// G4UserWorkerInitialization

|
|
// Class description:
|
|
//
|
|
// This class is used for multi-threading.
|
|
// The object of this class can be set to G4MTRunManager, but not to
|
|
// G4RunManager. G4UserWorkerInitialization class has five virtual methods
|
|
// as the user hooks which are invoked at several occasions in the life
|
|
// cycle of each thread.
|
|
//
|
|
// - virtual void WorkerInitialize() const
|
|
// This method is called after the tread is created but before the
|
|
// G4WorkerRunManager is instantiated.
|
|
// - virtual void WorkerStart() const
|
|
// This method is called once at the beginning of simulation job when
|
|
// kernel classes and user action classes have already instantiated but
|
|
// geometry and physics have not been yet initialised. This situation is
|
|
// identical to the 'PreInit' state in the sequential mode.
|
|
// - virtual void WorkerRunStart() const
|
|
// This method is called before an event loop. Geometry and physics have
|
|
// already been set up for the thread. All threads are synchronised and
|
|
// ready to start the local event loop. This situation is identical to
|
|
// 'Idle' state in the sequential mode.
|
|
// - virtual void WorkerRunEnd() const
|
|
// This method is called for each thread when the local event loop is
|
|
// done, but before the synchronisation over threads.
|
|
// - virtual void WorkerStop() const
|
|
// This method is called once at the end of the simulation job.
|
|
//
|
|
// Note: this object should be instantiated only once and set to
|
|
// G4MTRunManager, while the five methods above are invoked for each
|
|
// worker thread. Thus, to store thread-local objects, use the
|
|
// G4ThreadLocal keyword.
