Present: A. Sailer, A.Tolosa Delgado, M.Frank, S. Banerjee
1) Pending problems
1.1) DDDigi TBB code needs migration to new oneAPI TBB interfaces (Issue 901):
Clash between Intel oneapi TBB and classic TBB.
-- Wouter promised to look into.
1.2) Issue 918: Should be addressed by PR920. Waiting for feedback.
HepMC3 reader with Pythia8 Argantyr generator: status checker not implemented
1.3) Issue 921: EDM4hep output MCParticleCollection should be named MCParticle
1.4) Issue 940: Integration of external library (CRY) for cosmic ray generation in DDG4 simulation: on hold
1.5) Issue 970: Support for digitization in ddsim: on hold
1.6) Issue 977: problem with geant4 visualization: on hold
1.7) Issue 978: inputting runtime constants to hits: on hold
Is this still a DD4hep issue or more a framework issue?
Last question requires specialized hits, specialized G4 SD and a framework.
2) Closed issues and fixed problems
2.0) PR974: RICH detector example and Geant4OpticalTrackerAction: many thanks to Christopher Dilks for providing this elaborate example.
We were always missing an optical tracker like a RICH!
2.1) PR975: materialBudget app: Allow for asymmetric detectors: thanks to Wouter for the implementation.
2.2) PR976: geoConverter app: Allow to export of DD4hep geometries to pure ROOT geometries: thanks to Wouter for the implementation.
The difference to DD4hepo exports to ROOT is the omission of the DD4hep detector description enhancements like
sensitive detectors, readouts, segmentations etc.
2.3) PR979: Use explicit namespace in DDCond dictionary: thanks to Marco Clemencic.
Apparently cling uses any "using" statement in the dictionary generation files.
This can lead to namespace clashes.
2.4) PR980: Remove using declarations in root-cling dictionary files: Markus Frank
Propagate PR979 also to all other root-cling dictionary files to avoid interpreter clashes with the global namespace
2.5) PR982: Fix to ddsim --gun.distribution eta should set eta_min, eta_max correctly: thanks to Wouter Deconinck
3) Round table
