  • 2024-08-25 Andre Sailer (PR#1317)

    • DDSim: regexSD fix infinite loop, but change the interface from assignment to dictionary entries. Have to ensure only a single entry of a detector is given to the RegexSD

  • 2024-08-15 Sanghyun Ko (PR#1315)

    • DDSim: prevent Geometry.regexSensitiveDetector from always throwing exception when called with argument.

  • 2024-08-13 Andre Sailer (PR#1312)

    • GitlabCI: drop Flake check, since we have that on github as well

  • 2024-08-12 Andre Sailer (PR#1310)

    • GitlabCI: Use an el9 container to build documentation for the webpage

  • 2024-08-12 Andre Sailer (PR#1309)

    • CLICSiD AClick tests: avoid running in parallel, tests might break

  • 2024-08-12 Andre Sailer (PR#1308)

    • Geant4RegexSensitivesConstruction: allow using regex that don't match the full volume path, reduce time by 40% or so
    • DDSim: add interface for Geant4RegexSensitivesConstruction to geometry construction

  • 2024-07-30 Leonhard Reichenbach (PR#1303)

    • Added a Geant4TVUserParticleHandler that can utilise an arbitrary tracking volume as introduced in #384

  • 2024-07-24 ybedfer (PR#1294)

    • Adding a "CylindricalGridPhiZ" segmentation class.
      • N.B.: the class has a "radius" data member, registered by the constructors.

  • 2024-07-22 Markus Frank (PR#1301)

    • See issue #1292 and PR #1293 , fix crash when action dictionary not hashable.

  • 2024-07-22 Andre Sailer (PR#1299)

    • CI: use alma9 stack for python lint check
    • CI: move key4hep stack to alma9

  • 2024-07-22 Sanghyun Ko (PR#1298)

    • Geant4Converter: Improve lookup speed of GeoHandler::i_collect by using std::set instead of std::find (issue #1291)

  • 2024-07-06 jmcarcell (PR#1290)

    • Add the missing header unistd.h in a file to find ::open and ::close
    • Fix a few warnings about unused variables or shadowing
    • Add .cache and compile_commands.json to .gitignore

  • 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:
      $ python examples/AlignDet/scripts/AlephTPC.py -batch -events 5 -alignments examples/AlignDet/compact/AlephTPC_alignment.xml

    • Don't use the deprecated PySys_SetArgv

  • 2024-06-26 Andre Sailer (PR#1284)

    • DDG4.inputHandling: do not simulate rejectPDG particles even if they are called stable by the generator file, fixes #1282

  • 2024-06-26 Andre Sailer (PR#1283)
