Hi all, I’m not really sure how to respond to this email.  I will just note that this proposal has passed 1^st vote last September with the following results.

4. Vote topic: MPI-2.2 const for C bindings, 1st vote:

YES:	17
NO:	4
ABSTAIN:	6
MISSED:	0
Result:	Ballot passed

http://meetings.mpi-forum.org/secretary/2008/09/votes.php

since then we decided to postpone the 1^st vote to add very few minor correction to ticket #46 (the original proposal) and thus created ticket #140.

I believe that all the points you mention below have been discussed in the forum meeting(s).

Thanks,

.Erez

Subject: [Mpi-forum] The const proposal - Ticket 140

All -

The signatories of this letter represent the majority of MPI implementors participating in the MPI Forum. We are concerned that proposal #140 ("Add const Keyword to the C bindings") has a number of issues which suggest delaying to MPI-3 would be appropriate.

In particular, the proposal:

- Is likely to pass a simple majority vote, but does not carry the support of the majority of MPI implementors, suggesting consensus has not been reached.
- Changes 90+ MPI API interfaces, which is not a "trivial" change and therefore does not meet the intent of the MPI-2.2 process.
- Is not needed to fix any serious bug in the standard text or to solve an issue that cannot easily be avoided by the MPI application.
- Does not offer any demonstrable optimization opportunities for implementation or application, but may constrain future implementation opportunities.

Therefore, we ask for your assistance in deferring proposal #140 to the MPI-3 process, where more time can be spent assessing its impact.

Thank you,
