Detailed Description

template<typename CELL_TYPE>
class LibGeoDecomp::ParallelMPIIOWriter< CELL_TYPE >

Just like MPIIOWriter, this class will generate snapshots of the simulation for checkpoint/restart capabilities.

Use this class for parallel runs. Consider MPIIOInitializer for restarting from a snapshot.
