Detailed Description

Simple interface for G4VTrackingManager-based integration.

This singleton integrates both thread-local and global data with the user application. To use this class in your Geant4 application to offload tracks to Celeritas:

• Set up the Options before calling G4RunManager::Initialize: usually in main .
• Call Build and BuildForMaster from the corresponding G4UserActionInitialization::Build functions
• Call BeginOfRunAction and EndOfRunAction from the corresponding G4UserRunAction

The CELER_DISABLE environment variable, if set and non-empty, will disable offloading so that Celeritas will not be built nor kill tracks.

The method names correspond to methods in Geant4 User Actions and must be called from all threads, both worker and master.

Todo:

Provide default minimal action initialization classes for user

Build()

void celeritas::TrackingManagerIntegration::Build

(

)

Initialize during ActionInitialization on a worker thread or serial mode.

We guard against Build being called from BuildForMaster since we might add worker-specific code here.
