  1. Grid Interoperability ShootoutGridPP and NGS GridPP 19 Ambleside 29-31 Aug 2007

  2. Physics Built for physics UCs SL4 (SLC4) gLite SRM ssh Non-physics Built for non-p UCs Various OS Globus, Condor,… SRB GSISSH Differences

  3. Command line Supported by specialised groups Big data volumes No need for secrecy Portals & cmd line Supported by a single (loose) group Not so big data vol. Some confidential Differences

  4. Site UIs “User installable UI” OS dependent Portals Specialised portals Workflow Or use GSISSH OS independent The UI

  5. The CA MyProxy VOMS (sort of) BDII & GLUE schema Big VO, small VO Common stuff

  6. Opportunities

  7. “Need for capability computing” • GridPP has high priority for ops • Data catalogues, file transfers • Documentation

  8. Portal work • GSISSH • “Research of the month” • ETF (or ETF’s experience) • Documentation, Training • User group meeting

  9. How to make grids interoperate • Standards • Strong Expertise in UK(I) • Influence external projects (priorities)

  10. Externalities EGEE OMII UK/Europe EGI and suchlike Standards OGF W3C OASIS Specialised industry or academic stds (e.g. archives)

  11. Storage – SRM and SRB globus-url-copy gridftp SRM SRB

  12. Storage – SRM and SRB FTS gridftp SRM SRM SRB

  13. Storage – SRM and SRB? lcg-* info SRM SRM SRB

  14. Storage – SRM and SRB? Interfacing once again brought up This time an ASGC project Aiming for “a demo” at SC SRM SRM2.2 SRM SRB

  15. MPI • NGS providing MPI • Took some effort • NGS benefited from (and worked with) GridIreland • Select MPI jobs via globus-job-submit

  16. The ETF • “Engineering Task Force” • http://www.grids.ac.uk/ETF/ (out of date) • Evaluates middleware • E.g., SGE, DPM, Unicore, • DPM was recommended as a useful storage solution

  17. RB gLite RB You probably can’t read this (how to lie with statistics)

  18. EGI? Other National Grids The big(ger) picture GridPP NGS Astro Grid Grid Ireland OMII TG OSG LCG

  19. Another big(ger) picture gin-data gin-jobs gin-auth gin-info

  20. Recommendations Job subm. Job subm. Mgmt Mgmt Storage Storage Establish links when it makes sense – stronger in some areas than others

  21. Conclusions • Opportunities for collaboration • Build on common areas • Many individual areas • Strong expertise in UK in many fields • Sometimes there are differences for a reason
