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)

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

CDF Resources Needs as IFC
Proportional Model: scale FY2005 resources
FY200x demand = (FY2005 resources)x(FY200x/FY2005)data vol.

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.

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!

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

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

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

CDF needs: disk space
CDF has some disk space assigned at CNAF.
We ask for a little more to do data analysis

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
