  1. Title • Status of • JetMetAnalysis • version 2.01 • Pal Hidas • FNAL Batavia / RMKI Budapest

  2. Content • bug fixes • new features • known problems : ORCA leaks • plan

  3. Bug fixes • there were plenty of them • jet - genjet matching ( now 2 genjet : GENJET5, GENJET7 ) • jet - particle matching • missing blocks • etc. • forget version 2.00 • tests on larger sample is necessary

  4. New features • One more element of MET block in the ntuple • metCalo(0) : met from calo towers, uncorrected • metCalo(1) : met from jets + out-of-cone towers ( both corrected - type 2 correction ) • New packages for elementary ORCA tests • JetMetTest - simple repetition of JetMetAnalysis without our private code ( simple iterations through ORCA objects ) • JetMetTestA - more simple - genpart and simulation only • JetMetTestB - calorimetry only • JetmetSimpleTest - environment only for elementary C++ codes • point : ORCA leaks, not JetMetAnalysis

  5. ORCA leaks • Leaking pieces of code on Linux, orca_4_5_1 • RecItr<EcalPlusHcalTower> myTower(ev->recEvent()); while(myTower.next()) { ntower++; } ; • SimEvent :: vertex_container :: const_iterator ivertex; for (...) { nvertex++; } ; • the same for SimEvent :: track_container ... • the latter are coming from SimEvent :: stdVArray<T> • each leaks ~50-100 kB/event depending on data • job aborts after 500-2000 events depending on machine • needs investigation of package developers • reported on orca-developers list • http://home.fnal.gov/~sceno/jpg/ntuple_maker/tests/Ntuple_tests.html

  6. Plans • produce ~10 k events ( Yujun ) • redo tau correction plots • observe problems • fix bugs • release production version 2.02 • reproduce all ntuples for MET studies ( Yujun ) • later tracker, muon stuff ... if no leak :-(
