---+ Cosmic Simulation in rel 14: *Samples* %TOC{title="Contents:"}% ---+ Overview * These samples are produced in 14.4.0 AtlasProduction on the batch system, although simulation step is also available with Simulation/SimuJobTransforms/scripts/csc_cosmics_sim_trf.py * What we used for these samples is now included in SimuJobTransforms-00-07-99, which needs tags G4CosmicFilter-00-00-12 and CosmicGenerator-00-00-34. <!--- Tags for simulation: G4AtlasApps-00-02-87, CosmicGenerator-00-00-31, InDetSimEvent-00-04-09, G4CosmicFilter-00-00-10, SimuJobTransforms-00-07-86 (and some later updates, see next bullet) --> * *The new simulation transform is included in 14.5.1.2,AtlasProduction,runtime*. Run without arguments for instructions - here is an example anyway: <verbatim> csc_cosmics_sim_trf.py outputHitsFile=sim.root maxEvents=10000 randomSeed=1234 geometryVersion=ATLAS-GEONF-04-00-00 CosmicFilterVolume=TRT_Barrel CosmicFilterVolume2=Pixel conditionsTag=OFLCOND-CSC-01-00-00 jobConfig=Cosmics.py </verbatim> * Tags for digitization: CommissionUtils-00-00-21, PixelDigitization-00-07-13-02, SiDigitization-03-05-04, SCT_Digitization-00-11-13 . jobOptions testdig.py attached. * The size of the ATLAS-GEO samples will be ~50k events when first stage finished. * To access the data use STAGE_SVCCLASS=atlasgroupdisk * Two filters: CosmicGenerator constrains the production vertex and direction of generator-level tracks, G4CosmicFilter requires simulated hits inside a certain volume - more details on the settings for the generator can be found in the attached jobOptions_ConfigCosmicProd.py. * Some limitations: * Several questions lately: note that the mu+/mu- ratio in simulation (1.5) is not the same as in data. The simulation flux calculation uses this reference: A. Dar , Phys. Rev. Letters 51, 227 (1983) * Timing is wrong for the muons, trigger will not work. ---++ List of geometries used: * *ATLAS-GEO-03-00-00* (aligned, Solenoid On, Toroids On) * *ATLAS-GEONF-04-00-00* (aligned, no magn field) * *ATLAS-GEO-04-00-00* (aligned, Solenoid off, Toroids On) ---++ List of simulation filter volumes used: * *Muon* (all of Atlas, geant volume is MUONQ2::MUONQ2) * *TRT barrel* (geant volume is TRT::BarrelOuterSupport) * *Pixel barrel* (has to have hits inside geant volumes TRT::BarrelOuterSupport _and_ Pixel::Pixel) _Please note that all subsystems are switched on in all samples; the naming refers just to the filtering on the track direction_ ---+ Samples ---++ Production with Muon Volume ---+++++ ATLAS-GEO-03-00-00: * 5000 events at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEO-03-00-00/dig/dig.muon_B.70000x.root where x=1-5 ---+++++ ATLAS-GEONF-04-00-00: * so far only a few thousand test events. Pixel hit timing not correct for these. Can be found at ~gencomm/w0/cosmicSim_rel14/NoField/dig.muon*.root . ---++ Production with TRT barrel Volume ---+++++ ATLAS-GEO-03-00-00: * 58666 events at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEO-03-00-00/dig/dig.GEO-03-TRTBarrel.*.root * The corresponding hits files can be found in the ATLAS-GEO-03-00-00/sim directory ---+++++ ATLAS-GEONF-04-00-00: * 50327 events at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEONF-04-00-00/dig.trtbarrel.200*.root * The corresponding hits files can be found in the ATLAS-GEONF-04-00-00/hits directory ---+++++ ATLAS-GEO-04-00-00: * 57756 events at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEO-04-00-00/dig * corresponding hits files can be seen in ATLAS-GEO-04-00-00/sim directory ---++ Production with pixel barrel Volume ---+++++ ATLAS-GEO-03-00-00: * Approx 46k events can be found at: /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEO-03-00-00/dig/dig.pixelbarrel_B.400*.root * The corresponding hits files can be found in the ATLAS-GEO-03-00-00/sim directory ---+++++ ATLAS-GEONF-04-00-00: * Approx 48k events at /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEONF-04-00-00/dig.pixelbarrel.500*.root * The corresponding hits files can be found in the ATLAS-GEONF-04-00-00/hits directory ---+++++ ATLAS-GEO-04-00-00: * 55368 events. Files are in /castor/cern.ch/grid/atlas/atlasgroupdisk/proj-simcos/rel14/ATLAS-GEO-04-00-00/dig/dig.pixelbarrel_B.600*.root * The corresponding hits files can be found in the ATLAS-GEO-04-00-00/sim directory ---++ How to run reconstruction: * Use release 14.5.0.2,AtlasProduction * Check out and compile <verbatim>cmt co -r RecExCommission-00-03-94 Reconstruction/RecExample/RecExCommission</verbatim> * get JO: <verbatim> get_files -jo Collisions_ATN.py </verbatim> * edit this file with the following <verbatim> add the lines: jobproperties.Beam.beamType.set_Value_and_Lock('cosmics') rec.doTrigger.set_Value_and_Lock(False) after the importing of the flags. edit the lines: < globalflags.DetDescrVersion.set_Value_and_Lock('ATLAS-Comm-02-00-00') < athenaCommonFlags.PoolRDOInput.set_Value_and_Lock( ["/afs/cern.ch/atlas/maxidisk/d17/dig.trtbarrel_ma_B100.root"]) to point to the dataset you want and to set teh DetDescrVersion correctly for that datset. (you may also have to edit the lines: jobproperties.BField.solenoidOn=True jobproperties.BField.barrelToroidOn=True jobproperties.BField.endcapToroidOn=True to se the magnetic field configuration correctly). for simulation made in rel 14 remove the line: SpecialTileConfigHack=True edit the number of events you want to run over: athenaCommonFlags.EvtMax.set_Value_and_Lock(500) </verbatim> * then run like: <verbatim> athena -c RTTsim=True Collisions_ATN.py </verbatim> * This will run and produce ESD, CBNT. you can configure the job to also produce monitoring histograms, TAG_COMM, Jive xml by adding the appropriate rec flags. (monitoring histograms fail if the run number changes during the job - which happens with old (<14) simulated cosmics) ---++ useful info * we can see how full our castor diskpool is by looking: [[http://atladcops.cern.ch:8000/mappings/groupdisk.log][here]] our limit is 5TB -- Main.ElseLytken - 9 Dec 2008 * [[%ATTACHURL%/testdig.py.txt][testdig.py.txt]]: example of digitization jobOptions * [[%ATTACHURL%/jobOptions_ConfigCosmicProd.py.txt][jobOptions_ConfigCosmicProd.py.txt]]: Cosmic generator settings
