Presentation Transcript

  1. LNF, Jun 30 2004 Offline meeting • Requests for MC Production • Status of current data reconstruction: • Update of offline libraries • Data quality • Ks tag presentation

  2. Requests for MC Production • Request from charged kaon group: fK+K-. at scale 1:1 • 640 Mev (410 pb-1) • 240 M sec @375 ms/ev • 70 days @40 CPU (10 fibm’s) • Other requests? • Relative priority of new MC production and reprocessing ? • Reminder: as today there is no way to estimate FILFO efficiency for • 2001/2002 data… • Already a request from ppg group to reprocess 2002 data’s • Still some work to do on MC: • Fix correspondence between CSPS elements and CELE (Miscetti) • New rp generator (angular distribution and FSR) (C. Bini - F. Nguyen)

  3. Update of ECL libraries: reading the boost from DB in ECLMOD In the new version of ECLMOD, the value of the boost is available (at Run Inizialization) from BPOS/BMOM bank

  4. Acquisition and reconstruction rate and volume Luminosity (mb/s) MB/nb-1 around June 22 EMC zero suppression changed to 2002 value (5sigma ->3 sigma) Kev/nb-1 Background

  5. Streaming data volume and CPU time (MB/nb-1) CPU (Kev/nb-1) A clear positive trend. We are close to our estimate for 2004 @ L=1032 cm-2 sec-1

  6. CPU TIME is function of Luminosity & Background RATE L(mb-1/s) 2004 estim. Estimate extrapolated from 2002 data CPU time (ms/evt) 2002 RM.B. (KHz)
