For that there is no such "accepted definitions" in the literature.
MPI-3.0 is an exception. In the MPI one-sided chapter, it is defined
in detail what is presented Figures 11.2 and 11.3 on pages 439 and 440:
local window accesses, RMA accesses and synchronizations.

And the sentence page 410 lines 17-19 generalizes this for 
local and remote accesses to shared memory.

For me, this is strange.

The solution in ticket #456 does not has this differentiation
between "local" and "remote".

The proposed new wording in new Section 11.5.4A does 
not contain any "local" or "remote" wording.

The solution in #456 is based on:
