<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a way to set different number of local rows for each processor when using createAIJ with csr option with petsc4py? In petsc documentation it is clearly shown ( set int m) but I couldn’t figure it out with petsc4py.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried the following but it did not work (ploc is the local number of rows, ptot is the total number of rows and it is square sparse matrix)<o:p></o:p></p>

<p class="MsoNormal" style="text-indent:.5in">pA = PETSc.Mat().createAIJ(size=(ploc, ptot, ptot, ptot), csr=(indptr.astype(dtype='int32'), indices.astype(dtype='int32'), data))<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
