Mojo function

shmem_fence

def shmem_fence()

Ensures ordering of delivery of operations on symmetric data objects.

All operations on symmetric data objects issued to a particular PE on the given context prior to the call to shmem_fence are guaranteed to be delivered before any subsequent operations on symmetric data objects to the same PE on the same context. shmem_fence guarantees order of delivery, not completion. It does not guarantee order of delivery of nonblocking Get or values fetched by nonblocking AMO routines.
