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>
<br>Regards,<br>Wen </span><br></span>
