Preparazione al 5% data challenge (vedi
slides succ.)
Data challenge 5% (CMS IN/xxx)

5% Data challenge (dc04): Febbraio-aprile 2004

The 5% refers to a fraction of a final, 100% full Luminosity computing configuration. As described below,
that is about 25% of the complexity required for initial LHC running in 2007. The subsequent challenges will
take place in 2005 and 2006, and are scaled in turn to be 50% and 100% of LHC turn-on complexity. For
simplicity, we refer to these challenges henceforth as DC04, DC05 and DC06.

25 Hz * 3600 secondi * 20 ore * 1 mese = ~ 50 milioni eventi

Prerequisiti:
1. The Simulation phase must start approximately 7 months before the challenge, i.e. July 2003


a. OSCAR/GEANT4 must be fully validated by this time
b. 50kSI95 of CPU power must be available to CMS from this time for the remainder of 2003
c. The POOL persistency software must be sufficiently mature
2. Storage capacity in the range 150-200 TB (uncompressed) will be required. The Simulated data need not
reside at CERN, but the Digitized data will need to be available at CERN for the data-challenge proper.

a. The Simulated data (~100TB) will need to be kept, presumably at the main simulation sites or at
associated T1 centers. The media costs must be paid by somebody.

b. The Digitized data must be transferred to CERN and stored, at least for the duration of the data
challenge, plus say four-six months.

c. The transfer rate of digitized data to CERN must be of the order of 1TB/day for a continuous period of 2
months (Dec03-Jan04) from the ensemble of Tier centers. (Significant effort may be required here to ensure
transparent access for at least the critical servers.)
3. A model of dataset assignment and flow of data must be designed. With or without GRID tools being used in
this phase, the data flows must be optimized.
4. Initial LCG Global Grid Service (LCG-1) availability, at least for partial activities.
5. Integration of the CMS "Production Tools" into the Grid deployed environment.

2004-2005: Physics TDR




Periodo “caldo” 2004-2005, ma si comincia da subito a formare i
gruppi di lavoro…
Previsti due volumi:
Vol. 1) Detector response, reconstruction of physics objects,
calibrations, detector parameterization - maps current work (and
organization!) of the PRS groups
Vol. 2) High-level analyses, like Higgs, Supersymmetry, Exotic
physics, etc.- the new, additional work
CMS Week (23-27/9):
(Ri)organizzazione dei gruppi di fisica e di lavoro di CMS in vista
del Physics TDR: forse rinviata a dicembre…
