<p>Dear PETSc people,</p>
<p>in PETSc 3.3 <br>
</p>
<p> call DMView( dm, PETSC_VIEWER_STDOUT_WORLD, ierr) <br>
</p>
<p>printed out the ownership ranges like so:</p>
<blockquote>
<p>Processor [0] M 32 N 34 P 32 m 1 n 2 p 2 w 1 s 1<br>
X range of indices: 0 32, Y range of indices: 0 17, Z range of
indices: 0 16<br>
Processor [1] M 32 N 34 P 32 m 1 n 2 p 2 w 1 s 1<br>
X range of indices: 0 32, Y range of indices: 17 34, Z range of
indices: 0 16<br>
Processor [2] M 32 N 34 P 32 m 1 n 2 p 2 w 1 s 1<br>
X range of indices: 0 32, Y range of indices: 0 17, Z range of
indices: 16 32<br>
Processor [3] M 32 N 34 P 32 m 1 n 2 p 2 w 1 s 1<br>
X range of indices: 0 32, Y range of indices: 17 34, Z range of
indices: 16 32<br>
</p>
</blockquote>
<p>In PETSc 3.8.4 (and later?) the same function call only prints
out:</p>
<blockquote>
<p>DM Object: 4 MPI processes<br>
type: da</p>
</blockquote>
<p>Does the feature to print out the ownership ranges still exist?<br>
I am unable to find it.<br></p></div></blockquote><div>Certainly the latest release prints what you expect:</div><div><br></div>
