Hi Rich,

Here’s the description for the two items we have on the list:

Const: make C bindings const-correct, except where backward compatibility would be broken.

MPI_Count: Minimal support for large datatypes.

One more thing.  Those of you that have an item on the list (and those that are adding items) - please send me a 1-2 sentence explanation that we can use as a description.

Thanks,
Rich

Subject: [Mpi-forum] MPI 3.0

At the MPI forum meeting this week we decided to accelerate the release of MPI-3.0, and have a follow on MPI-3.1 when the more complete set of features is available.  Currently, nonblocking collectives and MProbe have already been voted in.  We have created a list of features that may be ready for first reading at the next couple of meetings, which will be used to determine the gating factors for the MPI-3.0 release.   Here is the list we generated:
  - RMA
  - FT stabilization
  - Fortran bindings
  - MPI-T
  - Neighborhood collectives
  - Const
  - MPI Count
  - Nonblocking collective I/O
  - Hybrid: Shared memory communicator
  - Hybrid: Threads
  - Hybrid: Endpoints

If people want to add more to this list, please let me know by end of the day Friday, 5/13/2011.

Once we have the complete list, each eligible organization should vote for it's top three features, with respect to MPI-3.0.  An organization is eligible to vote, if someone from that organization has participated in person at one or more meetings in 2011.  The vote will take place 5/14-20/2011, and the top three items will be what gate the release of MPI-3.0.  To vote, a representative of the organization should e-mail BOTH Jeff Squyres and myself with your vote.  Other items that are voted in before 3.0 is final, will also be included.  For MPI-3.1, we will change our process a bit, but that is still under discussion, and will be the subject of a future e-mail discussion.

The eligible organizations include:
 - ANL
 - Bull
 - Cicso
 - Cray
 - Fujistsu
 - HDF
 - HLRS
 - HP
 - IBM
 - Indiana U.
 - INRIA
 - Intel
 - LLNL
 - LANL
 - Microsoft
 - NCSA/UIUC
 - ORNL
 - OSU
 - Oracle
 - SNL
 - U Alabama Birmingham
 - U Tennessee
 - U. Tokyo
