Description

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)

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..
