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