[petsc-users] Implementing of a variable block size BILU preconditioner

[Ali Reza Khaz'ali via petsc-users]

Hi,

I want to implement a variable block size BILU preconditioner in PETSc. 
I am wondering if modifying the PCVPBJACOBI preconditioner 
(vpbjacobi.c), to get what I want, is a good idea.

Any help is much appreciated.
