  1. China SIG activities update Guoqing Li, Zhenchun Huang Presented in WGISS24, Munich 2007-10-16

  2. Contents • Grid Architecture Update • SIG Container Update • WAG Activities • Other Approaches

  3. Grid TestBed Architecture Update Application SIG SIG-A Application Middleware Application Middleware Glite 1.2 SIG Container 2.0 Data Resources Computation Resources

  4. SIG Container Update • SIG Container is updated to version 2.0, and renamed to SIGRE – SIG Runtime Environment • Target of update: SIGRE will be the bridge and isolated area between the general grid middlewares (such as Globus or Glite) and the Spatial applications. So, it should: • More stable • Codes refactored, bugs fixed • More powerful • Data service framework is embedded • WS-Security based user authentification and data encryption • More platform-independent • Distributed as a WAR, can be installed in any servlet container, such as tomcat, websphere, weblogic, … • Will be able to work on many types of grid middleware

  5. SIG Container Update • Target of update: • Easier to install, configure, use and develop • Install: place WAR to webapp folder of servlet container • Configure: by a web-based configure wizard • Use & Develop: (see following) Spatial applications SIGRE General grid middlewares Globus Toolkit gLite GOS …… Servlet Container such as Tomcat or Websphere

  6. Main factors of update • Codes are refactored and bugs are fixed • Only one edition now (old SIG container has 2: lite edition and meta edition) • WS-Security based user authentification and data encryption is supported • Advanced node service take place of old version service, registry service and monitor service • Resource deployment by web-based wizard, need not register again (as in the old SIG container) • Distributed resource discovery support (by the node service)

  7. Main factors of update • Automatically job client stub generation (by SIGRE tools) • Data service framework which supports data query, data access and WMS • On-demand job support (developing) • More general grid middleware supports (developing) • Web-based configuration wizard and management tools (developing)

  8. WAG activities • InterGrid Frameworks ESA/GPOD EUChinaGrid II EGEE Element Connection SIG-A China Resource CAT-1 W-S Grid Agent TeraGrid/SRB SIG China/GOS

  9. Methodology of InterGrid implementation • Element level interconnection • Web-Service Grid Agent Agent Service Storage element Service A Service B Service A Service B Grid B Grid A Grid B Grid A

  12. China + EU • SIG/GPOD connection ASAR SE ESA/GPOD SIG-A (EGEE/Glite) Storage Element DEM GPOD Flood Analysis

  13. ASAR products are stored and processed in ESRIN, DEM are achieved and retrieved from China RSGS using gridftp protocol through Glite SE Flood analysis from ASAR WSM taken by ESRIN, severed RSGS’s DEM data Orthorectified ASAR WSM products in Vietnam http://www.disasterscharter.org/disasters/CALLID_170_e.html

  14. China + EU (2) • EUChinaGrid II • RSGS + ESA have joined the work of EUChinaGrid II, in charge of the field of EO application EGEE-II EGEE EUChinaGrid II EUChinaGrid FP7 FP6
