// Class description:
|

|
|
// This class implements the master model run manager for TBB bases
|
|
// application.
|
|
// It is instantiated by user main (or equivalent function) instead
|
|
// of G4[MT]RunManager. It controls the creation of tbb::tasks.
|
|
// See G4MTRunManager for documentation of methods relative to base
|
|
// class. Only class specific methods are documented here.
|
|
//
|
|
// Equivalent in traditional MT:
|
|
// G4MTRunManager
|
|
//
|
|
// History:
|
|
// Nov 4th, 2013 A. Dotti - First Implementation
