2. Donatella Lucchesi2 Sep 6 2006 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)

3. Donatella Lucchesi3 Sep 6 2006 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

4. Donatella Lucchesi4 Sep 6 2006 CDF Resources Needs as IFC Proportional Model: scale FY2005 resources FY200x demand = (FY2005 resources)x(FY200x/FY2005)data vol. Input parameters: Results:

5. Donatella Lucchesi5 Sep 6 2006 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.

6. Donatella Lucchesi6 Sep 6 2006 NamCAF It start being used

7. Donatella Lucchesi7 Sep 6 2006 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!

9. Donatella Lucchesi9 Sep 6 2006 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 SamplesEvents on tape   with 1 Recovery B->D s  D s ->  1969964~92%~100% B->D s  D s ->K*K2471751~98%~100% B->D s  D s ->K s K1774336~92%~100%

10. Donatella Lucchesi10 Sep 6 2006 Data analysis @CNAF  An automatic (almost) procedure to store at CNAF: o B data in any form: BCHARM dataset and/or skimmed datasets and/or Bs-ntuple o 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

11. Donatella Lucchesi11 Sep 6 2006 CDF share respect to other experiments Total cpu time August 2006Total cpu time since April `05 Need to agree with Tier 1 and Tier2 a minimum guarantee for CDF when LHC will start

12. Donatella Lucchesi12 Sep 6 2006 CDF needs: disk space CDF has some disk space assigned at CNAF. We ask for a little more to do data analysis Currently: 75 TB Physics needs

13. Donatella Lucchesi13 Sep 6 2006 CDF needs: cpu’s CDF is not asking more than what already discussed and approved. Tier 1 seems happy!

17. Donatella Lucchesi17 Sep 6 2006 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
