CGSP’s modules Portal:Grid entry for submitting & monitoring job, querying resources’ info, user management and accouting etc. Grid Developing Environment: a set of toolkits including portal development tools, resource encapsulation tools, programming tools and job generation tools etc. Information Center:the manager of resource & service information Uniform Management:a set of managers including job manager, data center, domain manager and service container. Security:Identity authentication and mapping, service and resource authorization, secure transferring etc.

  6. What Is Vega? • Grid related research thrust (brand) at ICT since 1999 • Founded by MOST, CAS, NSFC, industry People • Grid system software (GOS) 40 • Information Grid software (VIG) 10 • Service Grid software (VINCA) 30 • Basic research and semantic grid (Vega-KG) 30 • Share common philosophy VEGA 110 • Versatile Services • Enabling Intelligence • Global Uniformity • Autonomous Control • Vega Grid Inc. established in 2004 • Software versions 2000 2003 2005 • GOS (started in 1999) 0.5 1.0 2.0 • VIG (started in 1999) 0.6 1.0 2.0 • VINCA (started in 2002) 1.0 2.0 Apps VINCA VIG GOS Resources Ad hoc GT3 WS-I

  11. Vega GOS

  12. Vega GOS and OGSA V1.0 • Vega is an implementation of (part of) OGSA • Vega would like to contribute to OGSA • After implementation and testing (running codes) • Loose coupling • Partner with other groups • Focus on 4 key issues and aim at minimal common requirements • Naming, Process/States, VO, Programming • Vega complements existing grid projects • Focus on implementation architecture, not protocols/services • Use computer systems approach, not middleware or network • Utilize existing software • At Vega GOS kernel level • Apache; OMII, GT4; Commercial • As services • At Vega GOS application level

  13. Security in Vega GOS • End-to-End • From user log-on to physical resource execution • Details are hidden from user/developer • Based on WS-Security • Cert based authentication; Token based authorization & AC; signature Web Other Client uCert uCert uid/pass Agora pCert pCert Portal/Server pCert pCert Grip Container User Res AA uTK uTK uTK pCert pCert pCert pCert uTK uTK uTK uTK Phy Svc Phy SVC Phy SVC Phy SVC

  14. Naming in OGSA and Vega GOS • Vega matches OGSA 3-level naming convention • OGSA Human-Oriented Abstract Address • Vega (EVP) Effective Virtual Physical • OGSA Naming specification must include • Precise definitions and axioms • Syntax and semantics (rough consensus) • Who provides, uses, and maintains such names • Scoping and name/address space • Full Lifecycle • Mapping, resolution, binding • Exception handling • Provision for resources

  15. VO in OGSA and Vega GOS • There is no precise definition of VO in OGSA • Agora is a concrete example of VO (community) • Agora has a precise definition, and it holds • Subjects, objects, context/policies information • Agora-related system services • Agora is persistent and “static” • Application programmer knows the agora concept, but agora does not appear in app codes

  16. Process/States in OGSA and Vega GOS • There is no process concept in OGSA 1.0 • Grip is distributed process in grids environment • A runtime construct representing a subject (a grid user running a grid application) to access and utilize objects (grid resources and services) • Classification of “states” • Session related • Application logic specific • Grid system related • Resource related • Service specific Grip

  18. Vega GOS Roadmap in 2005 • 2004.11 2.0 preview Sample Apps • 2005.2 2.0 alpha • 2005.4 2.0 beta CNGrid Apps • 2005.6 2.0 CNGrid Deploy • 2005.7 2.0 on OMII Other Apps • 2005.11.30-12.3 CI6016 & GCC 2005 Exhibit • www.ict.ac.cn/ci6016

  20. Summary • Grid activities in China are still growing • CGSP started development in 2004 • extends WSRF (GT 3.9), will release V1.0 this year • Vega started in 1999 • China apps driven, while learning from international community • Will release V2.0 in June 2005 • Based on WS-I and uses a computer systems approach • Vega and OGSA • Partner with OGSA-UK • Use OMII as a kernel and system services • Naming (EVP), Grip, and Agora
