For these info keys, the benefit is fairly straightforward. For communicators with wildcard restrictions you can use a structure that is much more efficient to search than a single ordered list. In addition, when you have multiple communication channels (e.g. shared memory, multiple rails, etc) no_any_source removes a lot of complications and overheads.</div><div><br></div><div> ~Jim.</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Thu, Nov 20, 2014 at 2:09 PM, Daniel Holmes <span dir="ltr"><<a href="mailto:dholmes@epcc.ed.ac.uk" target="_blank">dholmes@epcc.ed.ac.uk</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5">

Hi All,<br>
<br>
One of the objections last time was that these keys seem like a good
idea for performance but there's no implementation/proof. We'll need
to collate some of the existing research that shows this gives a
performance benefit in order to address that objection.<br>
<br>
Cheers,<br>

<div dir="ltr">Hi All,
<div><br>
</div>
<div>I would like to bring forward the following ticket on
communicator info keys for a formal reading at the upcoming
meeting: <a href="https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/461" target="_blank">https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/461</a>.</div>
<div><br>
</div>
<div>This ticket contains the no_any_tag and no_any_source info
keys from #381 on which we were able to reach consensus.
There are lots of other good ideas on #318, and we will
continue to work on moving those ahead.</div>
<div><br>
</div>
<div>Please send feedback. The deadline for changes to the
proposal is Sunday.</div>
<div><br>
</div>
<div>Thanks,</div>
<div> ~Jim.</div>
