Geant4 - an Object-Oriented Toolkit for Simulation in HEP

TBB/B2b
|
|
--------
|
|
|
|
This example shows how to integrate Intel Threading Building Block and Geant4
|
|
to achieve event-level parallelism.
|
|
|
|
Note that this is a preliminary version which should not be considered a
|
|
feature-complete example and which presents some limitations (no merging of
|
|
output, no correct clean-up of heap). It will be substantially improved
|
|
in 2014.
|
|
|
|
This example adds to B2b example, originally provided in basic example,
|
|
the TBB based classes:
|
|
|
|
tbbMasterRunManager:
|
|
--------------------
|
|
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.
|
|
|
|
tbbWorkerRunManager
|
|
--------------------
|
|
This class implements the worker model run manager for TBB based
|
|
application.
|
|
It is instantiated by tbbUserWorkerInitialization and used by
|
|
tbbMasterRunManager.
|
|
See G4WorkerRunManager for documentation of methods relative to
|
|
base class. Only class specific methods are documented here.
|
|
|
|
tbbUserWorkerInitialization
|
|
---------------------------
|
|
This class implements TBB specific worker initialization.
|
|
It is a sub-class of G4UserWorkerThreadInitialization.
|
|
Its role is to instantiate a tbbWorkerRunManager to be used by
|
|
tbb tasks.
|
|
|
|
tbbTask
|
|
---------------------------
|
|
This class represents one TBB task.
