Michael,
We have support of MatCreateRedundantMatrix for dense matrices. For
example, petsc/src/mat/examples/tests/ex9.c:
mpiexec -n 4 ./ex9 -mat_type dense -view_mat -nsubcomms 2

This is easy thanks to the additional debugging I added recently. Your
install of MKL does not have CPardiso support. When you install MKL you have to
make sure you select the "extra" cluster option, otherwise it doesn't install
some of the library. I only learned this myself recently
Dear Petsc developers,
I found that MatCreateRedundantMatrix does not support dense matrices.
This causes the following problem: I cannot use CISS eigensolver from
SLEPC with dense matrices with parallelization over quadrature points.
Is it possible for you to add this support?
Thank you,

Mark,
Good point. This has been a big headache forever
Note that this has been "fixed" in the master version of PETSc and will
be in its next release. If you use --download-parmetis in the

I might have missed something earlier in the thread, but parmetis has a
dependency on the machine's glibc srand, and it can (and does) create
different partitions with different srand versions. The same mesh on the

Thanks for your suggestion, Matthew. I will certainly look into DMForest for
refining of my base DMPlex dm.

On Wed,
I want to implement block-based AMR, which turns my base conformal mesh to
non-conformal. My question is how DMPlex renders a mesh that it cannot support
non-conformal meshes. If DMPlex does not work, I will try to use DMForest.

If DMPlex does not support, I may need to use PARAMESH or CHOMBO. Is there any
way that we can construct non-conformal layout for DM in petsc?

I'm puzzled. It sounds like you are doing non-conforming AMR (structured
block AMR), but Plex does not support that.
