Hi Jim,<br>
<br>
Yes, that was (and still is!) the intention. I haven't yet created a
branch in SVN for the new version of the standard and that's the
first step toward getting the text more prepared than we already
have it. We are sufficiently close to something we could read that
it would be a shame to miss the June deadline. I will attempt to
find some time this week to work on this.<br>
<br>
Cheers,<br>
Dan.<br>

<div>At the last meeting, we came up with a proposal to allow
info to be used for assertions. Should we work on pulling
that together as a formal proposal, to read in June?</div>

<br>
I am cancelling the point-to-point teleconference today
because I have not had time to progress the work on
communicator assertions since last time and I am not
aware of any other ongoing work for us to talk about.<br>
<br>
Looking forward to figure out when the next meeting will
take place, I won't be available for the next two
teleconferences due to travelling. This means that the
next meeting date would be 25th May, i.e. one week
before the face-to-face meeting in Chicago.<br>
<br>
I will send out a reminder nearer the time and will
communicate any progress in the interim via email.<br>
<br>
Cheers,<br>
Dan.<br>

Agenda:<br>
0) Discuss/agree the to-do list (see below) that
covers the next two agenda items.<br>
1) "Can INFO keys change the semantic behaviour of
MPI?" issue - following the discussion at the
face-to-face meeting, we seem to have a workable way
forward on this issue!<br>
2) New communicator INFO keys - it looks like these
will be allowed, so we should define a few and get a
proposal ready for the next face-to-face meeting<br>
3) Progress on Arecv and Fsend or ReceiveReduce?<br>
4) Other stuff?<br>
<br>
Cheers,<br>

At the last telco meeting, Jim asked for a to-do
list of the tasks needed to move communicator
assertions forward. Please find below a first draft
of such a task list. Could we agree that this is a
good list? If you see something odd/missing, reply
to this email group.<br>
<br>
<u>To-do list for communicator assertions</u><u><br>
</u><br>
0) Gather evidence to support "no-one will be
affected by backwards incompatibility".<br>
(e.g. chase Pavan, who volunteered to do this for
major MPICH users)<br>
1) Change behaviour of MPI_COMM_DUP so that INFO
keys are *not* propagated to new comm.<br>
(include AtoU: if you want to dup INFO use
MPI_COMM_DUP_WITH_INFO, with example)<br>
2) Discuss whether attributes (plus, anything else?)
should be propagated by MPI_COMM_DUP.<br>
(default presumption is yes, they should still be
propagated).<br>
3) Find all occurrence of language in the MPI
Standard that suggests INFO keys are hints.<br>
a) Change or remove any generic statements like
"INFO keys cannot change semantics".<br>
(e.g. change to "cannot change observable
semantics" or remove)<br>
b) For each occurrence, determine if it should
continue to suggest hint status<br>
(e.g. a particular key, most likely for the I/O
keys but maybe also some RMA keys)<br>
<br>
A) Convert ticket 381 into "make comm assertions
doable" proposal (by Jun 2015 - Chicago?)<br>
B) Get "no wildcard" INFO keys proposal ready for
formal reading (by Jun 2015 - Chicago?)<br>
C) Get "no ordering" INFO key proposal ready for
formal reading (by Jun 2015 - Chicago?)<br>
D) Get "no cancel" INFO keys proposal ready for
formal reading (by Jun 2015 - Chicago?)<br>
E) Discuss other INFO key proposals, e.g. "only
wildcard", "no non-blocking", "no underflow"<br>
<br>
Cheers,<br>
Dan.</blockquote>
