level system software. • Grid oriented super-server—the Dawning 4000. • Service Grid—Providing various services to users, for instances, computation, messaging, knowledge services. • Architecture, Grid Operating system, application development, etc.

16. Vega Grid Architecture Grid server Client Grid browser Grid://…… Resource router Grid server Grid server

20. Vega Applications • Case 1 • 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, software, sercices…..

22. On-line Transaction System • Case 2: • 4 different basic services registered to Grid. - Whether forcasting. - Airline ticket booking. - Sigh spot ticket booking. - Charging. • Put these services into a special application.

23. AN Online Transaction

25. 2 The China National Grid • The National High Performance Computing Environment—the NHPCE. • 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).

34. 3 The SDG Project • By Dec. 2002 • 31 member institutions • 217 databases • 3.2 TB • Classification • numerical: 46% • text: 18% • spatial: 22% • multimedia: 14%

35. 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. • LDAP-based Storage. • Management functions (add, delete, modify and query) , back-end is MDIS.

36. MD schema install & configure Process(Java bean) MDIS(LDAP) interim XML User page XML engine universal, extensible customizable SDG Universal Metadata Tool • 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

37. Applications • Virtual Observatory • Astronomical data is huge & well documented • Most is online & sharable • So, Internet is becoming the world’s best telescope • 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 betweenNAO and CNIC

38. 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?

39. 5 HEP DataGrid in China • (1) BES experiment: the tau-charm physics International collaboration with 18 domestic universities and 4 foreign universities. • The major upgrade program BEPCII has been approved by Chinese Government. • Increasing Luminosity by a factor of 100 • produce about 3 PB data in 3-5 years.

40. (2) YangBaJing Cosmic-ray Lab. At Tibet • China-Japan collaboration: air-shower array detector since 1990 • China-Italy collaboration: RPC carpet detector of 10000 m2 , under construction. several domestic and foreign universities participate in both experiments Data Volume: about several hundreds of TB data.

41. (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 this year.

42. (4) Belle and Babar (5) Alpha Magnetic Spectrometer (AMS)

43. 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. • Topology as Fig. • IhepGrid monitoring system. • Rebuilding higher bandwidth connection among these PC Farms.
