Dear chapter authors, Fortran reviewers, and authors of MPI-3 tickets, I sent this also through the Forum list, because some of the MPI-3 ticket authors are missing in the individual list. And there may be others with interest on Fortran+MPI.

Please, now I need your help for the reviewing process. https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/ticket/229/mpi-repo… and https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/ticket/229/mpi-repo… All these pre-reviews should be done until Aug. 31. Please print the pages simplex where you make comments, scan in and please send the scanned pdf back to me. Longer new texts please also be email. Please use the changeonlyplustickets.pdf for commenting because it is more readable. For a precise review, you may also want to look at 'all' the deleted texts in the full reviewdoc.pdf This is only a pre-review, i.e., your wishes can be included in the version that will be published 2 weeks before Santorini for final reviews reported at Santorini. Please check you chapter very carefully. Not finished issues in this version: - Callbacks in mpi_f08: - The abstract interfaces will be will be BIND(C) - We check for abstract interfaces with TYPE(*), DIMENSION(*) for the two callbacks with choice-buffers - Tools and linker names: - we must allow to have duplicate versions for with/without TR29113 only for the choice-buffer routines - Cray-Pointer on MPI_ALLOC_MEM will be deprecated, i.e., overloading is only with mpi module, mpi_fo8 will have only the new interface. But same interface for MPI_Free_mem for all three methods. - String-OUT-arguments with fixed lengths were possible. - Example for splitting data to allow overlapping of communication and computation without hurting the ....affector rules for the ASYNCHRONOUS attribute. Next steps: - You review until Aug.31 Please print the pages simplex where you make comments, scan in and please send the scanned pdf back to me. Longer new texts please also be email. - I put in your review results between Sep.1 and Sep.8, I work page by page, therefore I need these scanned printouts. - Sep.8: Final version for official reading and your final reviewing. - Sep.21: Your final review should be finished - Sep.22-24: you or somebody acting for you will present your review in Santorini.

About the Sep.-meeting 2012: We have only a few statements on date at EuroMPI 2012 with mainly two alternatives next year 2012: - MPI-3 Wed-Fri Sep 19-21 + EuroMPI Sun-Thu Sep 23-26 with free whole Saturday; - EuroMPI Sun-Thu Sep 23-26 + MPI-3 Fri-Sat Sep 27-29 (6 day work for those who omit the conference tutorials with free Fri-morning). I believe, we should decide this at the next meeting, with additional votes as reply to this mail from those who want to come 2012 but cannot come to Santorini. -------------------------------- Date: Aug 24, 2011 Sept 19-21: In conjunction with EuroMPI Rich -------------------------------- Darius Buntinas: I too would prefer September 27-29. -------------------------------- For me, the weekend before is already filled (and the event is already booked).

Just a reminder that the current agenda is posted at http://meetings.mpi-forum.org/secretary/2011/09/agenda.php There are still several slots available, so if you would like a slot, please let me know in the next week or so. I have a request for a large block from the Fortran working group, so will give them the rest of the time if no other requests appear. Rich

Re: [Mpi-forum] Glossary for MPI-3

Hello, Attached is a pdf version of the glossary for MPI-3 -- I would like to encourage folks to review it if possible before the upcoming September meeting. >From this point on, please direct all glossary comments and/or suggestions to either the wiki ticket (https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/78) or by email directly to trj(a)ornl.gov. The most current tex and pdf glossary versions will be maintained at ticket #78. Thanks, -Terry On 7/6/11 2:51 PM, "Terry Jones" <trjones(a)ornl.gov> wrote: Hello All, I believe it would be a helpful to include a glossary with MPI-3, and I'd like to solicit help in constructing a draft for a future reading. Among the reasons for including a glossary are: (a) Promotes precise usage of MPI concepts and specialized terms. (b) Convenience - especially for new users. (c) Can be used to help ensure consistency in use of functions, operations, etc., if done well. One often hears imprecise usage for important MPI concepts. For example, since MPI uses the term "process" differently than one might anticipate based on experience with the Unix notion of "process", the distinction becomes important. I was recently in a telecon where the distinction between ranks and processes was highlighted. A glossary can be a convenient and very helpful place to review MPI term usage. My thought is to use exact text from the various chapters, including helpful figures, and place them in an ordered list for the back of the document. I'm not sure which mailing-list would be appropriate to carry subsequent updates/dialogue for this topic (perhaps mpi3-misc?). A history of this topic can be found in Ticket 78 (https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/78) To realize an MPI-3 inclusion we need to be making progress now. Please let me know if you would like to participate in preparing text for a future reading by emailing me directly (trj(a)ornl.gov) My goal is to have something prepared by the Fall/early-Winter timeframe.

For me, the weekend before is already filled (and the event is already booked). I automatically expected the usual rule: After EuroMPI, Sep.27-29 (3 days) or Sep.27-30 (4days) Most of us do not attend the EuroMPI tutorials, therefore with EuroMPI talks + Forum only 3 days, we have in total a 6 day week which is still okay and reduces total travel time and costs.
