Detailed Description

Todo:

Move anything that's not geometry/materials to the celeritas lib

Function Documentation

disable_geant_signal_handler()

void celeritas::disable_geant_signal_handler ( )

inline

Clear Geant4's signal handlers that get installed on startup/activation.

This should be called before instantiating a run manager.

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!
