Detailed Description

Author

Tamas Banyai This header serves the necessary routines to interface C/C++ datatypes to MPI types. It is basically a reduced version of boost.mpi. Use the function get_mpi_datatype to acces MPI_type; New plain old data types are automatically registered. Non built-in types with smaller sizes result to lower performance due to memcpy. Never-ever use Datatype outside of namespace cf3:common::Comm. If you really need to use it, than rather extend the interface.
