4. -4- Torino, 14-16 Aprile 2003 from Objectivity to ROOT/IO GONE ROOT/IO Files files in single directory XOR

5. -5- Torino, 14-16 Aprile 2003 CMKIN Interface to Pythia/Herwig/Isajet Cfr. /afs/cern.ch/cms/cmsim/cmk002/examples/00README Will become and independent project (= expect changes) > cmkin cmk002 > cp –pr $CMK_EXAMPLES. > cd examples/make_ntpl_job > kine_make_ntpl_pyt.com Executable is created in $SCRATCH/kine_make_ntpl_pyt.exe Sample batch job in kine_make_ntpl_pyt.run

6. -6- Torino, 14-16 Aprile 2003 CMKIN: Action Cards for various processes (mostly with PYTHIA) on the production page: http://cmsdoc.cern.ch/cms/production/www/html/general/ Take bt_h300_ZZ2mu2ele_Id_238.txt and edit it (cfr. ~namapane/public/Tutorial/day2/cmkin/) Run! $SCRATCH/kine_make_ntpl_pyt.exe < bt_h300_ZZ2mu2ele_Id_238.txt

7. -7- Torino, 14-16 Aprile 2003 CMSIM http://cmsdoc.cern.ch/cmsim/cmsim.html Initialisation (cms131 – just released!) > cmsim cms131 Cards http://cmsdoc.cern.ch/cms/production/www/html/general/ Take STANDARD_125_Id_42.txt and edit!

8. -8- Torino, 14-16 Aprile 2003 Examples/ExProduction FZ signal FZ minbias SimHits minbias SimHits signal RecHits Ntuple writeHits.cpp writeAllDigis.cpp //all we need is to link the correct libraries Populating the DB

9. -9- Torino, 14-16 Aprile 2003 Examples/ExProduction BuildFile This is to write SimHits into a DB To produce Muon barrel, endcap and RPC hits To produce all Tracker hits This is to write SimHits into a DB To produce Muon barrel, endcap and RPC hits To produce all Tracker hits writeHits Reading of FZ files Magic in selecting SCRAM Groups

10. -10- Torino, 14-16 Aprile 2003 Examples/ExProduction.orcarc (cfr. ~namapane/public/Tutorial/day2/writeHits/) Environment variables setenv DETINPUT $CMS_PATH/oo/reconstruction/datafiles/cms131/cms131.rz MaxEvents = 100 FZInputFiles = /castor/cern.ch/user/s/stw/cmsim/cms130/h300eemm.fz OutputDataSet = /System/SimHits/h300eemm GoPersistent = 1 MaxEvents = 100 FZInputFiles = /castor/cern.ch/user/s/stw/cmsim/cms130/h300eemm.fz OutputDataSet = /System/SimHits/h300eemm GoPersistent = 1 Example FZ files in /castor/cern.ch/user/s/stw/cmsim/cms130 writeHits ORCA 7_2_x works with cmsim v130/v131 eval `scram runtime -csh`

11. -11- Torino, 14-16 Aprile 2003 Action (1) Create HIT-files with 100 signal events with these cards Create HIT-files with 500 minbias events (for pileup): /castor/cern.ch/user/s/stw/cmsim/cms130/minbias.fz Write in : OutputDataSet = /System/SimHits/minbias

12. -12- Torino, 14-16 Aprile 2003 High luminosity -> 20 minimum bias events in one bunch crossing Overlay crossings -5 to +3 200 min.bias for 1 signal event "recycle" min.bias events Digitization and Pileup

13. -13- Torino, 14-16 Aprile 2003 Examples/ExProduction BuildFile This is to write Digis/RecHits into a DB To produce Calorimetry digis To produce all Muon digis To produce Tracker digis This is to write Digis/RecHits into a DB To produce Calorimetry digis To produce all Muon digis To produce Tracker digis writeAllDigis Reading of SimHits

14. -14- Torino, 14-16 Aprile 2003 Examples/ExProduction.orcarc (cfr. ~namapane/public/Tutorial/day2/writeAllDigis/) No Environment variables in addition to eval `scram runtime –csh` InputCollections=/System/SimHits/h300eemm/h300eemm OutputDataSet = /System/Pileup2x1033/h300eemm PUGenerator:Collection = /System/SimHits/minbias/minbias PUGenerator:AverageEvents = 3.46 PUGenerator:MinBunch = -5 PUGenerator:MaxBunch = 3 PUGenerator:FirstEvent = -2 InputCollections=/System/SimHits/h300eemm/h300eemm OutputDataSet = /System/Pileup2x1033/h300eemm PUGenerator:Collection = /System/SimHits/minbias/minbias PUGenerator:AverageEvents = 3.46 PUGenerator:MinBunch = -5 PUGenerator:MaxBunch = 3 PUGenerator:FirstEvent = -2 WriteAllDigis Default is No Pileup

15. -15- Torino, 14-16 Aprile 2003.orcarc CaloRecHit:EcalBarrel = 1 CaloRecHit:EcalEndcap = 1 CaloRecHit:HcalBarrel = 1 CaloRecHit:Preshower = 1 Ecal:Barrel:noise = 0.03 Ecal:Barrel:threshold = 0.06 Ecal:Endcap:noise = 0.15 Ecal:Endcap:threshold = 0.30 Hcal:noise = 0.0006 Hcal:threshold = 0.300 Presh:noise = 0.000015 Presh:threshold = 0.000054 Calo:Preshower:MinBunch=-2 Calo:Preshower:MaxBunch=1 Muon:Barrel:MinBunch = 0 Muon:Barrel:MaxBunch = 0 EcalTrigPrim:Threshold = 0.3 HcalTrigPrim:Threshold = 0.3 GoPersistent = 1 CaloRecHit:EcalBarrel = 1 CaloRecHit:EcalEndcap = 1 CaloRecHit:HcalBarrel = 1 CaloRecHit:Preshower = 1 Ecal:Barrel:noise = 0.03 Ecal:Barrel:threshold = 0.06 Ecal:Endcap:noise = 0.15 Ecal:Endcap:threshold = 0.30 Hcal:noise = 0.0006 Hcal:threshold = 0.300 Presh:noise = 0.000015 Presh:threshold = 0.000054 Calo:Preshower:MinBunch=-2 Calo:Preshower:MaxBunch=1 Muon:Barrel:MinBunch = 0 Muon:Barrel:MaxBunch = 0 EcalTrigPrim:Threshold = 0.3 HcalTrigPrim:Threshold = 0.3 GoPersistent = 1 (continued)

16. -16- Torino, 14-16 Aprile 2003 Action (2) Fully digitize 10 events with these cards!

17. -17- Torino, 14-16 Aprile 2003 Reading DIGIs Warning! Groups for all objects written are needed in the BuildFile for a reading application Example – Examples/Statistics/ExDigiStatistics This is to read Digis/RecHits This is to read Digis/RecHits reading of digitized events ORCA 7.1.X

18. -18- Torino, 14-16 Aprile 2003 Action! Try Examples/Statistics/ExDigiStatistics! Write your own.orcarc file!!! Try Workspace to see how many pile-up events we have!

19. -19- Torino, 14-16 Aprile 2003 Winter Mode Main interest for production Decouples METADATA creation from EVENTDATA creation Three steps per dataset create an empty METADATA structure process event samples in parallel jobs are fully independent (no locks) crashed jobs can be simply re-started construct METADATA with COBRA tools after all jobs finished Examples/ExProduction/writeDigi_WinterMode*

20. -20- Torino, 14-16 Aprile 2003 Try out… Check scripts in ~namapane/public/Tutorial/day2/winter writeDigi_WinterMode.init Only once writeDigi_WinterMode.job Several times… writeDigi_WinterMode.finalize Once, in the DB directory

21. -21- Torino, 14-16 Aprile 2003 WinterMode - Init Usual digitization cards plus: Blue: shared by all WinterMode steps Red: specific for initialization Winter = 1 EVD:Default = OnDemand Events:EVDCreate = PreAllocate Collections:EVDCreate = PreAllocate InitDataSet = 1 Winter = 1 EVD:Default = OnDemand Events:EVDCreate = PreAllocate Collections:EVDCreate = PreAllocate InitDataSet = 1

22. -22- Torino, 14-16 Aprile 2003 WinterMode - Jobs Usual digitization cards plus: Blue: shared by all WinterMode steps Red: specific for jobs – use different run numbers! Winter = 1 EVD:Default = OnDemand Events:EVDCreate = PreAllocate Collections:EVDCreate = PreAllocate OutputRunNumber = 123 Winter = 1 EVD:Default = OnDemand Events:EVDCreate = PreAllocate Collections:EVDCreate = PreAllocate OutputRunNumber = 123

23. -23- Torino, 14-16 Aprile 2003 WinterMode – Finalize Runs special COBRA applications Blue: in loop over all jobs Red: Upates METADATA for all attached runs Example: e4726b2a4b2611d783fd0040f45cca94.runid cp XXX.runid.orcarc AttachRun OWNERNAME DATASETNAME FixColl OWNERNAME DATASETNAME cp XXX.runid.orcarc AttachRun OWNERNAME DATASETNAME FixColl OWNERNAME DATASETNAME CARF:ResumeRun=RUNS.META.PileupTk1024; h300eemmRuns; Run1 EVD0_Collections.h300eemm.PileupTk1034; Collections_e4726b2a4b2611d783fd0040f45cca94; LeafMetaCollection CARF:ResumeRun=RUNS.META.PileupTk1024; h300eemmRuns; Run1 EVD0_Collections.h300eemm.PileupTk1034; Collections_e4726b2a4b2611d783fd0040f45cca94; LeafMetaCollection

24. -24- Torino, 14-16 Aprile 2003 Caveats! data written with one (pre-)release is probably unreadable with the next (pre-)release data written with one compiler (gcc-2.95.2) is unreadable with any other (gcc-3.2) Most BuildFiles currently require changes
