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

Donatella Lucchesi2 Sep Introduction  Status and Plans for data and Monte Carlo  Status and Plan Monte Carlo  Data outside FNAL  CDF-Italy needs  Remote shift control room (Fabrizio Scuri)

Donatella Lucchesi3 Sep 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 Lucchesi4 Sep CDF Resources Needs as IFC Proportional Model: scale FY2005 resources FY200x demand = (FY2005 resources)x(FY200x/FY2005)data vol. Input parameters: Results:

Donatella Lucchesi5 Sep 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 Lucchesi6 Sep NamCAF It start being used

Donatella Lucchesi7 Sep 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 Lucchesi9 Sep 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 ->  ~92%~100% B->D s  D s ->K*K ~98%~100% B->D s  D s ->K s K ~92%~100%

Donatella Lucchesi10 Sep Data  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 First SRM installation (F. Delli Paoli)  Test of native GPFS (D. Jeans)  Lot of effort now in understanding which SRM

Donatella Lucchesi11 Sep 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

Donatella Lucchesi12 Sep 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

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

Donatella Lucchesi17 Sep 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
