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](https://github.com/aidasoft/dd4hep/pull/1287)) + - As noted by Ben, the global alignment does not work in the presence of assemblies. + This PR together with https://github.com/root-project/root/pull/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` + +* 2024-07-01 jmcarcell ([PR#1286](https://github.com/aidasoft/dd4hep/pull/1286)) + - Fix warnings related to unused variables and shadowing of already existing variables + - Don't use the deprecated `PySys_SetArgv` + +* 2024-06-26 Andre Sailer ([PR#1284](https://github.com/aidasoft/dd4hep/pull/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](https://github.com/aidasoft/dd4hep/pull/1283)) + - DDSim: Do not check for existence of files behind a URL like root://, fixes #1281 + +* 2024-06-24 jmcarcell ([PR#1280](https://github.com/aidasoft/dd4hep/pull/1280)) + - CMake: Allow finding version 1.0 (and newer) for podio + +* 2024-06-21 Markus Frank ([PR#1279](https://github.com/aidasoft/dd4hep/pull/1279)) + - The conquest against tainted variables in coverity + +* 2024-06-20 Markus Frank ([PR#1278](https://github.com/aidasoft/dd4hep/pull/1278)) + - Fight coverity tainted variables. + # v01-29 * 2024-06-06 Andre Sailer ([PR#1277](https://github.com/aidasoft/DD4hep/pull/1277))
