MPI_SEND(3)MPI_SEND(3)NAMEMPI_Send - Performs a basic send operation
SYNOPSIS
C:
#include <mpi.h>
int MPI_Send( buf, count, datatype, dest,
tag, comm )
void *buf;
int count, dest, tag;
MPI_Datatype datatype;
MPI_Comm comm;
C++:
#include <mpi.h>
void Comm::Send(
const void* buf,
int count,
const Datatype& datatype,
int dest,
int tag) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
<type> BUF(*)
INTEGER count, datatype, dest, tag, comm, ierror
CALL MPI_SEND(buf, count, datatype, dest, tag, comm, ierror)
STANDARDS
This release implements the MPI 1.2 standard, as documented by the MPI
Forum in the spring 1997 release of MPI: A Message Passing Interface
Standard.
DESCRIPTION
The MPI_Send routine performs a basic send operation. This routine
accepts the following parameters:
buf Specifies the initial address of the send buffer (choice)
count Specifies the number of elements in the send buffer
(nonnegative integer)

MPI_SEND(3)MPI_SEND(3)
datatype Specifies the data type of each send buffer element (handle)
dest Specifies the rank of the destination (integer)
tag Specifies the message tag (integer)
comm Specifies the communicator (handle)
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
file.
NOTES
This routine may block until the message is received.
All MPI routines in Fortran (except for MPI_Wtime(3) and MPI_Wtick(3) )
have an additional ierr argument at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine
in C. In Fortran, MPI routines are subroutines and are invoked with the
CALL statement. Additionally, in Fortran, all MPI objects (for example,
MPI_Datatype and MPI_Comm) are of type integer.
