Yes, I use this one. I do specify serial partitioning. Basically all parameters are the same, but mumps from petsc just hangs. I work with ldlt factorization. ----- Reply message ----- From: "Sean Farley" <[email protected]> To: "For users of the development version of PETSc" <[email protected]> Subject: [petsc-dev] Problem with MUMPS+metis Date: Mon, Feb 20, 2012 20:42 Which version are you using? The only version of metis supported officially by mumps is metis 4.0.3 which contains METIS_WND and was removed in favor of more arguments to METIS_ND. See my patch submitted here: https://listes.ens-lyon.fr/sympa/arc/mumps-users/2011-11/msg00027.html Search on their mailing list indicates others were successful in linking serially. Did you specify the option for mumps to use serial partitioning (through petsc options), out of curiosity?
