MPI Datatypes

MPI Datatypes. The data in a message to sent or received is described by a triple (address, count, datatype), where An MPI datatype is recursively defined as: predefined, corresponding to a data type from the language (e.g., MPI_INT, MPI_DOUBLE_PRECISION) a contiguous array of MPI datatypes
