RECO Status Report - August, 2002

Status of releases:

• p11.11.00 - Being installed on farms

  New features:

  • Enable offline threshold cuts for calorimeter and set to 2.5 sigma
  • Fix calorimeter non-linear corrections (problem introduced in p11.10.00)
  • Implement TMB+ (TMB + CalDataChunk + MuoTrackChunk)
  • Fix bug in emreco resulting in incorrect HMatrix chisq
  • Fix bug in SMT Lorentz corrections for Monte Carlo (long standing problem)
  • Add support for all existing tracking algorithms and provide tools for TRAC studies for p13
  • Add support for SMT / CFT calibration db access (use format = "data_db")
  • Bug fixes to deal with reported floating point exceptions

• p12 - Under development
  • p12.02.00 being built.
  • Not yet certified

• test release - As of t02.31.00
  • RECO
    • Segmentation violation in caldata (frequent) - potential fix scheduled for t02.32.00
    • Floating point exception in muonid when processing MC (common) - under investigation
    • Significant reduction in memory required do to rewrite of SMT maps (silicon_geometry - t02.30.00)
  • RECO_ANALYZE - runs
    • Include smt_lpos_ref - t02.30.00
    • Remove SmtPos*CollectChunks from RECO veto list - t02.30.00
  • DST / TMB
    • DST size - 260 KB
    • TMB+ size - 39 KB
  • Current outstanding problems / issues
    • DST size greater than 150KB
      • Four GTrack chunks currently in DST, reduce to 401 chunk only - t02.30.00
      • SMTMcIdDataChunk large, even when processing data - under investigation
    • d0om packing thumbnail errors
      • Some understood, fixed in t02.03.00
      • others under investigation
    • semreco has duplicate symbols - fixed in t02.30.00
    • elastic_reco broken - fixed in t02.31.00
    • Inefficient use of edm required unnecessary accesses to chunks
      • edm::findAll - avoid dereferencing chunks that are not of the proper type - fix available from Scott available for t02.30.00
      • Use d0_Ref in SmtDataChunk - fix available from Scott for t02.30.00
    • A lot of noise print in .out file - fixed (for now)
      • muo_caltrackreco - fixed in t02.30.00
      • hmreco - fixed in t02.30.00
      • bc_nnTagreco - fixed in t02.30.00
      • l1l2collector - fixed in t02.30.00
    • No primary vertices found - wrong rcp parameter - fixed in t02.30.00

Recent progress:

• Offline calorimeter thresholds have been implemented.
• TMB+ is available.
• analysis_example is being made available.
• Testing of RECO in test releases has resumed.

Major outstanding problems:

• Without access to the calibration databases, official running of RECO requires SMT and CFT flat files, which are available in the head versions of CVS packages. Non-farm users have been unaware of this requirement. Currently under consideration: improve documentation, automate access with d0tools.
• RECO_ANALYZE crashes on Monte Carlo farms in p11, due to what appears to be a reoccuring bug related to connections to the network. Under investigation

Ongoing projects:

• Tracking algorithms for p13 - A committee was recently appointed to collect data concerning the currently available tracking algorithms and make recommendations concerning which algorithms should be run in p13. All combinations of algorithms that will be tested have been made available in p11.11.00.
• RECO Monitoring tasks - Currently eight people have volunteered and are working on the two advertised RECO monitoring projects.
• Chunk documentation - Currently two people have volunteered.
