SHMEM_ADDR_ACCESSIBLE(3) Open MPI SHMEM_ADDR_ACCESSIBLE(3)
NAME
shmem_addr_accessible - Indicates if an address is accessible via Open-
SHMEM operations from the specified remote PE.
SYNOPSIS
C or C++:
#include <mpp/shmem.h>
int shmem_addr_accessible(const void *addr, int pe);
Fortran:
INCLUDE "mpp/shmem.fh"
LOGICAL LOG, SHMEM_ADDR_ACCESSIBLE
INTEGER pe
LOG = SHMEM_ADDR_ACCESSIBLE(addr, pe)
DESCRIPTION
shmem_addr_accessible is a query function that indicates whether a lo-
cal address is accessible via SHMEM operations from the specified re-
mote PE.
This function verifies that the remote PE is accessible via SHMEM data
transfer functions from the local PE, and that the specified address is
in a symmetric data segment with respect to the remote PE.
RETURN VALUES
C: The return value is 1 if addr is a symmetric data object and acces-
sible via SHMEM operations from the specified remote PE; otherwise, it
is 0.
Fortran: The return value is .TRUE. if addr is a symmetric data object
and accessible via SHMEM operations from the specified remote PE; oth-
erwise, it is .FALSE..
