Torsten: One comment on recent changes -- because of the matching rules, I am not convinced that nonblocking collectives are always sufficient to eliminate the problem of cyclic dependencies. I think the text added to page 66 based on Christian's comment could use a little tweaking. Specifically, I suggest: page 66, line 26: Nonblocking collective operations can be used to avoid such problems. change to: Nonblocking collective operations can alleviate this issue. or: Nonblocking collective operations can alleviate this restriction. Otherwise, things look good although we still need Adam's changes to the introductory NBC text before we can review... Bronis On Tue, 27 Jan 2009, Torsten Hoefler wrote:

Hello, I finished revision 2 of the NBC proposal based on discussions in today's telecon and several reviews.

The document is attached to ticket #109: https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/109

and for fast access temporarily: http://www.unixer.de/sec/nbc-proposal-rev-2.pdf the diff-file is: http://www.unixer.de/sec/nbc-proposal-rev-2.diff

Please review the changes carefully and send me any comments until the deadline on Friday, Jan 30th!

I also added a list of attendees to the wiki-page. I did not ask this time, so please let me know if I forgot somebody.

Thanks & Best, Torsten
