  1. Offline running plans M. Moulson, 31 March 2004 • Outline: • Organizational issues • MC status update • Reconstruction: things to do for restart • kpm streaming • FILFO

  2. Organizational issues Graziano Venanzoni is new offline co-convenor effective at end of ppg paper (est. mid-April) Simona Giovannella is technical understudy (non-active role but ready to help in solving problems)

  3. MC production status • Problems with radiative K decays • precision problems • ordering of secondaries in K0e3 decays • New generators: K0  p+p-p0g, K+  p+p0p0g • Problem in all_phys card (affects DBV-17) • Both f  rp (including direct) and f  3p (direct) enabled • rad04 production run twice • 1st production: e+e-  wp0, p0 not simulated unless w  p0g • All problems fixed • rad04 rerun • all_phys currently running

  4. Other MC issues • New machines • Same geanfi executable, in principle no problems • However, should be considered two different platforms • All new productions (rad04, all_phys): • 25000-25999 new machines only • 26000-26499 old machines only • Other runs by luck of the draw • Tape space • 36 TB of library reserved for MC, ~24 currently used • When can I delete DBV-17? • Can we delete pre-mcprod MC?

  5. Plans & priorities • all_phys, 260M evts (running) 13 days • all_scan (all_phys off peak LSF=1), ~60M evts 3 days • neu_kaon, 410M evts 21 days • eeg100 (e+e-g, Eg > 100 MeV), 32M evts 2 days • Clear that we will conflict with restart of data taking • Not a big problem, one possible solution: • Old machines: MC • New machines: Reconstruction • Lengthens MC production time

  6. 1 – 28000 1 – 28000 1 - 99999 //cdcn/calibration/ //cdrn/run_cond/ //cdgy/geometry/ cn CALI rn RUNC gy GEOM c1 CALI r1 RUNC //cdc1/calibration/ //cdr1/run_cond/ 28001 - 99999 28001 - 99999 HepDB database upgrade (P. de Simone) Validity range PathName DBindex, DBname RTPATH routine selects the correct DB (index & pathname) based on run number and DB name: OLD: RTPATH(DBindex, BankName, PathName) NEW: RTPATH(RunN, DBname, BankName, DBindex, PathName )

  7. HepDB database upgrade (P. de Simone) • 2 new DBs have been created : rtcal_1_v2.rz (c1) • rtrnc_1_v2.rz (r1) • Done: RTDB library routines updated (in development area) • Done: Utilities to write/read the DBs for DC updated • EmC: dbload, other objects (?) still need update (EmC group) • In progress: All other routines in offline library that call RTPATH need updating

  8. Reconstruction upgrades • DC wire sags in tracking code— AA, SdA, MM • Adjust thickness of DC wall (-75 mm) in RTDB • Particular attention to backwards compatibility with MC • Medium-term plan is to re-reconstruct a significant fraction of old data • Do NOT want to pick up above changes since this would require re-reconstructing MC as well • May also want to continue MC production for old data with new executable • Hard cut on run number in ATFMOD and DCDBINI for both data and MC?

  9. Luminosity-scaling background trigger • Implement 20 Hz of random triggers in TORTA card • Generate test file • Decide how to implement luminosity scaling: • selection: stream one lsb to file event every N VLABs (LABs?) • insertion: stream all lsb events w/ n = number of intervening VLABs; insert only events with n > N • Modify ECLMOD to write lsb files • Modify INSERT to use lsb files (if scaling on insertion) • Modify MCPROD to use lsb files instead of bgg files • Attention to issues of backwards compatibility MM

  10. Miscellaneous streaming issues • dE/dx and DCDEDX A/C module: — MM, VP • Include DCDEDX in datarec path before streaming • Include DEID bank in DSTs • Event classification and streaming: • kpm — VP, BS • eliminate old tagging algorithms • dE/dx based tag • ksl: eliminate KSTAG algorithm— MM • rad: downscaled sample with less stringent cuts — FA, CdD • clb: various bug fixes — TS, MA
