Merged PRs

  •  

Pending Problems

  • ISSUE1199: Persist hepmc vertex status code into output
                          ==> Should we eliminate Geant4EventReaderHepMC
                          ==> Decision: Geant4EventReaderHepMC will be removed
  • ISSUE1285:  Memory Consumption of Sensitive Detectors
                          ==> Should be handled as illustrated in PR1288. Intrinsic problem of the Geant4VolumeManager;
  • ISSUE1296:  DetectorImp::endDocument() called twice for some geometries?
                          ==> Unsure if it is a problem wrongly configuring multiple xml inputs.
  • ISSUE1297:  Possible to dump all available readout elements?
                         ==> Possibly a copy of unsolved ISSUE580 from Valentin about enumerating all sensitive cells.
  • ISSUE1319: Problem with regexSensitiveDetector and volume IDs
                         ==> Interesting use case for reg-ex sensitive detectors
                                 having a VolumeMgr equivalent.
  • ISSUE1320:  Replacing a Handle<Segmentation> which contains a MultiSegmentation with the underlying Segmentation
                         ===> Unclear what he really means. Questions after re-reading, calls like:
    Handle<SomeSegmentation> seg = multisegmentation->subSegmentation(cellID);
or
Segmentation* seg = multisegmentation->subSegmentation(cellID);
  • ISSUE1335: Uniform random picking of points on detector surfaces for noise studies
                This problem is linked to #1297 and #580.
  • ISSUE1373:  Add GeneratorInfo to EDM4hepReader (Andre)
    PR1371:  Read edm4hep (Andre)
                          ==> Why not closed ?
  • ISSUE1392:  DD4hep installation fails if Intel compiler is used for compilation
                          ==> Should we support icc ?

  • PR1240:     Add multithreading support to ddsim
  • PR1304:     SurfaceManager: lazily construct surface maps on demand (Leonhard Reichenbach)
  • PR1314:     Cylinder segment surface (Armin Ilg)

        New Pending PRs:

  • PR1370:  Feature celeritas integration (Sakib Rahman/EIC)
  • PR1377:  Use canonical variables for the installation locations of libraries and binaries (Andriish)
