\page Examples_parallel Category "parallel"

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

• \ref Examples_MPI

  The directory contains a native interface with MPI libraries, as a Geant4 UI library, and a set 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.

• \ref ExampleThreadsafeScorers

This example demonstrates a very simple application where an energy deposit and # of steps is accounted in thread-local (i.e. one instance per thread) hits maps with underlying types of plain-old data (POD) and global (i.e. one instance) hits maps with underlying types of atomics.
