           3 The SDG Project
   By Dec. 2002
    – 31 member institutions
    – 217 databases
    – 3.2 TB
   Classification
    –   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.
•LDAP-based Storage.
•Management functions (add, delete, modify and query) ,
back-end is MDIS.

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

     National HEP DataGrid Testbed

 NFSC gives support for HEP application
  testbed.
 there are 2 or 4 universities and IHEP to
  join the project, including PKU, SDU, THU,
  USTC .
 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
     applications.
 –   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
     China.

    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
  one.
