[Mpi3-tools] New MPI_T draft available
by Martin Schulz 26 Apr '11

26 Apr '11

Hi all, I have uploaded the new draft for the MPI_T interface to both the tools WG Wiki and to ticket #266. The text is also committed to SVN. The document now includes chapter 8 to mark a few minor necessary changes. Additionally, planned changes to Appendix A and the change log are marked in the ticket 266 itself. Hopefully this covers all the official requirements. The text itself got messy with all the change macros. If anyone has ideas on how to clean this up, that would be great. Thanks, Martin ________________________________________________________________________ Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulzm CASC @ Lawrence Livermore National Laboratory, Livermore, USA

[Mpi3-tools] Cancel TelCon tomorrow / Feedback on Draft Wanted
by Martin Schulz 25 Apr '11

25 Apr '11

Hi all, Since nobody has brought up any particular issues, let's cancel the TelCon planned for tomorrow morning. However, any additional feedback on the current draft of MPI_T would be great, preferably by noon PDT tomorrow. I will then compose a new draft and post it to the overall MPI list tomorrow evening, in time for the two week window. I have uploaded the latest draft, which now includes examples (Kathryn: your changes are not in there, yet, I will add those tomorrow). In particular the examples and the new data type section could use a few additional critical pairs of eyes. Thanks!

[Mpi3-tools] New MPI_T draft and next meeting
by Martin Schulz 22 Apr '11

22 Apr '11

Hi all, I have uploaded a new draft for MPI_T to the tools Wiki and also checked it into the WG space in SVN. This new draft should address all changes from the last reading, except for examples, which I will add over the weekend. Also things like the change log, changes to other sections of the standard, and changes to the appendix are missing for now. The main text should be complete, though. If any of you have time to make a pass before Monday (when we have to upload the document for the MPI forum) that would be great. If you are editing for grammar, feel free to directly change the TeX file. In this case, please coordinate through this list to avoid conflicts. Also, please use the following macro to track changes: \MPIreplacet{3.0}{<date, e.g., 11/4/21>}{<old>}{<new} Especially the changes to the type system could use a few critical eyes. As for the next meeting - we have it scheduled for next Monday, but unless major technical issues come up during the review of the document, I would propose to skip it. If there are issues, though, let's use the time to discuss them. In this case, I would be a 15-20min late, but Kathryn has agreed to run the call and the discussion (Thanks!).

[Mpi3-tools] Next MPI-3 Tools Telcon 4/4/11
by Martin Schulz 03 Apr '11

03 Apr '11

Hi all, Following our regular schedule, our next MPI-3 Tools TelCon is scheduled on 4/4 at the usual time 8am PDT, 11am PDT, 5pm MSZ. Jeff has again setup a WebEx meeting: https://cisco.webex.com/ciscosales/j.php?ED=162111667&UID=0&PW=NN2Q3ZjBlODU… Password: tools At the MPI forum last week, we had the first reading for MPI_T and generally, it went pretty well. However, there were a few points that need to be addressed and that we need to go over during the TelCon. - The forum wanted a closer integration into the standard. Some of this can be done with small language changes, but in some cases we have similar concepts in MPI and MPI_T and we are asked to make them the same if possible (or add more rationale on why they have to be different): - Error model / use of MPI error handlers - Use of MPI types (must be usable before MPI_Init) (Jeff is looking into the implementation complexity for Open MPI) - How does the API deal with counter overflows? How is this indicated to the user? Perhaps just an attribute saying that a counter can overflow? - How can we add to existing categories (e.g., when variables are part of lazy loads)? Should we also allow shrinking? - Should we add the option to atomically read multiple variables? - What text changes do we need to make to the overall MPI standard? Other edits that are missing - Add additional performance variable class to show resource limits - Make clear that indices can change between runs - Add MPI_Info/MPI_Message to list of MPI objects - Examples are still missing In addition, it would be good if more people could read the text for grammar and other small items. If you would like the TeX file, but don't have access to the SVN, let me know.
