MPI_WAITSOME(3)MPI_WAITSOME(3)NAMEMPI_Waitsome - Waits for specified communications to complete
SYNOPSIS
C:
#include <mpi.h>
int MPI_Waitsome( incount, array_of_requests, outcount,
array_of_indices, array_of_statuses )
int incount, *outcount, array_of_indices[];
MPI_Request array_of_requests[];
MPI_Status array_of_statuses[];
C++:
#include <mpi.h>
static int Request::Waitsome(
int incount,
Request array_of_requests[],
int array_of_indices[])
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER incount, array_of_requests(*), outcount,
array_of_indices(*), array_of_statuses(MPI_STATUS_SIZE,*),
ierror
CALL MPI_WAITSOME(incount, array_of_requests(*), outcount, array_of_indices(*), array_of_statuses(MPI_STATUS_SIZE,*), 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_Waitsome routine waits for specified communications to complete.
This routine accepts the following parameters:
incount Specifies the length of array_of_requests (integer)
array_of_requests Specifies the array of requests (array of handles)
outcount Returns the number of completed requests (integer)

MPI_WAITSOME(3)MPI_WAITSOME(3)
array_of_indices Returns the array of indices of operations that
completed (array of integers)
array_of_statuses Returns the array of status objects for operations
that completed (array of status)
ierror Specifies the return code value for successful
completion, which is in MPI_SUCCESS. MPI_SUCCESS is
defined in the mpif.h file.
NOTES
For C, the array of indices are in the range 0 to incount-1. For
Fortran, the array of indices are in the range 1 to incount.
