Function Documentation

get_geant_num_threads()

int celeritas::get_geant_num_threads ( G4RunManager const &  runman )

inline

Get the number of threads in a version-portable way.

G4RunManager::GetNumberOfThreads isn't virtual before Geant4 v10.7.0 so we need to explicitly dynamic cast to G4MTRunManager to get the number of threads.

In tasking mode, the result may be zero!
