MPI_TOPO_TEST(3)MPI_TOPO_TEST(3)NAMEMPI_Topo_test - Determines the type of topology (if any) associated with
a communicator
SYNOPSIS
C:
#include <mpi.h>
int MPI_Topo_test ( comm, top_type )
MPI_Comm comm;
int *top_type;
C++:
#include <mpi.h>
int Comm::Get_topo()
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER comm, status, ierror,
CALL MPI_TOPO_TEST(comm, status, 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_Topo_test routine determines the type of topology (if any)
associated with a communicator. This routine accepts the following
parameters:
comm Specifies the communicator (handle)
top_type Returns the topology type of communicator comm (choice)
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
