<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">I have created a global vector V using DMCreateGlobalVector of size m. For n processes, the local size of V is m/n.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Subsequently, I am using VecScatterCreateToAll to get a sequential copy of the V, let's call it V_seq of local size m. It passes through a function and outputs the vector V_seq_hat (of local
size m).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">Is there a way for me to substitute the values of V_seq_hat (at the correct indices) to the original V (with local size m/n)?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">When I use VecScatterCreateToAll (with SCATTER_REVERSE), I am getting a vector V with new values from V_seq_hat but with local size m. This is causing issues in the rest of my code where the
size of V needs to be m/n.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
