man MPI_Irecv (Fonctions bibliothèques) - Begins a nonblocking receive

NAME

MPI_Irecv - Begins a nonblocking receive

SYNOPSIS

#include "mpi.h"
int MPI_Irecv( void *buf, int count, MPI_Datatype datatype, int source, 
               int tag, MPI_Comm comm, MPI_Request *request )

INPUT PARAMETERS

buf
- initial address of receive buffer (choice)
count
- number of elements in receive buffer (integer)
datatype
- datatype of each receive buffer element (handle)
source
- rank of source (integer)
tag
- message tag (integer)
comm
- communicator (handle)

OUTPUT PARAMETER

request
- communication request (handle)

NOTES FOR FORTRAN

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr 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.

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