Thanks Dave for your time and this detailed reply.
My implementation is old and should probably be updated.
I will read your email carefully and I come back to you with a better
implementation.
Thanks,

Dear Loic,
I can confirm that PCTELESCOPE works nicely when using
KSPSetComputeOperators.
Here is an example
petsc-3.17.1/src/ksp/ksp/tutorials $ mpiexec -n 4 ./ex29 -pc_type mg
-pc_mg_levels 2 -ksp_view -mg_coarse_pc_type telescope
-mg_coarse_pc_telescope_reduction_factor 4 -da_grid_x 65
Python users including myself would love NaN since NaN is the default missing
value marker for reasons of computational speed and convenience. For example,
if you load these values into pandas, no extra code is needed to handle them.
Other choices such as N/A would require some extra work for
Oh, this is not hard:
/* /\* Put NaN into the time for all events that may not be time
accurately since they may happen asynchronously on the GPU *\/ */
/* #if defined(PETSC_HAVE_DEVICE) */
/* if (!PetscLogGpuTimeFlag && petsc_gflops > 0) { */

Ah - by state Matt and I mean any auxiliary data stored in the user context
passed to KSPSetComputeOperators which is required to define your operator
and is distributed. For example, a
Hi Dave,
could you explain what you mean by state ?

Hi Loic,
Can you confirm if your problem has stored state which needs to be
