PETSc can very well increase the limit to anything you consider sensible,
as long as the agreed limit is somehow enforced, which is what Stefano just
implemented.

OK, so... your point it that what looks like "setup"
e proper way to
do it, IMHO. This way is the one that gives maximum flexibility to power
users/developers, because some times developers may want to configure
objects with some parameters, and do a SetUp() without calling
SetFromOptions() to prevent users to mess up with the parameters the

MatProductSetFromOptions() is not really setting any options. It looks like
the correct name for this API is MatProductSetUp(). In any case, it looks
like both SetFromOptions() and SetUp() should be provided.

Barry, you made the distinction MatSetOperation() vs. MatShellSetOperation().
1) MatSetOperation() is misplaced, it should go somewhere in
src/mat/interface/matrix.c
2) We should add MatGetOperation(), right? Should it just return the
routine set in mat-ops? Are you ok with this?

add `-xxx_exclude <dmts,tsadapt,tstrajectory>` for
fine-grained deactivation.
Option 3: We implement both option 1 and option 2.
So, Barry, what's your preference? The quickest one is just (1) but
the others are also rather trivial to implement.

We have that (I mean, each PETSc typedef). What we are somehow missing
is the mapping plain C 'int' -> MPI_INT. That's important for binary
I/O with non-PETSc formats (e.g. GMSH).

If you don't like and have a better naming convention to suggest,
please let me know.

The only concern I have about PetscPartitioner is that the API depends
on DM (PetscPartitionerPartition_ routines). Maybe
PetscPartitioner should eventually move to became more agnostic, and
that way it can be used to partition mat
