This directory includes example applications to demonstrate the usage of different techniques for achieving event parallelism with Geant4.

MPI is a native interface with MPI libraries. The directory contains a Geant4 UI library and a couple of parallelized examples. Using this interface, users applications can be parllelized with different MPI compliant libraries, such as LAM/MPI, MPICH2, OpenMPI, and so on.
Examples TBB demonstrate how to interface a simple application with the Intel Threading Building Blocks library (TBB), and organise MT event-level parallelism as TBB tasks.
TopC examples are Geant4 examples adapted to be run together with the TOP-C communication layer application on either a cluster of systems or multi-processor machines. They are based on N02 and N04 examples, originally provided in novice examples (see more in Old Novice Examples)
