MPI_IRSEND(3)MPI_IRSEND(3)NAMEMPI_Irsend - Starts a nonblocking ready send
SYNOPSIS
C:
#include <mpi.h>
int MPI_Irsend( buf, count, datatype, dest,
tag, comm, request )
void *buf;
int count;
MPI_Datatype datatype;
int dest;
int tag;
MPI_Comm comm;
MPI_Request *request;
C++:
#include <mpi.h>
Request Comm::Irsend(
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, request, ierror
CALL MPI_IRSEND(buf, count, datatype, dest, tag, comm, request, 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_Irsend routine starts a nonblocking ready send operation. This
routine accepts the following parameters:
Page 1
MPI_IRSEND(3)MPI_IRSEND(3)
buf Specifies the initial address of the send buffer (choice)
count Specifies the number of elements in the send buffer (integer)
datatype Specifies the data type of each send buffer element (handle)
dest Specifies the rank of destination (integer)
tag Specifies the message tag (integer)
comm Specifies the communicator (handle)
request Returns the communication request (handle)
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
file.
