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

Look what the manual says on ICC:


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

And on ILU:


"Notes: Only implemented for some matrix formats. (for parallel see 
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?
