Hi All,<br>
<br>
The next point-to-point teleconference will be today, Monday 30th
March 2015 at 11am Central US via webex.<br>
<br>
Connection details are on the point-to-point wiki page:<br>
<a href="https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/PtpWikiPage" target="_blank">https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/PtpWikiPage</a><br>
<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>
Dan.<br>
<br>

Hi All,<br>
<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.<br>
