[petsc-users] coloring algorithms

[Kong, Fande]

Hi All,

I was wondering if the coloring approaches listed online are working? Which
ones are in parallel, and which ones are in sequential?

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Mat/MatColoringType.html#MatColoringType

If the coloring is in parallel, can it be used with the finite difference
to compute the Jacobian? Any limitations?

Fande,
