  1. CDF Status of Computing Donatella Lucchesi INFN and University of Padova Donatella Lucchesi

  2. Introduction • Status and Plans for data and Monte Carlo production @FNAL • Status and Plan Monte Carlo production @CNAF/EU • Data outside FNAL • CDF-Italy needs • Remote shift control room (Fabrizio Scuri) Donatella Lucchesi

  3. Data Production Status • Offline reconstruction algorithms frozen in fall 06 • Data reconstruction performed for 1 fb-1 • Post shutdown: • Dataset cut-off: Sep 01 ~ 200 pb-1 • Start producing new data Oct 01 • Done by end of November • Calibration process will be improved for the next step User level: • Many analysis use st-ntuples produced by the production Farm (not standard yet for B physics) • Diskpool in use for user (st-)ntuple, not production yet • (st-)ntuples stored also at CNAF Donatella Lucchesi

  4. CDF Resources Needsas IFC Proportional Model: scale FY2005 resources FY200x demand = (FY2005 resources)x(FY200x/FY2005)data vol. Input parameters: Results: Donatella Lucchesi

  5. Where CDF can find new Resources • Working on strategies to improve resources utilization: • One-pass production • Centralized ntuple production • Run dependent Monte Carlo production • Access GRID Resources • Merge several GlideCAF into one:NAmCAF • Born as Fermilab-San Diego CMS group project • Now include: FermiGrid, San Diego, MIT, Florida • lcgcaf: • CAF reimplementation to access LCG middleware • use gLite resource broker • CDF-Italy and INFNGrid project developed by: • F. Delli Paoli, D. Jeans, S. Sarkar, I. Sfiligoi and D.L. Donatella Lucchesi

  6. NamCAF It start being used Donatella Lucchesi

  7. Resources available to LcgCAF Italy: INFN-GRID: 2MspecInt2K, extra CNAF ~700KspecInt2K Already included: Barcelona, Lyon, Glasgow, Karlsruhe will be presented Joint Physics meeting and very soon in production! Donatella Lucchesi

  8. Need to be developed for CDF in GRID Monte Carlo Production Plans cdf-UI job job EU GRID LcgCAF output data GRID Storage Element cdf-cnaf-1 output data output data … validation storage area Buffer area Robotic Tape Storage SAM station Donatella Lucchesi

  9. LcgCAF Characteristic & Performances • CDF code distribution: AFS was a limitation, now • Parrot access to all sites • GRID failures due: sites misconfiguration, • temporary authentication problems and services • overloading in Resource Broker • Use GRID retry and the CDF internal resubmission mechanism Donatella Lucchesi

  10. Data analysis @CNAF • An automatic (almost) procedure to store at CNAF: • B data in any form: BCHARM dataset and/or • skimmed datasets and/or Bs-ntuple • st-ntuples (any format) for high-pt analysis • Provide users running on data at CNAF with standard CAF (icaf) area, access via CAF tools and rootd • Keep use GlideCAF until LcgCAF has same performances • Use LcgCAF to access data: • SAM-SRM interface development @FNAL. First deployment @CNAF: SRM installation (F. Delli Paoli) • Test of native GPFS (D. Jeans) • Lot of effort now in understanding which SRM Donatella Lucchesi

  11. CDF share respect to other experiments Total cpu time since April `05 Total cpu time August 2006 Need to agree with Tier 1 and Tier2 a minimum guarantee for CDF when LHC will start Donatella Lucchesi

  12. CDF needs: disk space CDF has some disk space assigned at CNAF. We ask for a little more to do data analysis Physics needs Currently: 75 TB Donatella Lucchesi

  13. CDF needs: cpu’s CDF is not asking more than what already discussed and approved. Tier 1 seems happy! Donatella Lucchesi

  14. Manpower Fermilab: I. Sfiligoi + San Diego group: “CAF +GRID transition” Replaced by D. Benjamin + R. Borgatti K. Genser T. Kuhr: “Data Handling and SAM” G. Compostella: Jul.-Sept. 2006, “CAF +NAmCAF” Italy: D. Lucchesi (coordination, SAM in Italy, data import-export) F. Delli Paoli (LcgCAF resp., CDF code, SRM development) ends in September 06 D. Jeans(GlideCaf-disk-user interface) new job Oct. 06 S. Sarkar(GlideCAF, LcgCAF, SRM) July 06 L. Brigliadori(support CNAF management) end January 07 New Assegno di ricerca @CNAF (Bando 10 settembre) F. Scuri +D. Fabiani Remote CO shift (Pisa) Interest express by colleagues for MC production coord. Donatella Lucchesi

  15. BACKUP Donatella Lucchesi

  16. Lcgcaf design Developers: F. Delli Paoli, D. Jeans, S. Sarkar and I. Sfiligoi advices Donatella Lucchesi

  17. Need for Physics Center Disk space: - BCHARM dataset and skimmed data are on disk - size of these datasets is scaled using luminosity, logging rate and event size What we need for B Data Donatella Lucchesi
