TOTEM Web>WebLeftBar>CompOfflineSw>CompOfflineCMSSWMigration620to704 (2014-09-22, PiotrSarnicki) (raw view)

---+ Migration of CMSSW software from 6_2_0 version to 7_0_4

What needs to be done:
   * Some more testing
   * Fix Raw Data Reader
   * Migrate some modules omitted in previous migration
   * Add CMS UATree producer
Raw Data Reader was not migrated due to changes in data format and project of Micha&#322; &#379;muda.

---+ Changes in configurations - general
To run your configurations, which are not in repository,  you may need to make some changes:
<verbatim>
In src/Configuration/TotemCommon/python/mixNoPU_cfi.py
+ mix.mixObjects.mixSH.crossingFrames = cms.untracked.vstring('MuonCSCHits',
+ 'MuonDTHits',
+ 'MuonRPCHits',
+ 'TotemHitsT1',
+ 'TotemHitsT2Gem',
+ 'TotemHitsRP')

In src/Configuration/TotemCommon/python/g4SimHits_cfi.py
Under Physics = cms.PSet( ... 
+         ElectronStepLimit         = cms.bool(False),
+         ElectronRangeTest         = cms.bool(False),
+         PositronStepLimit         = cms.bool(False),
+         MinStepLimit              = cms.double(1.0),

Under StackingAction = cms.PSet( ...
+         RusRoGammaEnergyLimit  = cms.double(5.0), ## (MeV)
+         RusRoEcalGamma         = cms.double(0.3),
+         RusRoHcalGamma         = cms.double(0.3),
+         RusRoMuonIronGamma     = cms.double(0.3),
+         RusRoPreShowerGamma    = cms.double(0.3),
+         RusRoCastorGamma       = cms.double(0.3),
+         RusRoWorldGamma        = cms.double(0.3)

In src/Configuration/TotemCommon/python/g4SimHits_cfi.py
+     UseMeasuredGeometryRecord = cms.untracked.bool(True),
This is because TOTEM uses MeasuredGeometryRecord instead of IdealGeometryRecord.

In src/Configuration/TotemCommon/python/g4SimHits_cfi.py 
-         LeaveScatteredProtons = cms.bool(True),  ##Leave intact protons after scattering for further near beam transport
-         LeaveOnlyScatteredProtons = cms.bool(False)  ##Leave only intact protons and reject all the other particles
+         LeaveScatteredProtons = cms.untracked.bool(True),  ##Leave intact protons after scattering for further near beam transport
+         LeaveOnlyScatteredProtons = cms.untracked.bool(False)  ##Leave only intact protons and reject all the other particles
This change was done to be CMS compatibile.

In Configuration/TotemStandardSequences/python/prodT1T2Default_cfg.py 
- process.g4SimHits.Generator.LeaveScatteredProtons = cms.bool(False)
+ process.g4SimHits.Generator.LeaveScatteredProtons = cms.untracked.bool(False)
</verbatim>

---+ Changes in configurations - merged configs
To make configurations work together, you should do the following:
   * create a root file with generated events
   * make configs treat this file as input
   * exclude generators from chain (if present).

In the example we're going to use: 
   * prodT1T2pythiaMBbeta11energy450GeV_cfg.py (TOTEM part)
   * step1_MinBias_13TeV_cfi_py_GEN_SIM.py and step2_DIGI_L1_DIGI2RAW_HLT_RAW2DIGI_L1Reco_RECO.py (CMS part).
Note: All configs - both original and modified - can be found as attachments.

1. Create and store events.
Changes with respect to "step1" config, which serves as base configuration (copy the internals of step1 and apply the changes).
<verbatim>
Change process name so that cmsRun does not complain.
- process = cms.Process('SIM')
+ process = cms.Process('EVENTSPRODUCER')

Specify number of events to create
-     input = cms.untracked.int32(-1)
+     input = cms.untracked.int32(5)

Change output file name.
-     fileName = cms.untracked.string('file:MinbiasTest_GEN_SIM.root'),
+     fileName = cms.untracked.string('file:bare_events.root'),

- process.simulation_step = cms.Path(process.psim)
- process.genfiltersummary_step = cms.EndPath(process.genFilterSummary)
- process.endjob_step = cms.EndPath(process.endOfProcess)

Just generate and store events.
- process.schedule = cms.Schedule(process.genfiltersummary_step,process.simulation_step,process.endjob_step,process.RAWSIMoutput_step)
+ process.schedule = cms.Schedule(process.generation_step, process.RAWSIMoutput_step)
</verbatim>

2. Modify TOTEM config
<verbatim>
Read events from file
+ process.source = cms.Source("PoolSource",
+         fileNames = cms.untracked.vstring("file:bare_events.root")
+    )

Process all events from file
-   input = cms.untracked.int32(10)
+   input = cms.untracked.int32(-1)

Remove generator from module chain
-process.p1 = cms.Path(process.generator*process.SmearingGenerator*process.g4SimHits*process.mix*process.T1Digis*process.t1cluster*process.t1rechit*process.t1roads*process.t1tracks2*process.T2Digis*process.T2MCl*process.T2Hits*process.T2RoadPadFinder*process.T2TrackColl3*process.T2CC)

+process.p1 = cms.Path(process.SmearingGenerator*process.g4SimHits*process.mix*process.T1Digis*process.t1cluster*process.t1rechit*process.t1roads*process.t1tracks2*process.T2Digis*process.T2MCl*process.T2Hits*process.T2RoadPadFinder*process.T2TrackColl3*process.T2CC)
</verbatim>

2. Modify CMS step1 config
<verbatim>
-     input = cms.untracked.int32(50)
+    input = cms.untracked.int32(-1)

-  process.source = cms.Source("EmptySource")
+ process.source = cms.Source("PoolSource",
+ fileNames = cms.untracked.vstring("file:bare_events.root")
+ )

-    SelectEvents = cms.untracked.PSet(
-        SelectEvents = cms.vstring('generation_step')
-    )

- process.generation_step = cms.Path(process.pgen)

-  process.schedule = cms.Schedule(process.generation_step,process.genfiltersummary_step,process.simulation_step,process.endjob_step,process.RAWSIMoutput_step)
+ process.schedule = cms.Schedule(process.genfiltersummary_step,process.simulation_step,process.endjob_step,process.RAWSIMoutput_step)
</verbatim>

No changes are needed for the step2 config.
