are provided so that multiple \acp{PE} in a program can allocate symmetric,
remotely accessible memory blocks. These memory blocks can then be used with
\openshmem communication routines. When no action is performed, these
routines return without performing a barrier.
Otherwise, each of these routines includes at least one
call to a procedure that is semantically equivalent to \FUNC{shmem\_barrier\_all}:
\FUNC{shmem\_malloc} and \FUNC{shmem\_align} call a
barrier on exit; \FUNC{shmem\_free} calls a barrier on entry; and
\FUNC{shmem\_realloc} may call barriers on both entry and exit, depending on
whether an existing allocation is modified and whether new memory is allocated, respectively.
routines return without performing a \FUNC{shmem\_sync\_all} or
\FUNC{shmem\_barrier\_all} operation.
Otherwise, on exit, \FUNC{shmem\_malloc} and \FUNC{shmem\_align} includes at least
one call to a procedure that is semantically equivalent to
\FUNC{shmem\_sync\_all}. The \FUNC{shmem\_free} and \FUNC{shmem\_realloc}
calls a routine that is semantically equivalent to
\FUNC{shmem\_barrier\_all} both on entry and exit.
This ensures that all
\acp{PE} participate in the memory allocation, and that the memory on other
\acp{PE} can be used as soon as the local \ac{PE} returns.
