001 // 28 Aug. 2001, Elena Gerchtein.
002 // These take effect AFTER release 4.0.0
003
004 // ALL EXEC BUILD's AND TCL FILES THAT USE GENERATORS
005 // SHOULD BE MODIFIED WITH RESPECT TO THE FOLLOWING CHANGES IN
006 // generatorMods
007
008 //-->--> GENERATOR SEQUENCE <--<--\\
009
010 All generators and related modules are put into sequences:
011 HardScatGenSequence
012 DecayPackageSequence
013 MinBiasSequence
014 GenFilterSequence
015
016 Two modules are responsible for writing header banks to the event
017 and writing HEPG bank:
018
019 GenInputManager
020 GenOutputManager
021
022 Test executable build generatorMods/test/cdfGen.cc
023 is an example of the right order of generator modules and sequences.
024 Order is important.

066 //-->--> MODULE DESCRIPTION <--<--\\
067
068 1) Input module - GenInputManager - writes header bank;
069 this module should be enabled if generators are used.
070
071 2) HardScatGenerator inherits AbsGenModule ( generatorMods/AbsGenModule.hh );
072 AbsGenModule provides HEPEVT management and random stream management.
073 No generator is enabled by default.
074
075 multiple interactions are not possible since tauola
076 and EvtGen are separate modules. I need to do some CdfHepEvt
077 modifications to keep list of HEPEVT states and process it
078 correctly with all other modules. The "talk-tos" are kept
079 in GeneratorModule anyway.
080
081 3) DecayPackages - modify HEPEVT;
082 I used QQModule from generatorMods but I'm not sure if it has
083 the same options as qq menu in FrameMods/GeneratorModule
084
085
086 4) GenOutputManager - writes HEPG banks from HEPEVT;
087 It also checks that only one HardScatGenerator is enabled
088 and it is possible to check other forbidden combinations
089 of enabled modules ( WGRAD + Pythia are excluded with the first
090 check and that was the only dangerous pair so far )
091 If check does not pass framework stop is requested.
092
093 5) MinBiasGenerator - writes HEPG banks from HEPEVT;
094 No generators are enabled by default.
095
096 6) GenFilters - filter HEPG banks.

130 //-->--> CURRENT STATUS <--<--\\
131
132 1) cdfGen produces the same HEPG output as cdfSim in 3.18.0int7
133 for any combination of hard scatter generator, decay package,
134 generator filter and min bias generator.
135
136 2) generation of multiple interactions does not work yet
137 ( the same is right for 3.18.0int7 ).
138
139 3) EvtGen currently works as decay package only until "generator"
140 version is provided.
