• Data Reconstruction • Computing Farm and Tape storage• MonteCarlo:

– Production for 2001-02 data– Upgrade for 2004-05 data

• Reprocessing of 2001-02 data• False dead wires problem• Short and long term Plans

• Integrated Luminosity in 2004-05; size of the reconstructed data

• Quality of the reconstruction vs run number (few plots from datarec)

• Datarec version (19-20-21-22) vs run number• Status of dst’s production

Monte Carlo production for 2001-02 data completed in 2004-05

Update of the Monte Carlo for 2004-05 data

• Effort to produce a Monte Carlo simulation for 2004/05 data

• Tasks:– New interaction region– Attenuation lengths vs endcap module numbers– Regeneration and nuclear interaction– EMC time resolution– generator– Trigger jitter– Additional generators– lsb insertion code– Energy scale calibration– DC tracking resolution– Correlated noise in DC for charged kaons

Monte Carlo Production for 2004-05 data

• Final goal :

– Simulation of a sample corresponding to 1.7 fb-1 (estimated by the end of 2005)

– 20 % all phys + 100% neu Kaon +100% Kpm +500% radiative +...

– Extrapolating from 2001/02 ->280 days on 100 B80 CPU

Production schedule would be driven by analysis needs.

Reprocessing of 2001-02 data

• Motivation

• more compact sample and with refined selection/reconstruction routines.

• Sample: 420 pb-1 of data • Estimate time: 8000 CPU days • Schedule:

– Depends on the offline activities

• Current situation: 30 Cpu with dst’s and reconstruction running (1.4pb-1/day)

• First Part: 40 pb-1. Expected to finish in one month from now

Problem of false dead wires

• Description of the problem• Affected : MC2001-02, data 2004• Needs to:

– Redo the correct list for 2001/02 and 2004– Re-reconstruct the MC for a sub-sample of 2001/02 data (30

pb-1)

• Time scale:– Correct list for 2001-02 data done (1 month/24CPU)– Correct list for 2004 data: to be done (estimate time 45

days for 650 pb-1) – MC re-reconstruction: to be done (estimate time 15 days

for 30 pb-1)

Offline resources and activities

Offline Plans

• Short term (before the end of the year):– Reprocessing 2001/02 – Re-reconstruction of MC 2001/02 (at least 30pb-1)– Correct list of dead wires for 2004– MC 2004/05

• Long term list (probably from next year):– Reprocessing 2004 data– …
