Just to follow up on Jeff's comments:
I'm a member of the MPI-3 RMA committee and we are working on improving
the current state of the RMA spec. Right now it's not possible to ask
for local completion of specific RMA operations. Part of the current
RMA proposal is an extension that would all
I personally find the entire MPI one-sided chapter to be incredibly confusing
and subject to arbitrary interpretation. I have consistently advised people to
not use it since the late '90s.
That being said, the MPI one-sided chapter is being overhauled in the MPI-3
forum; the standardization pr
But that is what surprises me. Indeed the scenario I described can be
implemented using two-sided communication, but it seems not to be possible
when using one sided communication.
Additionally the MPI 2.2. standard describes on page 356 the matching rules

Best,
