Can you set:<br><br>-mat_mumps_icntl_4 1<br><br>And send mumps output?<br>Also do you use lu or ilu? How large is your matrix?<br><br>Regards,<br>Alexander<br><br><div id="htc_header" style="">----- Reply message -----<br>From: "Wen Jiang" <jiangwen84@gmail.com><br>To: <petsc-users@mcs.anl.gov><br>Subject: [petsc-users] mumps get stuck with parmetis<br>Date: Tue, Apr 24, 2012 19:43<br><br></div><br>Hi,<br><br>My code will hang at the solving stage when I use mumps with the runtime option -mat_mumps_icntl_28 2 -mat_mumps_icntl_29 2. If I remove these two options, my code works fine. I am using PETSc 3.2 and configure it with <span style="color:rgb(255,0,0)"><span style="color:rgb(0,0,0)">--download-mumps=1 and --download-parmetis=1. Could anyone give me any hints? Thanks.<br>
