Offloading to GPU using G4VTrackingManager
Testbed application for offloading from Geant4 to AdePT/Celeritas via
concrete G4VTrackingManagers.
- Understand commonalities/differences between how problem data is setup
- What setup/offload options are common
- Future common testing problems (easy switching between impls)
It's essentially (intended to be) a merge/blend of Celeritas' accel
examples and AdePT's Example22. At present only a trivial setup is
used.
Build/Use
The project uses CMake's FetchContent to pull in AdePT's master
branch and Celeritas' v0.4.1 tag. The build should then work with
either AdePT's LCG view or a Celeritas Spack view (if not, then relevant
patches here or to the upstreams should be submitted).
The only program is the trackingmanager-offload, so just run this to
test at the moment. Comments in trackingmanager-offload.cc should illustrate
what's going on (and provide a basis for Doxygen going forward).
