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 <http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/PC/PCHYPRE.html#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
