Can you add -snes_linesearch_monitor -sub_snes_linesearch_monitor
-ksp_converged_reason and send the output??

It is unlikely that the true number of colors is much less than 230 so I
don't think you can save by reducing the number of colors more.
Are you using IS_COLORING_LOCAL it eliminates much parallel communication so
you would definitely benefit by using this, depending on how your
Hello,
I have used the -mat_coloring_view and -mat_fd_coloring_view flags as you
suggested and it turns out that the coloring used was MATCOLORINGSL.
I have also tried other methods and obtained the following numbers of function
evaluations per Jacobian building:
- MATCOLORINGJP : 593
-
