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.
