  • Optimize the Geant4VolumeManager. Instead of mapping the Geant4 pathes as vectors of pointers,

  • Relevant changes are in the files DDG4/Geant4GeometryInfo.h and src/Geant4VolumeManager.cpp.

  • HitTupleAction: change how the tree is written and filled, because that caused segfaults in LCG stack runs of dd4hep example tests.

• 2024-12-10 Markus Frank (PR#1367)

  • If memory is an issue, the Geant4 memory consumption can be reduced using the smartless option of
    G4LogicalVolume entities. This MR exposes this feature of Geant4 to dd4hep.
    Example fragment of the code:

      Volume vol = ....;
      // 2 is the Geant4 voxelization default. 0 means no voxelization,
      // values bigger than 2 will need more memory.
      int value =  0 .... 5; 
      vol.setSmartlessValue(value);
    

    Fixes #1361
    • An example (+test) is supplied as well:
      • ClientTests/compact/DriftChamber.xml
      • ClientTests/scripts/DriftChamber.py
        where the voxelization is reduced.

  Bug fix in CylindricalGridPhiZ:

  • In the cellId member method, one now refrains from reducing the phi parameter modulo 2pi when its IDdescriptor is signed.
  • When the offset is null, this means that the phi range is now [-pi,pi], instead of the previously [0,2pi] which is not appropriate for a signed quantity.

  Add implementation for signal handling.

  • The generic signal handler in DDCore may be used and specialized by applications as shon in the DDG4 package (see for details src/Geant4Kernel.h)
  • Use generic signal handler in DDG4 for controlled shutdown on CTRL-C.
  • Add test DDG4_SIGINT_handler in examples/DDG4
    to enable the signal handling use from python:

    geant4 = DDG4.Geant4(kernel, tracker='Geant4TrackerCombineAction')
    geant4.registerInterruptHandler() 
    

    Please note: The signal handler must be explicitly installed. DDG4 is a library framework and does not intervene in actions which users possibly want to handle themselves! This mechanism looks simple enough that it should not be annoying.

• 2024-07-05 Markus Frank (PR#1288)

  • As reported in this issue #1285 under certain circumstances the memory usage of DDG4 goes through the roof. This was traced back to the creation of excessive maps in the Geant4VolumeManager, if the number of sensitive pathes is very high like e.g. for straw detectors.
  • To solve the problem, geometry constructors may not declare any sensitive volumes. Hence the Geant4VolumeManager will not be populated. To still make Geant4 functioning, the sensitive volumes may be declared a posterior after conversion using regular expressions as implemented in the class Geant4RegexSensitivesConstruction. This class is only an example how such functionality may be achieved: other solutions are possible as well. This functionality can be switched at the level of each subdetector participating in the experiment setup.
  • To illustrate, an example detector BoxOfStraws was constructed with a flag in the xml description:

      <detector id="1" name="BoxOfStrawsDet" type="DD4hep_BoxOfStraws" readout="BoxOfStrawsHits" vis="VisibleGreen" region="StrawRegion" limits="BoxOfStrawsLimitSet">
        <box      x="1*m"    y="1*m" z="1000*mm"  limits="BoxOfStrawsLimitSet" vis="VisibleRed"/>
        <straw rmax="0.5*mm" y="1*m" thickness="0.1*mm" vis="VisibleBlue">
          <material name="Iron"/>
        </straw>
        <gas vis="VisibleGreen">
          <material name="Argon"/>
          <non_sensitive/>
        </gas>
        <position x="0*m"   y="0*m"   z="0*m"/>
        <rotation x="0"     y="0"     z="0"/>
      </detector>
  

  Change <non_sensitive/> to <sensitive/> and the different behavor of memory allocation when starting Geant4 can be observed.
  The corresponding Geant4 python script can be found here:

  <DD4hep>/examples/ClientTests/scripts/BoxOfStraws.py
  

  The memory consumption differs then as follows (depending on the thickness of the straws, which determine the number of sensitive pathes):

  With explicit sensitive volumes:   
  before Geant4VolumeManager:    Virtual: 903.3m   resident: 690.5m
  after Geant4VolumeManager:     Virtual: 1848.2m  resident: 1.6g   
  
  
  With Sensitives matching regex and not sensitive volumes declared:
  before Geant4VolumeManager:    Virtual: 903.3m   Resident: 690.6m 
  after Geant4VolumeManager:     Virtual: 903.3m   Resident: 690.6m 
  Simulating:                    Virtual: 903.5m   Resident: 692.6m 
  

  Hence this is a possibility to significantly reduce memory consumption for highly granular subdetectors.

  • By default do not keep hash string for detector checksum to minimize resource usage.
    As pointed out in Issue #1143 keeping the hash string of detector
    components is very often too resource/memory consuming. Hence keep the hashed strings only if requested
    e.g. for debugging purposes. By default the hash strings are not kept.
    This means the produces hash sums are NOT backwards compatible, because during the checksum creation the
    hash strings from sub-components were used. These are now consequently replaced by the corresponding hash codes.

• 2023-02-09 Markus Frank (PR#1058)
  The export of dd4hep::units is problematic in the presence of identical libraries from DD4hep in the LD_LIBRARY_PATH:

  • The ROOT auto-class loading tends to falsely load these libraries if constants from the dd4hep namespace are requested in python. This is clearly wrong: the original libraries may not be binary compatible. The

  • The export of the units using a helper class fixes this and ensures that the auto load mechanism is not automatically triggered. This is at least a formally correct solution until the auto load mechanism is better understood.

  • In the ROOT loader for DDDigi the TBranch::SetAutoDelete(true) was not set causing eventually double deletion and arbitrary crashes. Data read by DDDigi are put on the store and deleted by the application to allow subsequent reading for feeding other threads. If ROOT would take care of the deletion, multi-threaded processing is not possible.
