Geant4 extended examples - TBB
TBB directory shows how to integrate Intel Threading Building Block and Geant4 to achieve event-level parallelism.
TBB/B2b
Currently only a preliminary version of one example is provided: it replaces the Geant4 Version 10.0 event-loop parallelism based on pthreads with TBB task-based parallelism. It should not be considered a feature-complete example and it present some limitations (no merging of output, no correct clean-up of heap).
It will be substantially improved in the future. If you have interest in TBB please refer to Geant4 Multi-threading user-forum (reachable from Geant4 website) where updates on TBB will be communicated or contact example author at: adotti@slac.stanford.edu.
