Performs a basic send

Synopsis

#include "mpi.h"
int MPI_Send( buf, count, datatype, dest, tag, comm )
void             *buf;
int              count, dest, tag;
MPI_Datatype     datatype;
MPI_Comm         comm;

Input Parameters

buf initial address of send buffer (choice)
count number of elements in send buffer (nonnegative integer)
datatype datatype of each send buffer element (handle)
dest rank of destination (integer)
tag message tag (integer)
comm communicator (handle)

Notes for Fortran

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) havean additional argument ierr at the end of the argument list. ierris an integer and has the same meaning as the return value of the routinein C. In Fortran, MPI routines are subroutines, and are invoked with thecall statement.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
