<div dir="ltr">Hi,
<div><br>
</div>
<div>I'm solving a large sparse linear system in parallel and I am using PETSc with MUMPS. I am trying to test different options, like the ordering of the matrix. Everything works if I use the <span style="box-sizing:border-box"><span style="box-sizing:border-box"><font style="color: rgb(0, 0, 0);"><i>-mat_mumps_icntl_7
2 </i>or<i> </i></font></span></span><span style="box-sizing:border-box"><span style="box-sizing:border-box"><font style="color: rgb(0, 0, 0);"><i>-mat_mumps_icntl_7 0 </i></font></span></span>options<i style="color: rgb(0, 0, 0);"> </i><span style="color: rgb(0, 0, 0);">(with
the first one, AMF, performing better than AMD), however when I test METIS </span><span style="color: rgb(0, 0, 0);"><i>-mat_mumps_icntl_7</i><span class="x_gmail-Apple-converted-space"><i> 5
</i>I get an error (reported at the end of the email).</span></span></div>
<div><span style="color: rgb(0, 0, 0);"><span class="x_gmail-Apple-converted-space"><br>
</span></span></div>
<div>I have configured PETSc with the following options: </div>
<div><br>
</div>
<div>--with-cc=mpiicc --with-cxx=mpiicpc --with-fc=mpiifort --with-scalar-type=complex --with-debugging=0 --with-precision=single --download-mumps --download-scalapack --download-parmetis --download-metis<br>
</div>
<div><br>
</div>
<div>and the installation didn't give any problems.</div>
<div><br>
</div>
<div>Could you help me understand why metis is not working? </div>
<div><br>
</div>
<div>Thank you in advance,</div>
<div>Victoria </div>
