This sounds like a reasonable proposal to me; it should be possible to create a sane definition for windows on intercommunicators. The RMA interface has focused on intracommunicators, so it could require several additions to e.g. make it possible to query both local and remote groups from the window. I think the main argument against adding this would be the increased complexity in the standard and to implementations. Given that there is a workaround (flattening the communicator to make the window, and using post/start/complete/wait to restrict the set of communication peers in active target), we would need to motivate such a change.

I captured your proposal in a ticket, https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/412, so we remember to discuss this further in the RMA working group.

thank you. Will remaining subscribed to this list be sufficient to receive notice of updates or should I poll above issue every few weeks?
