Classes
class	par::Mpi_datatype< T >
	An abstract class used for communicating messages using user-defined datatypes. The user must implement the static member function "value()" that returns the MPI_Datatype corresponding to this user-defined datatype. More...
class	par::Mpi_datatype< std::complex< T > >
class	par::Mpi_datatype< bool >
	A template specialization of the abstract class Mpi_datatype. This can be used for communicating messages of type "bool". More...

Detailed Description

Traits to determine MPI_DATATYPE from a C++ datatype.

Author

Hari Sundar, hsund.nosp@m.ar@g.nosp@m.mail..nosp@m.com

Traits to determine MPI_DATATYPE from a C++ datatype. For non standard C++ datatypes (like classes), we will need to define additional classes. An example is given for the case of the std. complex variable. Additional classes can be added as required.

Value:

template <>  \
        class Mpi_datatype<CTYPE> \
        {  \
            public: \
            static MPI_Datatype value() {\
                          return MPITYPE;\
                        } \
