Sept Forum meeting
by Richard Graham 10 Sep '12

10 Sep '12

All, If you plan to attend and have not registered, please do so ASAP. There are several folks that I believe are coming who have not yet registered - it is very helpful for those planning the logistics to have a reasonable head count. If you do not want to commit by registering, but do think you will come, letting me know is also helpful. Thanks, Rich

MPI 3.0 - Last Call
by Richard Graham 10 Sep '12

10 Sep '12

At this stage I am aware of only one set of outstanding changes that still need to be committed (some of the Fortran changes). PLEASE, if you have any other corrections that you plan to make, let me know ASAP. If I do not hear otherwise by 5 pm Eastern time today (Monday, Sept 10th, 2012), I will create the draft we will vote on based on what is in the repository. Thanks, Rich

Rich, I already updated my overview slides on Aug.21, but it looks like that I forgot to send it around. I tried to make correct courtesy-notes, but I'm not sure. The slides are partially based on an old version from you which was based on chapter committee's or author's slides. I'll send you the ppt and all who want to get the ppt may sent me a short reply.

Re: [Mpi-forum] Review of Minor updates to the standard

Feel free to send me material for review. Rich ----- Original Message ----- From: William Gropp [mailto:[email protected]] Sent: Friday, September 07, 2012 01:08 PM To: Main MPI Forum mailing list <mpi-forum(a)lists.mpi-forum.org> Subject: [Mpi-forum] Review of Minor updates to the standard I have updated this material, based on the public comments: Front matter Chapter 1, Introduction Chapter 6, Groups, Contexts, Communicators, and Caching Chapter 11, One-sided Communication I would like some reviewers for the first 3 (I've made the RMA chapter available to the RMA group). These three chapters do have chapter committees, but they've been inactive, so I'd like some volunteers. I have the svn diffs of the chapters as well as the PDF for the chapters, with the updates in color. The changes are almost all minor typos, with a few corrections (e.g., there was one statement about the inability to add processes to an MPI job that was true in MPI 1 but hasn't been true since MPI 2.0). Let me know if you can help. Thanks!

With the exception of the Dynamics chapter (which is imminent) and the change that Rajeev queried the forum on, I believe all other changes are done.

Final MPI 3.0 document
by Richard Graham 06 Sep '12

06 Sep '12

All, Today is the last day for comments on the current standard draft. At this stage I am aware of two sets of corrections that I do not believe are complete: - Changes to Dynamic Process Management chapter (coming very soon) - Fortran corrections: do not know what the state is here - The RMA group is mulling some clarifications (how close are these to being complete ?) Are there other corrections that folks are working on ? I would like to post the version that we will vote on ASAP. I know that we gave ourselves about one more week, but the earlier the better, as we have been making corrections as comments have come in. Thanks, Rich

reverting a change made by ticket 281 (remove C++ bindings)
by Rajeev Thakur 05 Sep '12

05 Sep '12

In the section on external32 data format on pg 536, ln 30-31, ticket 281 (Remove C++ bindings) removed the words "and C++ bool" in this sentence: "For C _Bool, Fortran LOGICAL, and C++ bool, 0 implies false and nonzero implies true." ^^^^^^^^^^^ However, the "and C++ bool" is needed because MPI-3 still supports C++ types (see the tables below, the first is on pg 27, and the second is the lengths in external32 format). So, any objection to reverting the change made by ticket 281 in the above sentence, i.e., add back "and C++ bool," ? Rajeev

If "Sparse" means "Neighborhood", then this is already supported in MPICH as well. -Dave
