Okay, I will rework the Introduction today. Then it is done. In MPI-2.2, we can move misc-2.tex, the rest of ei-2.tex into other chapters. For MPI-2.1 that's enough what we have reached.

AUTHORS+REVIEWERS - Draft Apr. 12, 2008
by unknown＠example.com 12 Apr '08

12 Apr '08

Dear chapter author, dear reviewer, This e-mail is the first preparation of the official reading. Please read carefully. Again,we have a stable and consistent draft. It is SVN revision 108 and pdf and ps are on http://www.hlrs.de/mpi/mpi21/doc/ (username and password are mpi21) Nearly all chapters have received an update by the chapters' authors. Not finished is - as far as I can see - Point-to-point (may-be without MPI-1/2 problems] (Rich Graham) - Datatypes [it was split from Point-to-point] (Rich Graham) and full MPI-2 based chapters (maybe without need for updates) - Terms (Tony Skjellum) - External Interfaces (Bronis de Supinski) - Profiling (Bronis de Supinski) Therefore, review can start in all chapters, except the datatype chapter. IMPORTANT for authors: If you make further modifications, please be sure that you use the macros and that your modification (or at least an delete-anchor) is printed **red**. (Details on using the macros, see below.) Please check red color in the resulting mpi-report.pdf before you svn commit your changes. As far as I can see, all changes up to now may have no problem for acceptance by the Forum. At this late stage, I would recommend to do only changes that do not need intensive debates at the Forum meeting. Such things would be MPI-2.2 modifications. IMPORTANT for reviewers: - Please check very carefully all red or magenta changes. Modifications are done by the chapter's author (red) or by me (magenta). You may be the first reviewer who read and check this text. - Please check carefully the cyan text. Those modifications are proposed by a reviewer and have been implemented by my You may be the second reviewer for those modifications. - All green stuff should be fine, because it is based on Forum's decisions (Ballot 1-4). - Original text is black (MPI-1.3) or blue (MPI-2.0). - Please make all comments in the format ---------------------------------------------------------------------------------- 1234567890123456789012345678901234567890123456789012345678901234567890123456789012 All references are based on MPI-2.1 Draft Apr. 12, 2008 ww.a __ pnnn.ll text (with nnn=page number and ll=line number text continued ... ww.b __ pnnn.ll text ... and so on (total line length <= 82 characters.) ---------------------------------------------------------------------------------- - Please send only review items that are in the category -- ERROR, must be fixed. - If you want to send an item in the categories -- Nice to have, -- Editorial proposal (like move xxx to yyy), -- Clarification which needs Forum decisions, -- ... then please substitute the __ by 22, because then it should be handled in MPI-2.2. This format is used in http://www.hlrs.de/mpi/mpi21/doc/MPI-2.1draft-2008-02-23-review.txt where all reviews are filed in. (I'll substitute your xx by the next number. If you have more than 26 items, then please continue with xx.a -- xx.z, yy.a - ...) Please use this format. I'll have only a few minutes between two flights to put all reviews together. WORKPLAN: - The authors get back the write-token until Thursday, Apr. 17. (If you need also Friday Apr. 18, then please inform me!!) - All stuff that is not done until that point, will be defered to MPI-2.2! - I'm on travel and may not be able to respond on e-mails this week. - On Friday, Apr. 18 (or Saturday, Apr. 19), I will make the final version for all final reviews and for the official reading. - Version Apr. 17 together with all your review mails will be the basis for the official reading. - Reviews until Friday, Apr. 25. according the format above. - Saturday, Apr. 26: I will put all reviews together to have unique numbers. Best regards Rolf Annex: The rules for authors: The goals of your work as chapter author: ----------------------------------------- - Remove references to MPI-1 and MPI-2. - Substitute by MPI. - Necessary modifications to achieve this goal. With this, we should have a single MPI-2.1 standard that does not "know" the MPI-1 or MPI-2 history of individual functions. ** This should be mainly a task in the area of chapter-introductions. ** Please, never change the wording of function definitions. Exceptions: - There are routines that are deprecated and that are already referenced in a consistent way. My recommendation: Current wording: There are *new* function, and existing are now deprecated. Proposal: There are functions, and there exist also deprecated functions with (nearly) same functionality but deprecated due to some lack in the bindings (or functionality) - There is history information in the frontmatter. - there is a change-log annex with limited memory (only previous version) Technical editing rule: ----------------------- You must identify all of your changes: a) new/modified wording - you are highlighting your new/modified wording with: \mpiiidotiMergeNEWforSINGLEbegin% MPI-2.1 round-two - begin of modification .... your modified / new wording .... \mpiiidotiMergeNEWforSINGLEendI% MPI-2.1 round-two - end of modification b) Moved paragraphs, sentences, ... - you are highlighting the first word of the moved text with: \mpiiidotiMergeNEWforSINGLEbegin% MPI-2.1 round-two - begin of text-move First-word \mpiiidotiMergeNEWforSINGLEendI% MPI-2.1 round-two - ongoing text-move ... rest of the moved text.... % MPI-2.1 round-two - end of text-move c) If you want to delete text (i.e. not only a move to another location), the please us \mpiiidotiMergeNEWforSINGLEbegin% MPI-2.1 round-two - deleted-text-anchor Last word of the previous text \mpiiidotiMergeNEWforSINGLEendI% MPI-2.1 round-two - end of anchor % MPI-2.1 round-two - begin of deteted text - Draft Apr.1, 2008 page/line-page/line % the text you delete must be preceded with "% " % deprecated text % ... % deprecated text % MPI-2.1 round-two - end of deteted text Additionally, you must add this outcommented text to the end of removed_source.tex Caution: These macros work only in black parts of the text. In blue parts you must substitute \mpiiidotiMergeNEWforSINGLEendI% by \mpiiidotiMergeNEWforSINGLEendII% The highlighting is done with red color. (There are only a few other sentences from me magenta. Therefore red should be the best to highlight the round-two modifications.) ----------------------------------------------------- Using svn: Before you start to make changes: cd ....your_directory..../trunk/MPI-2.1/ svn update to get the newest sources. After you made changes, please call make and check mpi-report.pdf to guarantee that all your changes are really highlighted with *red* color. When you make the first svn commit after you received a new username with write-permission, you must use the aditional option --username your_new_user_name Please commit with vn commit chap-xxxx/xxxx.tex -m 'MPI-2.1 - your name - what you have done' Please commit as soon as you finished the changes and after you have checked the red color. -------------------------------------------------- Dr. Rolf Rabenseifner . . . . . . . . . .. email rabenseifner_at_[hidden] High Performance Computing Center (HLRS) . phone ++49(0)711/685-65530 University of Stuttgart . . . . . . . . .. fax ++49(0)711 / 685-65832 Head of Dpmt Parallel Computing . . . www.hlrs.de/people/rabenseifner Nobelstr. 19, D-70550 Stuttgart, Germany .

Hi Adam, this is really a good merge that you have done. Good ideas and very carefully implemented. The reviewers can see (nearly) all of your modifications in red. I expect that your reviewersand the Forum will enjoy your modifications. I have restored two minor mods you have done: (Line numbers refer to the new file you'll get with svn update) coll.tex, line 412 - I restored the "intracommunicator" because the categories describe the behavior only on intracommunicators, not on all, e.g., ALLGATHER has one result on intra and two on inter and the wording is "the result". coll.tex, line 491 - restored the word "also". These routines are valid for intra and inter. Writing "apply to inter" may be interpreted that they are only valid for inter. Writing "also apply to inter" should solve this problem. I also colored this sentence red. I hop, this isokay with you.

illegal and invalid
by unknown＠example.com 10 Apr '08

10 Apr '08

In reading through Rolf's excellent list of issues, I noted a comment about "illegal" datatypes. We really should use "valid" and "invalid" rather then "legal" and "illegal", since MPI is, at least not yet, the law :) Something for the 2.2 edits.... (The GNU Coding standards make a point of rejecting the use of illegal, BTW.) Bill William Gropp Paul and Cynthia Saylor Professor of Computer Science University of Illinois Urbana-Champaign *

AUTHORS: new consistent version and write-token to you
by unknown＠example.com 10 Apr '08

10 Apr '08

>> write-token again to the chapter authors << >> - but only until Saturday 8:00 European GMT << Hi all authors and reviewers, Please read this mail carfully, if you want to make any further modification of the text. You must now call svn update to get the newest release!! We have a again a consistent version. Nearly all of http://www.hlrs.de/mpi/mpi21/doc/MPI-2.1draft-2008-02-23-review.txt is now implemented in the tex-source. Only a few items are still open, see statistics at the beginning. You can view the current version (it is svn revision 92) at http://www.hlrs.de/mpi/mpi21/doc/mpi-report.pdf It is only today and Friday remaining for finishing MPI-2.1. I give back the write-token to the authors. On Saturday morning European time, I take the write-token automatically on Saturday morning to build final pdf for the reviews. As I can see, many chapter authors made fine cleaning to the text. All larger changes should be defered to MPI-2.2! Especially the merge of MPI Environment (inquiry.tex), Misc (misc-2.tex) and External Interfaces (ei-2.tex) to one chapter "MPI Environment and Miscellany" (with 45 pages) may be defered also to MPI-2.2. Up to now, I was able to check most changes and they look fine.
