  1. EuroVO DCA WP5Coordination with Computational Grid Projects G. Taffoni – WP5 coord F. Pasian – INAF VO-DCA coord Giuliano Taffoni & Fabio Pasian - INAF

  2. What is WP5? • Interest area: massive and distributed computing, Grid computing • Promote coordination between computational Grid(s) and VObs • Point of view of Data Centres • GRID(s) through Data Centres Deliverables WP5-D12: Euro-VO – Computational Grids Workshop WP5-D13: Final Report on WP5 activities Giuliano Taffoni & Fabio Pasian - INAF

  3. …in practice • How can Data Centres benefit of GRID computing? • How can Astronomers benefit of Grid computing through Data Centres? • We give suggestions and more! Giuliano Taffoni & Fabio Pasian - INAF

  4. Where did we start? • Partners and collaborators • Kick off meeting (30 Nov – 1 Dec 2006) • Periodic teleconf Giuliano Taffoni & Fabio Pasian - INAF

  5. What we should do? …from Annex 1. • Gathering information on the different mechanisms for users to access the individual computational Grid infrastructures (middleware, authentication procedures, user interfaces, etc) through contacts with various computational Grid projects • How to interface Data Centre VObs computing tasks with the different computational Grids, through contacts with user communities (in coordination with WP4 and the TEG) and technical groups (e.g. VO-TECH) • Fostering access by Data Centre to own national Grids, through the organization of a dedicated workshop • Dissemination of the acquired knowledge • Verifying that requirements from the VObs community are taken in the appropriate consideration by the individual computational Grid projects, through contacts with computational Grid projects and the OGF. Giuliano Taffoni & Fabio Pasian - INAF

  6. 1. Knowledge Acquisition • Survey of European/National/Campus Grid initiatives • We currently see different flavors of Grids deployed • Because of application needs, legacy constraints, funding, etc • Diversity is essential to find best solutions • Grid computing standards are only being defined (OGF) • de jure and de facto standards • Do Astronomers that use the Grid exist? • YES: • National projects, No Astronomy-specific Grid project. • Give DCs a “link” to Grid projects and to Standards. Giuliano Taffoni & Fabio Pasian - INAF

  7. Authentication & Authorization Data Management Job Management Information system Single-sign-on VOSpace Workflows Information System (Registries) Core topics VObs Grids Giuliano Taffoni & Fabio Pasian - INAF

  8. 2. Coordination • Internal: • WP4, WP3 • External • GRID Project • OGF, EGEE, DEISA, National and Campus Grids • IVOA • Grid and WebSservices, AstroRG@OGF, Theory Interest Group • EuroVO-TECH • DS3 architecture, Theory Giuliano Taffoni & Fabio Pasian - INAF

  9. Theory • Theory is becoming important in the VObs • Inclusion of theory data in the IVObs • data already produced • data produced on the fly • Theory: • VO-DCA WP4, VO-TECH, IVOA • GRIDs Giuliano Taffoni & Fabio Pasian - INAF

  10. EuroVO DCA and Grids • EGEE: • We can (and do) use EGEE infrastructure • Interoperability • A new application specific environment for EGEE • What are the other Grid projects and what are their peculiarities? • ex: AstroGrid-D will use Globus, NOVA and Astro-Wise • How can we access also those resources? • INTEROPERABILITY is a keyword!!! Giuliano Taffoni & Fabio Pasian - INAF

  11. 3. Suggestions and guidelines • HOWTOs • best practice procedures to access Grid facilities from Data Centres • Suggestions (e.g.): • Similar/compatible auth&auth procedures ? • Data sharing between Data Centres and Grid ? • Interoperable workload management systems ? Giuliano Taffoni & Fabio Pasian - INAF

  12. 4. Dissemination • Pervasive knowledge of Grid systems to Data Centres: • HOWTOs • Single knowledge repository: up-to-date pointers to documents on Grid Initiatives • Workshop • Schools (in coordination with Grid projects) • Collections of Data Centres requirements • Make Grid initiatives aware of the VObs requirements • Interoperating is a two way interaction!!! Giuliano Taffoni & Fabio Pasian - INAF

  13. First year checkpoint …everything is related Giuliano Taffoni & Fabio Pasian - INAF

  14. 1. Knowledge Acquisition • Survey of EU grid initiative is a living document, available at the DCA wiki page • Grid standards on Authentication and Authorization, Data Management and Job Management • Correlated with the IVOA standards Giuliano Taffoni & Fabio Pasian - INAF

  15. Methodology • Documents are not enough…. • We identify some Data Centres that want to use Grid • We identify two use cases: • data oriented • theory oriented • Experiences drive our work. Giuliano Taffoni & Fabio Pasian - INAF

  16. DCA requirements on SSO EuroVO-TECH DS3 + IVOA GWS Delegation Service GSI+X509+PMA standard Prototype available VOMS plug-in Document on SSO Standards, (PMA, GSI, VOMS) Recommendations Suggestions. Single-sign-on Guideline Single-sign-on Giuliano Taffoni & Fabio Pasian - INAF

  17. 2. Interaction/Interoperability • New VOrg in EGEE: “dca.eurovo.org” • Data Centres and EGEE sites • EGEE-III “Astro” cluster • Participation to Grid conferences and forums (in particular OGF, EGEE) • OGF Interoperability Group (work in progress in coordination with IVOA) Giuliano Taffoni & Fabio Pasian - INAF

  18. 3. Coordination • Coordination with WP4 (back2back workshop) • Coordination with VO-TECH DS3 architecture • Coordination with IVOA Grid&WS group • Coordination with NA3 EGEE for training • Coordination between National VObs projects and Grid projects Giuliano Taffoni & Fabio Pasian - INAF

  19. NOVA example Giuliano Taffoni & Fabio Pasian - INAF

  20. 4. Dissemination • Wiki page for links and documents • EGEE NA4 and NA3 • Local and Campus Grids • Point Data Centres to workshops and training events organized by Grid projects Giuliano Taffoni & Fabio Pasian - INAF

  21. Next Milestone: EuroVO Computational Grids Workshop • 9-11 April 2008 • back2back with WP4 • Aim: “lay the groundwork to build the bridge between the VObs and the standard Grid infrastructures making developers from the different fields meet and exchange experiences and solutions.” • http://www.si.inaf.it/eurovow2008 Giuliano Taffoni & Fabio Pasian - INAF
