I am starting a new thread with the appropriate subject header to separate out the discussion on this topic. I have also cc'ed the collective communications group and removed the semantic terms group for this discussion.<br>

<div class="" style="word-wrap:break-word; line-break:after-white-space">Hi Puri,
<div class=""><br class="">
</div>
<div class="">Thanks for this - a great way to provoke some progress (no pun intended).</div>
<div class=""><br class="">
</div>
<div class="">I would suggest: move the rows dealing with MPI_PREADY and MPI_PARRIVED between MPI_START and MPI_WAIT, i.e. in the approximate calling order.</div>
<div class=""><br class="">
</div>
<div class="">Also, I would add ic for the new MPI_PREADY, MPI_PARRIVED, etc procedures - because the operation is definitely incomplete at the point in time they are called, during the time interval of their entire execution, and at the point in time they
return - there is no possibility they could be completing or freeing procedures.</div>
<div class=""><br class="">
</div>
<div class="">What are the other footnotes: 7, 9, and 14? (I could look them up but Id have to choose the same draft version as you because the numbering changed recently.)<br class="">
