Andre Sailer (CERN), Markus Frank (CERN)

Please Join DD4hep developer's meeting via Zoom

Present: A. Sailer, M.Frank, S.Banerjee, T.Madlehner

 

1) Pending problems

----

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.
2) Issue 940: Integration of external library (CRY) for cosmic ray generation in DDG4 simulation: on hold
3) Issue 970: Support for digitization in ddsim: on hold
4) Issue 984: DD4hep output with MarlinDD4hep

6) Issue 1014: Issue using optical surfaces
                        ===> Related: Issue 1027 (Program never stops)

7) Issue 1034: DD4hep and Opticks (Sarah)

 

To be closed

----

5) Issue 988: Propagate cross section to the simulation (on hold)
                        ===> likely a EDM4hep problem, However, could be part of the run-records now.
                        Should this be fixed since edm4hep podio frames.
9) Issue 1036: MCParticles not showing up in ROOT output

10) Issue 1037: Should the momentum vector be added to the DDG4 MC contribution object of a Geant4Particle ?
                        ===> Question.

                        ===> Accepted will be added in the sensitive detectors.

 

2)    Closed issues and fixed problems
----

1) Issue 1035: Export of geometries to XML
                        ===> Only GDML is supported....to be closed.

2) PR 1049: Update CI stack (Andre)
3) PR 1045: Update DD4hep exported setup script: Fix path duplicates (Andre)

4) PR 1050: DDG4: Write run header to EDM4HEP output (Thomas)

5) PR 1048/Issue 1043: Add -Wno-psabi flag to compilation (Andre). Harmless, since we use consistent builds
6) PR 1046/Issue 1036: ParticleHandler: account for modified stepping actions, where tracking of a particle could be paused and later restarted.
                      Current MC handler led to inconsistent results. (Andre)

7) PR 1044/Issue 1037: Add track momentum to MC truth contribution for Calorimeter hits -- as agreed in last meeting (Markus)

8): PR 1042: DD4hepSimulation: fix issue when compactFile did not contain a slash (Andre)
9): PR 1041: Improve DDDigi I/O interface: add edm4hep output, use podio frames (Markus) 

 

3) Round table

----
  Markus:     NTR

  Andre:       New tag 1.24 for dd4hep when moving to ROOT 6.28-patches.
  Sunanda:  NTR. Will eventually release new sw stack, but no time frame yet fixed O(month).

  Thomas:    NTR
 

4) AOB

Next meeting:  09. February 2023
