Thanks a lot Barry, this was very useful to know. I now see: "Using ParMETIS for parallel ordering." Not that it speeds the ordering up very much... ;) > I apologize that the options are organized in such a silly way but that is > how MUMPS is organized. I suggest to add the above two options to http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Mat/MATSOLVERMUMPS.html or just obsolete the list of options, only providing a cross link to MatMumpsSetIcntl() and a reference to the MUMPS User Guide.
