[petsc-users] Red-black block Jacobi in PETSc?

[Ben Yee]

Hi,

For the smoother in PCMG, I want to use a red-black block Jacobi smoother.
Is this available with the existing PETSc options?  If so, how do I
designate which blocks are red and which are black?

If it is not possible, what would be the best way to implement this?  Would
I use KSPRICHARDSON+PCSHELL?

Thanks!
