shmem_pe_accessible
===================
.. include_body
:ref:`shmem_pe_accessible` - Determines whether a processing element (PE) is
accessible via SHMEM data transfer operations.
SYNOPSIS
--------
C:
.. code-block:: c
#include <mpp/shmem.h>
int shmem_pe_accessible(int pe)
Fortran:
.. code-block:: fortran
INCLUDE "mpp/shmem.fh"
LOGICAL LOG, SHMEM_PE_ACCESSIBLE
INTEGER pe
LOG = SHMEM_PE_ACCESSIBLE(pe)
DESCRIPTION
-----------
:ref:`shmem_pe_accessible` returns a value that indicates whether the calling
PE is able to perform OpenSHMEM communication operations with the remote
PE.
RETURN VALUES
-------------
C/C++
The return value is 1 if the specified PE is a valid remote PE for
SHMEM functions; otherwise,it is 0.
