[Mpi-22] please review - add const keyword to the C bindings

[Supalov, Alexander]

Dear Bronis,

Thank you. Intel position on these issues has not changed a jot. We've been consistently against them from day 1, and consistently voted them down, for reasons I mentioned elsewhere.

The new memory remapping scenario that highlights how detrimental the proposed changes may be to the MPI implementations was added after the first vote because this occurred to me after substantial contemplation. This happens to all of us once in a while I guess.

In my opinion, continuing the work on wording is OK as long as the substance is OK. In this case, I believe the substance is not OK. This is why I'm suggesting to suspend the work on wording until we all agree that the matter is OK in principle.

If you disagree, this will be your decision. I'm not going to be at the next meeting and am using the medium available to me to promote our point of view. I hope this is OK with the Forum at large.

Best regards.

Alexander

While it is within your rights to suggest that we "suspend
the review" of these items, I object to your timing. The
issues have already had a first vote. You can raise concerns
about them but I see no reason that we should cease to
make progress on the wording when the vast majority (I
don't recall if the vote was unanimous but it was not close)
have agreed to them.

Perhaps more importantly, your objections have been discussed
from the first that Erez brought up the issues. Frankly, I
have not seen anything in your objections that changes the
extensive discussion on these issues. While it may be that
you have changed your position (and Intel's?) on them, I
strongly doubt that others will be convinced.

In my opinion, Erez should definitely proceed with the
reviews. If you want to object to the solutions, you will
have an opportunity when the issues come up for their second
vote the week after next.

Bronis
