Comm_create is definitely a separate ticket.  :)

Hi Jim,

I've just read the MPI_COMM_CREATE text in MPI-3.0 and you are correct that the order of statements there is also not ideal.

I'm not certain of where the re-read threshold is - that'll be a Forum decision on the day, I guess. Moving a couple of sentences, without changing their content, doesn't seem like a big change to me. Especially when the consequence of the re-positioning is to achieve syntactically what everyone is supposed to assume from the previous ordering. I'll leave it up to you! I certainly don't want to make anyone's life difficult or delay the approval process for end-points.

I don't suggest that we try to change the text for MPI_COMM_CREATE, either as part of this ticket or separately.

Cheers,
Dan.

Hi Dan,

Thanks for the thorough feedback.  I applied these changes and attached an
updated document.  I'm trying to keep the changes we make right now as
small as possible so that we can have a first vote in Japan.  The change
below is reasonable, but I'm concerned that it might push us over the
re-read threshold.

%%PROBLEM
The statements about cached information, valid values for my_num_ep, and
the condition for the error code/class all apply to the inter-communicator
case as well as the intra-communicator case. Should this be made clearer by
moving that text out of the intra-communicator paragraph and after the
inter-communicator paragraph?
%%SUGGESTION
If parent_comm is an intracommunicator ... sum of the values of my_num_ep
on all calling processes. If parent_comm is an intercommunicator ...
MPI_COMM_NULL is returned in all entries of new_comm_handles.
<p>No cached information ... this function will return MPI_ERR_ENDPOINTS
at all processes.

What are your thoughts?  I believe that the structure we have for this text
was inherited from the MPI_Comm_create text.
