  4. Major Systems Overview Raw Data enstore (tape) ILP Project Desktops production servers dCache Monte Carlo servers diskpool Off-site farms EURGRID/ PACCAF/ namgrid KISTI/MIT/ GP/CMS cdfgrid (5500 slots)

  5. Data Handling ► Enstore tape system: 16 LTO3 drive, 26 LTO4 drives ○ Delivering typically 20TB per day, 50TB peak ► dCache, main disk cache, ~400TB, with tape backend ○ Delivering typically 50TB per day, 150TB peak ► overall very smooth operations last year! 50TB/day > < one year >

  6. Data Handling ► dCache major upgrade 300TB → ~800TB in May ○ smooth transition on this major project – great success! ○ appears to have relieved large backlogs - a significant difference! capacity upgrade < 14 months >

  7. Data Handling ► Planning needs ○ no new tape drives added last year ○ loads expected to be manageable (thanks to dCache upgrade) ○ new tape storage robot arrived in July, plenty of space ○ purged ~5% in unused datasets ► Tape generation migration ○ from LTO-4 (0.8TB) to T10K (5TB) ○ testing recently signed off ○ 6 T10K drives in FY11, 4 more in FY12 ○ start migrating raw data this year, the bulk of our 9PB in FY12, 13 < 14 months >

  8. CdfGrid ► 5500 slots ► Smooth operations! ► last maintenance replacements purchased in FY11, start decreasing in FY13 ► Loads: - heavy but manageable Jan-Jul 5K > 40K > < 1 year >

  9. NamGrid ► A portal to offsite farms running OSG, ~20% of CdfGrid ○ achieved regular access to GP and CMS farms! ○ last fall achieved solid integration of the KISTI site! ○ accessing SAM cache and CdfCode ○ regularly runs MC ► MIT site continues to be very reliable! ►moderate loads 1000 > < 1 year >

  10. Tier1 Farm at CNAF Eurogrid ► Italian colleages reorganized the CNAF and LCGCAF farms ○ glideinWMS VO Frontend GlideIn Factory CNAF head-node LCG

  11. Eurogrid ► the glidein layer prevents LCGCAF from swallowing jobs this makes a huge difference!! ► data transfer are also faster due to general network improvement ► A huge success! Users are voting for it! ► European CDF resources which were languishing are now used! 1.5K > < 3 months >

  12. Diskpool ► 325TB of “persistent” dCache assigned to physics groups ► mostly smooth operations ► Alexei Varganov, our diskpool expert, has left for a new job ► Physics groups have decided the diskpool is less critical now, and we can backup data and live with the greater uncertainty ►backup process is very tedious – thanks to production group for their persistence – it will be done soon! GB status top 63 85% backed up, progressing hdg 33 done, almost signed off ewk 31 down to 3 users bnt 26 almost done exo 17 done qcd 16 investigating A lot of work: ~2000 datasets!

  13. Code Management ► Last winter developed large file (2 to 8GB) support ○ contributes to improved tape access speed done and deployed! ► New major project: develop legacy code releases ○ incorporate accumulated patches ○ modernize all support packages ○ finally migrate to root version 5! ○ improve infrastructure first test release is out now, hope to be done this fall!

  14. Production Operations ► smooth operations over the year ►New data Production ○ 3 billion events, 450 TB ► Ntupling, 3 flavors, data and MC ○ 6 billion events data/MC, 300TB ► Monte Carlo operations ○ Generated 890M events, 150TB last year - continued strong demand! ► Reprocessing…

  15. Reprocessing ► About half of our data has non-optimal Si clustering, reduces tagging 5-10% (Periods 18-28 out of 38) ► Rerun production and ntupling to recover efficiency we met the Higgs group request for Mar 11 delivery of their data!! ► now only a tiny bit left to do…

  16. Two More Projects Two more projects targeted for B physics… ► BStntuple ○ re-ntuple all the B physics data streams ○ add covariance matrix for tracks - allows arbitrary vertexing choices at the ntuple level ○ enables many new analyses, is flexible for the future, and will replace several custom ntuples ► Generic B MC ○ generate, simulate, produce, ntuple bb Monte Carlo ○ has been a wanted for a long, now becoming more urgent ○ details and targeted dataset size are under design

  17. The Final Push planning to get the last data out to physics fast !! P37 prd BStn reprocessing P37 ntp P38 calib P38 prd P38 ntp Special low energy data! s-scan s-scan reprocessing diskpool upload Sep Oct Nov Dec

  18. In the Long Term ► FY12: cdfgrid, dCache, services continue as-is ► FY13: cdfgrid, dCache reduced by size of production needs ► Continue with full functionality, reduced capacity for 5y - farm and interactive CPU - access to all data - production and ntupling capability - full MC simulation, with all generators ► Continuing past 5y ○ concepts under discussion ○ how will LHC discoveries overlap Tevatron data? ○ will require funding and attracting experts

  19. The Bottom Line ► CDF Offline had another very successful year! ○ smooth operations, manageable loads ○ clearing off diskpool ○ preparing future releases ○ delivered reproduced data ► As we dive into the new era ○ finishing strong … and fast! ○ long term still requires work, resources Thanks for your IFC contribution, it is crucial!
