27 // Class description:
28 //
29 // This class implements the master model run manager for TBB bases
30 // application.
31 // It is instantiated by user main (or equivalent function) instead
32 // of G4[MT]RunManager. It controls the creation of tbb::tasks.
33 // See G4MTRunManager for documentation of methods relative to base
34 // class. Only class specific methods are documented here.
35 //
36 // Equivalent in traditional MT:
37 // G4MTRunManager
38 //
39 // History:
40 // Nov 4th, 2013 A. Dotti - First Implementation
