<p class="MsoNormal">Hello team,<o:p></o:p></p>

<p class="MsoNormal">I’m trying to use PetscViewerASCIIRead() to read in a single interger/scalar value from an input file. It works for one processor. However, when running on multiple processors, I’m getting the below error:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">[1]PETSC ERROR: Invalid argument<o:p></o:p></p>
<p class="MsoNormal">[1]PETSC ERROR: Insufficient data, read only 0 < 1 items<o:p></o:p></p>
<p class="MsoNormal">[1]PETSC ERROR: #1 PetscViewerASCIIRead() line 1054 in /usr/local/CLAB-2/petsc-3.6/src/sys/classes/viewer/impls/ascii/filev.c<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there something wrong with how I’m implementing this, or ASCIIRead does not work with multiple processors?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
