<p class="MsoNormal"><span style="font-size:11.0pt">Some notes from the 7/29/19 webex.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Dan pointed out a conflict about info keys – namely how they will be accessed before MPI initialization<br>
and after MPI finalization. Dan and Mark-Andre had discussed at ISC and were of the opinion that
<br>
changes for MPI info keys should go into the sessions (PR 55) proposal. Sessions is being considered as<br>
a gating factor for 4.0. We need to figure out what is the difference between the info object changes<br>
in the. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Aurelien says all the FT WG is wanting is to have MPI_INFO_ENV available before MPI initialization so<br>
the app can figure out what error handler has been set. Tools and Sessions don’t really care so much<br>
about this being available or not before MPI initialization. Dan discusses compromise that Sessions<br>
has taken. Wesley says FT needs MPI_Error_class and MPI_Error_string to be invocable
<br>
prior to MPI initialization as well. Aurelien thinks this is in PR 50.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Dan thinks the issue of argc/argv and how to fill in MPI_INFO_ENV is the key question.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Aurelien thinks maybe add a new function to set MPI_INFO_ENV? Maybe a new ticket to handle<br>
this. FT group will work on this.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Dan says we need to go through discrepancies between tickets. Sessions will need to pull in some of
<br>
the FT adds to callable-prior-to-MPI Init to the table in Chapter 10 of PR 55.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Mark-Andre raised some concerns about MPI_Info_get and error cases, but we think this will be
<br>
covered by the setting-default-error handler before MPI initialization approach.
