Presentation Transcript

  1. Ian Bird, CERN Rob Gardner, University of Chicago Grid Middleware & TOOLS session summary

  2. Introduction • 82 abstracts submitted, • 36 oral presentations (7 sessions), 44 posters, [2 withdrawn] • Categories: cover a broad range • Experiment experiences • Data Management • Workload Management • Monitoring, Information, Accounting • Security & Authorization • Fabric & Deployment

  3. Experiment experiences

  4. Grid reliability – Pablo Saiz

  5. Grid efficiency during CMS data challenges – Oliver Gutsche

  6. D0 – reprocessing on OSG Amber Boehnlein Common theme: making sites reliable requires debugging sites/systems one by one

  7. Job agents – pilot jobs Monitoring Alien grid environment - Pablo Saiz

  8. Data management

  9. SRM v2.2 – Flavia Donno 18 month effort to agree, build, test, deploy new version

  10. dCache – one of several MSS systems • Patrick Fuhrmann – overview of dCache developments • - Gerd Behrmann – distributed instance for NDGF

  11. LCG Data management tools LFC, DPM, FTS – Markus Schulz

  12. Examples of services that consider deployment & management issues

  13. CORAL – distributed database access Dirk Duellmann

  14. Workload management

  15. Pilot jobs?

  16. Pilot jobs – and variants: Such a good idea – everyone wants one …

  17. Stuart Paterson – optimizations in DIRAC Marianne Bargiotti Integrity checking in DIRAC

  18. Pilots can move intelligence into the jobPaul Nilsson – Panda experience

  19. gLite WMS developments Marco Cecchi

  20. Igor Sfiligoi – comparison of WMS CHEP'07, Victoria

  21. Monitoring, information, etc.

  22. Experiment dashboards Julia Andreeva Monitoring from VO/user perspective

  23. GridICE – monitoring Guido Cuscela Permits different views of running jobs

  24. James Casey Advances in monitoring of grid services

  25. Stephen Burke – 6 years experience with GLUE schema Martin Flechl – details on integration of information systems

  26. Security, authorization, etc

  27. David Groep - glExec Supporting pilot jobs

  28. Fabric & Deployment

  29. Greig Cowan Using DPM over the WAN

  30. Addressing failover for core operations services – Alfredo Pagano Various strategies

  31. Platform LSF – Robert Stober Integrating heterogeneous clusters

  32. Observations • Solutions exist for most needs now – • Certainly not all perfect yet • Experiment layer relatively deep • Plethora of workload management systems • Not so many for data management … • Service management issues starting to be addressed by some services (DPM, LFC, FTS, Gridsite, Coral) • But in general little thought on how site managers should manage services • Interoperability / interoperation

  33. Observations • Workload management • Everyone wants pilot (aka glidein) jobs (and everyone has written a system to submit them) • Commonality – to reach a reliable service experiments need to systematically debug sites being used: • D0, CMS, dashboards, … • Sophisticated systems to monitor, debug, recover • Dirac, dashboards, grid service monitoring, etc., • To improve reliability and help debug the system
