shmem_fence - Provides a separate ordering on the sequence of puts
issued by this PE to each destination PE.
C or C++:
#include <mpp/shmem.h>
void shmem_fence(void);
Fortran:
INCLUDE "mpp/shmem.fh"
CALL SHMEM_FENCE
The shmem_fence() routine provides an ordering on the put
operations issued by the calling PE prior to the call to shmem_fence()
relative to the put operations issued by the calling PE following the call
to shmem_fence(). It guarantees that all such prior put operations issued
to a particular destination PE are fully written to the symmetric memory
of that destination PE, before any such following put operations to that
same destination PE are written to the symmetric memory of that destination
PE. Note that the ordering is provided separately on the sequences of puts
from the calling PE to each distinct destination PE. The shmem_quiet() routine
should be used instead if ordering of puts is required when multiple destination
PEs are involved.
The shmem_quiet function should be called if ordering
of puts is desired when multiple remote PEs are involved.
