If you mean literally 3 scalar laplacians packed in one matrix for some reason
then the one constant vector is fine. Is this a block diagonal matrix with 3

I have changed the architecture of residual calculations in PETSc, in

OK, is this the plan:
1) I should add a residual method to Mat, get rid of PCMGResidualDefault, make
a MatResidualDefault, and have all (yuck) SetUp_MatXXX set this default.
So do we have a consensus? use h->id plus a state thing to test the vector and
the state thing to test the this Mat. I thought there was already a 'state
thing' someplace. But it sounds like you are designing it here.

I have a code that has several concurrent solves (with their own communicators)
and I want to turn off monitors for all but one. My setup code looks something
like this:
call DMSetFromOptions(solver%dalam,ierr)
call DMCompositeAddDM(solver%da,solver%dalam,ierr)
call DMSetFromOptions(solve
I have a SNES solver that runs with a linear operator at times. I use
-ksp_ksponly. The KSPSetOperator seems to get called every solve because the
PC setup code gets called every solve. Should this be happening?

This is happening when the prolongation matrix is repartitioned. The number of
active processors is being reduced. MatGetSubmatrix is called just a few lines
before this with a square matrix, doing the same basic repartitioning. So this

Wow, Barry is the the good cop.

Isn't this paper just doing two level unsmoothed aggregation with a V(0,k)
cycle, where k (and the smoother) is K in the paper?
It looks to me like
I have a SNES solver and use -mat_view ::ascii_matlab.
I do two SNES iterations and get three matrices output. My formJAcobean
explicitly forms AIJ matrices. After the 2nd two matrix printouts I see:
Matrix-free approximation:
err=1.49012e-08 (relative error in function evaluation)

Yes it should be removed, I just deleted the whole section and tested it.
We could

The logic here is messed up. Valid input could result in a non-col
Do you have more of a stack in the error output?
The ML interface has had some additions to make it more consistent with blocked
matrices. Do you block all of your matrices?

I pulled today and did a deep clean but get this error:

This is what I cloned. I just got a debug version working so I'll do a deep
cleaning.

If I nm the .a files I see things like:
_VecNestGetSubVec
But the link errors are for
_vecnestgetsubvec_
It has an extra subscript ? but it is finding other Vec methods.

That did not help:
program main
#include
#include
use petscdm
use petscdmda
use petscsnes
use petsc_kkt_solver_module
use petsc_kkt_solver_moduleinterfaces
! implicit none
And I have this problem also:
