Re: [Mpi-forum] Process for handling of such comments - Fwd: [Mpi-comments] One comment on MPI-3.0 Draft 2, August 2012

The plan is to go over the comments and make any changes we agree on by the 12th, giving people a week to go over the document before the final votes. Small edits will go to chapter committees for their review, and if there are large items, we will need to have a telecom on the 10th of Sept to decide if and how to respond. So far, there have been only 1-2 minor comments.

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.

Rich -- were you going to send out formal notices about posting the draft? We iterated over the text of the announcement a while ago; I think it was Alexander who suggested the best version (http://lists.mpi-forum.org/mpi-forum/2012/07/2075.php) I took the liberty of updating http://meetings.mpi-forum.org/MPI_3.0_main_page.php: - fixed all the broken HTML - made the draft 2 announcement more prominent - clarified the text of the announcement - moved the draft PDF to the same directory as a) draft 1 and b) prior discussions of where it would be located - added a sym link to the old location of draft 2 in case anyone keeps looking for it there On Aug 3, 2012, at 2:03 AM, Richard Graham wrote: > The draft standard is posted ï¿½ please have at it. > > Rich > > > > > > > _______________________________________________ > mpi-forum mailing list > mpi-forum(a)lists.mpi-forum.org > http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi-forum -- Jeff Squyres jsquyres(a)cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
