Detailed Description

Traits to determine MPI_DATATYPE from a C++ datatype.

Author:

Hari Sundar, hsundar@gmail.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.

Definition in file dtypes.h.
