Comment on RMA: MPIX_ERR_RMA_WRONG_FLAVOR
by Jim Dinan 07 Aug '12

Hi All, [ moving posting from mpi3-rma list to mpi-comments ] In the RMA chapter, we define an error class, MPIX_ERR_RMA_WRONG_FLAVOR. The use of "WRONG" in the error class name is inconsistent with MPI naming conventions and the new error class should be renamed to MPIX_ERR_RMA_FLAVOR. ~Jim.

Bill, we should do this. Especially when looking for 16.2.2 or any other subsection number, it is hard to find it in the pdf. With Jurgen Rusch's idea, it should work. Jurgen, (sorry, my previous mail had wrong destination) thank you for your proposal! Whether minor or not, we pipilene all helpful comments through this email. Therefore I forwarded it. Best regards Rolf ----- Forwarded Message ----- From: "Jurgen Rusch" <jurgen.rusch(a)philips.com> To: "Rolf Rabenseifner" <rabenseifner(a)hlrs.de> Sent: Friday, August 3, 2012 3:43:26 PM Subject: RE: MPI-3.0 public draft and call for comments Dear Mister Rabenseifner, I'm responding to you via this informal e-mail channel and not via the recommended way to subscribe to the MPI-forum and send a comment to mpi-comments(a)mpi-forum.org. The reason is that I have a very minor, more PDF related, remark which I explain next. When I opened http://meetings.mpi-forum.org/mpi3.0_draft_2.pdf I saw that the bookmarks as shown in the left part of Adobe Reader do not contain the chapter/section numbers: they merely contain the text of the respective chapter, section, annex etc. Having seen that this document has been written in LaTeX (File --> Properties in Adobe Reader shows that the application "LaTeX with hyperref package" was used) I would like to tell to you and the other MPI-authors, that the hyperref package has an interesting option called "bookmarksnumbered" (default: false) which, when true, causes the bookmarks to include the section numbers. This is an option I often use which makes the bookmarks nicely numbered. For more information please see http://www.tug.org/applications/hyperref/manual.html (section 3.6, "PDF-specific display options"). With this e-mail I hope to have contributed a little bit to the MPI standard (although only PDF related). With kind regards, Jurgen Rusch (a former student of you) ________________________________ The information contained in this message may be confidential and legally protected under applicable law.

One comment on MPI-3.0 Draft 2, August 2012
by Sébastien Boisvert 04 Aug '12

04 Aug '12

Dear MPI Forum committee members, I would like to submit a comment on the MPI-3.0 Draft 2, August 2012 for your consideration. Version: MPI-3.0 Draft 2, August 2012. The URL of the version of the MPI standard: http://meetings.mpi-forum.org/draft_standard/mpi3.0_draft_2.pdf Page: 65 Line number: 28 Section: 3.8.1 In: 3. Point-to-Point Communication 3.8 Probe and Cancel 3.8.1 Probe Comment: It says that the source argument of MPI_Iprobe can be MPI_ANY_SOURCE, but it does say anything about fairness. Therefore MPI_ANY_SOURCE can lead to resource starvation. I think it would be better if probing would be done in a round-robin fashion when the source is MPI_ANY_SOURCE so that any MPI rank has an equal chance of having its message probed and received. Presently, the MPI standard contains nothing about which source should be probed when MPI_ANY_SOURCE is provided. I hope you will consider my comment. Sincerely, Sï¿½bastien Boisvert PhD student Universitï¿½ Laval

Question

Hi, In a quick look to http://meetings.mpi-forum.org/mpi3.0_draft_2.pdf I read at the end of page ii: " c 1993, 1994, 1995, 1996, 1997, 2008, 2009, 2012 University of Tennessee, Knoxville, Tennessee. Permission to copy without fee all or part of this material is granted, provided the University of Tennessee copyright notice and the title of this document appear, and notice is given that copying is by permission of the University of Tennessee. " Is it right? If so, could you give a short explanation (or a link to) about the reason/s? Thanks in advance, Fernando. --- La parte gris de las zapatillas es bien resbalosa, con ï¿½sas voy como Flash por la baranda de la escalera.
