China SIG activities update Guoqing Li, Zhenchun Huang Presented in WGISS24, Munich Contents Grid Architecture Update SIG Container Update WAG Activities Other Approaches Grid TestBed Architecture Update Data Resources Computation Resources SIG Container 2.0 Glite 1.2 Application Middleware Application Middleware Application SIG SIG-A 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 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) Globus Toolkit gLiteGOS General grid middlewares Servlet Container such as Tomcat or Websphere SIGRE Spatial applications 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) 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) WAG activities InterGrid Frameworks China Resource SIG-A SIG EGEE Element Connection ESA/GPOD EUChinaGrid II CAT-1 TeraGrid/SRB W-S Grid Agent China/GOS Methodology of InterGrid implementation Web-Service Grid Agent Element level interconnection Agent Service Grid A Grid B Service AService B Grid A Grid B Service AService B Storage element China+US SIGTeraGrid (SRB) SIG SRB SIG2SRB Agent SRB2SIG Agent Finished by RSGS Undertaken by Purdue Univ SIG SRB SIG MCAT SIG Data Register SIG SRB SIG Grid Agents China + EU SIG/GPOD connection (EGEE/Glite) Storage Element SIG-A ESA/GPOD DEM ASAR SE GPOD Flood Analysis ASAR products are stored and processed in ESRIN, DEM are achieved and retrieved from China RSGS using gridftp protocol through Glite SE Orthorectified ASAR WSM products in Vietnam Flood analysis from ASAR WSM taken by ESRIN, severed RSGSs DEM data China + EU (2) EUChinaGrid II RSGS + ESA have joined the work of EUChinaGrid II, in charge of the field of EO application EGEE EGEE-II EUChinaGrid EUChinaGrid II FP6 FP7 A global EGEE e-Infrastructure EUIndiaGrid EUMedGrid SEE-GRID EELA BalticGrid EUChinaGrid OSG NAREGI Glite based Grids EU SideChina Side Glite based Grids GOS Grids Adaptor EUChinaGrid InterGrid Connection Methodology CA China + International CAT-1: WAG testbed (see Natalias report on CAT-1) Call for attendees China-Europe Workshop on Earth Observation Grid Technology and Next Generation Spatial Information Infrastructure Hosted by: NRSCC/China Duration: Dec 3rd ~ 4th Location: Beijing, China Detail information can be accessed from Guoqing LiWelcome to join it.
