<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Unfortunately, I am double-booked for tomorrow’s HACC WG time slot – so my answer to the implied question below is “not yet”.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">The “logically concurrent isn’t” issue #117 is now accepted and merged into MPI-4.1 (take a moment to celebrate!) – but it just says “here be dragons”.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Do we care enough to defeat those dragons?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Argument FOR: as systems become more heterogeneous, an MPI process is likely to abstractly “contain” more semi-independent HW units that will want to communicate with other MPI processes, which will
result in lots of logically concurrent MPI communication operations – exactly the territory in which these dragons live.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Argument AGAINST: we’ve been throwing brave warriors into this particular dragon fire for about a decade and we’ve only now convinced ourselves that the dragons do, in fact, exist. How many more
volunteers do we have and do they have sufficiently pointy sticks?<o:p></o:p></span></p>
