I am reading your messages, all right, but I also read PETSc's errors and manuals.

Look what the manual says on ICC:

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/PC/PCICC.html

"Notes: Only implemented for some matrix formats. Not implemented in parallel."

And on ILU:

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/PC/PCILU.html

"Notes: Only implemented for some matrix formats. (for parallel see PCHYPRE for hypre's ILU)"

So Matt, if I understand your answer correctly, one should use PCASM to get ILU in parallel, right? What if I want IC?

Thanks,

Bojan
