Why is config/PETSc/FEM.py where it is. It isn't configure stuff is it? Can
it be removed or moved to somewhere proper?
What about ./config/BuildSystem/install.old Can that be removed?
Thanks

Suggestions for improvements for the checks?

e matrix on preselected vertices during
MatAssemblyBegin/End? Note that this will imply that standard
Neumann-Neumann methods will not work (they need the unassembled matrix to
solve for the local Schur complements).

Hi,
It looks like when VecWAXPY is called with alpha=Nan,
PetscValidLogicalCollectiveScalar causes the message "Scalar value must be same
on all processes, argument # 2" to be printed. This is a bit misleading, and
confusing when running on only 1 processor.
Is this something worth fixing?
Bl
have that info tomorrow.

I suppose so. How does one do that?

I've got a consistent segv on the Cray at NERSC with 64K cores. No problems
with smaller jobs.
It seems to happen in here:
/* Done after init due to a bug in MPICH-GM? */
ierr = PetscErrorPrintfInitialize();CHKERRQ(ierr);
I can keep diving in, but anyone have any ideas on this?

I'm not too concerned about that since I consider the classic N-N and
original FETI methods to be rather special-purpose compared to the newer
generation. I would like to limit the number of copies of a matrix to
control peak memory usage.
