| 3 | When Geant4 4.0 sees empty event, it still calls userStackingAction. |
|---|
| 4 | |
|---|
| 5 | In the function: |
|---|
| 6 | G4StackManager::PopNextTrack(G4VTrajectory**newTrajectory) |
|---|
| 7 | |
|---|
| 8 | in Geant4 4.0, one has: |
|---|
| 9 | |
|---|
| 10 | 145 if(userStackingAction) userStackingAction->NewStage(); |
|---|
| 11 | 146 #ifdef G4VERBOSE |
|---|
| 12 | 147 if( verboseLevel > 0 ) G4cout << " " << GetNUrgentTrack() |
|---|
| 13 | 148 << " urgent tracks and " << GetNWaitingTrack() |
|---|
| 14 | 149 << " waiting tracks." << G4endl; |
|---|
| 15 | 150 #endif |
|---|
| 16 | 151 if( ( GetNUrgentTrack()==0 ) && ( GetNWaitingTrack()==0 ) ) return 0; |
|---|
| 17 | |
|---|
| 18 | It seems to me that the call, `return 0' (line 151), should occur before |
|---|
| 19 | the call to `NewStage()' (line 145). If there are no tracks to |
|---|
| 20 | be stacked (neither GetNUrgentTrack() nor GetNWaitingTrack()), |
|---|
| 21 | then there is no new stage. So, it's a mistake to call |
|---|
| 22 | userStackingAction->NewStage(). |
|---|
| 23 | |
|---|
| 24 | This affects my parallelization of Geant4, in which I need to purposely |
|---|
| 25 | create a trivial event on the master, and call |
|---|
| 26 | G4EventManager()::ProcessOneEvent() on it to initialize the event on the |
|---|
| 27 | master. I am doing this in order to copy the hits from the slave into |
|---|
| 28 | an event on the master. |
