Dear Petsc-Users-List,
I recently upgraded to petsc3.3-p5 from petsc3.2-p7 and the results from my code have changed. I am using superLU with the following options:
-ksp_type preonly -pc_type lu -pc_factor_mat_solver_package superlu_dist
Everything was working with petsc3.2 but now I get totally different answers and the iteration doesn't converge. My build configuration is
./config/configure.py --prefix=${HOME}/Packages --with-fortran=0 --download-superlu_dist=1 --with-x=0 --download-parmetis=1 --download-metis=1 --with-mpi-dir=${HOME}/Packages --with-valgrind-dir=${HOME}/Packages
I am running on OS X 10.8.2 with openmpi-1.6.3.
I have run valgrind on my code and it is clean (except for start-up issues with mpi which occur before my code is entered.)
I'm not very sure how to go about debugging this. What I've tried is to re-install pets-3.2-p7, but now I am having trouble getting that to build:
./config/configure.py --prefix=${HOME}/Packages --with-fortran=0 --download-superlu_dist=1 --with-x=0 --download-parmetis=1 --download-metis=1 --with-mpi-dir=${HOME}/Packages --with-valgrind-dir=${HOME}/Packages

Any ideas what direction to go with this?
Thanks,
