  • 2024-07-05 Markus Frank (PR#1289)

    • Add RegexSD example for illustration: See #1288

  • 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.

  • 2024-07-01 Markus Frank (PR#1287)

    • As noted by Ben, the global alignment does not work in the presence of assemblies.
      This PR together with root-project/root#15905 fixes this deficiency.
    • An example was added to convert a globally misaligned geometry to Geant4:

    • Add reading of HepMC3 run info and forwarding it to output files: fixes #1114. Reliably this will only work for HepMC3 >= 3.2.6.

  • 2023-07-18 Markus Frank (PR#1146)

    • 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.

    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.

      -- configure
      -- initialize
      -- pre-run
      -- post-run
      -- terminate
      o Added interface function to directly communicate with the G4UI using string commands at any time
      from python.
      o Extended Geant4Kernel functionality to allow client actions to subscribe to stages of the program
      and perform dedicated actions on:
      -- configure
      -- initialize
      -- terminate
      As an example please see DDG4/src/Geant4UIManager.cpp

    • Dropped issue #1004 after some tests and investigation:
      This issue cannot be resolved, because MC records may also be read without Geant4 and a physics list being initialized.
      Hence the event readers cannot implement such a feature if the event record does not support charge, but only the PDG code.
      Conclusion is to best update the charge of particles at the output stage using the PDG code or to implement an event action,
      which performs this actions right before the output stage.
