Just a reminder that the room block is available until May 31st, and at this stage we are behind even the reduced room block that in the last meeting we had concluded we would need. If you are planning to use a room out of this block, please do so ASAP. Thanks, Rich

Hi Bin, > What was the decision on the ownership of array parameters in vector type > nonblocking collectives? > I did not find related discussions in the posted PDF. Thanks, that was discussed and we decided to leave the ownership to the library, i.e., the user is not allowed to change displs or counts. However, since this is not a minor change and we already voted on the document, we decided that we would need to file this as a separate ticket. I just filed a ticket: https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/223 The change is obvious and non-controversial and the solution is trivial. I hope we can read it at the next Forum meeting together with the draft chapter.

Hi, Torsten, What was the decision on the ownership of array parameters in vector type nonblocking collectives? I did not find related discussions in the posted PDF. Thanks Best Regards Bin Jia Communication Protocol Development Advanced Clustering Technology Team, IBM STG Poughkeepsie, NY 12601 Tel: 845-433-6301(T/L 293-) From: Torsten Hoefler <htor(a)illinois.edu> To: mpi-forum(a)lists.mpi-forum.org Date: 05/16/2010 02:24 AM Subject: [Mpi-forum] Final version of cleaned up Chapter 5 (Collective Operations) including NBC Sent by: mpi-forum-bounces(a)lists.mpi-forum.org Hello Forum, I did the manual cleanup as I promised to Rolf. All MPI-2.2 macros are now gone. The diff of the source code to Rolf's cleaned up version is now as short as it will get. Please check the diff carefully. I used the macros that Bill introduced in MPI-2.2 (replacing "2.2" with "3.0") to mark the changes from #109. I also fixed a number of excess spaces (" ") in my editorial freedom. The chapter is in the MPI-3.0 repository. To look at the diff, do: svn diff -r495:HEAD in the subdirectory chap-coll. I put the diff at http://www.unixer.de/sec/mpi_chap_5_diff_459-HEAD.txt . The full standard-draft that we will vote on at the next meeting is in the svn and at http://www.unixer.de/sec/mpi-report.pdf . Please let me know if you have any questions or find any problems!

Re: [Mpi-forum] I can not make MPI recognizes a dual core
by Jeff Squyres (jsquyres) 21 May '10

This list is more about the standards body for MPI, not so much general user questions. Your question is better posted to whatever the relevant support mechanism is for your MPI implementation. For example, if you're using Open MPI or MPICH, there are public mailing lists when you can send your question. If you're using a vendor MPI implementation, you might want to try your support channel with them. Good luck! -jms Sent from my PDA.
