Per http://meetings.mpi-forum.org/secretary/2009/09/agenda.php, the MPI-2.2 voting session is Fri, Sep 4, 11-11:30am Helsinki time. Sorry, I thought Bill had sent out the webex info for the voting session, but I think he got caught on a plane when I sent him the info. I'll forward it to the list shortly.

This would, in my opinion, rush the development of proposals as well as their discussion. Also, by cramping this so much together and assuming that most proposals that could make this deadline and should be included sooner than later make it, the forum will have a large number of big proposals to go through at a single meeting. > years, as I took it from the discussions that everybody present was > reluctant to have another intermediate release.

Re: [Mpi-forum] Deadline for next year's release
by Graham, Richard L. 02 Sep '09

What was said today is that we would like to have a first release of new MPI functionality 3 years after the start of the current forum, which will be around SC'10. This keeps with the current trend of an annual update. To meet this goal, first reading needs to be next spring. What does not make it into that release will need to be a year later, as we want to get nonblocking collrctives out the door.

Hi all, maybe just to add to Torsten, who wrapped up the discussion quite well. - we (here in Helsinki) agreed that it is vital to get some things out to the user soon (like the NBCs) and not have them wait all the way, till MPI 3.0 is settled - we did not agree, yet, what name such a release would have: 2.3, 2.9, 3.0, ... (that is to be discussed) I think the main message of Jeff's earlier mail was: If you want to get your stuff out soon, you will have to get it to the first reading by march, or you will have to wait till the "big package" is passed in 3 years, as I took it from the discussions that everybody present was reluctant to have another intermediate release.

From what I > have seen, I doubt other WGs will get beyond that... we talked about a staged release, possibly also MPI 2.3. I don't think that we rush anything. I'm positive that the FT group could have a proposal for consistent error codes and smaller things that are very important for FT by this time. Other groups like the Hybrid WG could also have something. And even if we don't have anything, what can you say against releasing a smaller incremental version with just NBCs and minor things. There was an objection that doing another MPI 2.2-like effort would cost a lot of the MPI 3 energy. While I fully agree to this, I'd say that this seems to be a question of policy. We decide what we discuss (and we should have a good clean base now). I would also like to have NBCs in an MPI release that does *not* break API compatibility. The burden on the user who wants to use NBC would be too big (imagine that you had to rewrite your 10^6 SLOC MPI program to run with MPI 3.0 just because you want to use NBCs). A good example for such an API breaker is the necessary MPI_Count discussion. A staged release would also ensure easy implementation and the timely availability of the compliant MPI implementations (I suspect that we will see MPI 2.2 adoption rather soon). I am really against rush here, we have to evaluate every new proposal as rigorously as we evaluated NBCs. If a proposal fails the March "deadline", then it will simply float into the next release.
