Please Join DD4hep developer's meeting via Zoom
Present: S. Banerjee, M. Frank, F. Gaede, T. Madlehner, A. Sailer, C. Vuosalo
1) Pending problems
1.1) Pending problems reported by Sang Hyun Ko:
- Cannot setup Birk's constant as material property.
- No analogy to G4PVParametrized. Unclear if a solution is possible.
1.2) Add GFlash parameterisation to DDG4 (issue #802)
1.3) PluginFactoryBase::make_return problem with longs (Issue 875)
1.4) ROOT issue: for G4 units the radiation/interaction length is wrong by a factor 10
-- For CMS this problem does not show up.
-- Should only enter AFTER simulation (Geant4 materials do not have the radiation length as input)
-- Need to address this issue early next year.
1.5) 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.
1.6) Issue 909: ddsim gets stuck infinitely on some events (reported by T. Madlehner).
Infinite loop due to particle decaying to itself. This also may be a generator problem.
1.7) Issue 913: XML parsing with non-standard linux-locale.
2) Closed issues and fixed problems
----
2.1) PR 910: Fix to plugin manager: Prevent crash at load time if LD_LIBRARY_PATH is not set.
2.2) PR 911: Add VariantParameters extension + plugin. General purpose parameter map which can be attached to detector elements.
2.3) PR 916, 915, 914: Fixes/improvements of ddsim by Andre. Feature to load multiple xml files.
