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-repor... and https://svn.mpi-forum.org/trac/mpi-forum-web/attachment/ticket/229/mpi-repor... 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.

1) semi-official reading - intended to shake out any issues. 2) review by chapter committees, including working through any changes (which may include such things as adding rationales, as was recommended with the const proposal). 3) the formal reading, done as described below, but with a summary of the chapter committees 4) voting as usual.

Good point - the issue I have with it, is given that number of changes this has taken over the last several month, and the increasing number of request for consideration coming before the Forum, I would like to keep from asking the chapter committees to review material, until we are rather sure that ideas are acceptable to the forum, and implementation is essentially in the final form. Maybe all that is required here is to use the term "formal reading" in a much more conservative way that we have been doing, and really reserve it for readings of material that has been well vetted with the Forum.

I agree with using a process that doesn't require reading each individual change. However, the chapter authors should also review and agree; if they are not comfortable with Fortran, they need to find someone (not already reading the changes) to whom they can delegate the review.

Since the proposed changes to the Fortran bindings are extensive, we would like to propose a different method of handing their formal readings, so that people don’t have to sit through many hours of reading. Please let me know if there are objections to the proposal by August the 5 th if there are objections to this proposal, and you would prefer to have the full forum go through the entire text changes at the meeting.

Here is the proposal: Rolf will apply that changes, as required, to the standard, with Jeff and, Craig reviewing the changes. In addition, Hubert and Puri will also review the changes as outside reviewers. A second round of changes and reviews will take place and complete by Sept the 4 th , in time to meet the 2-week time period to post the proposed changes. If others want to participate in the formal review, you are more than welcome – just let either Rolf or me know. At the meeting in addition to the overview describing the changes, the reviewers will report back to the entire forum on their findings.
