[petsc-users] The parallel preconditioner

Hello there,

I have been confused of the extent of the available preconditioners in PETSc for a while. Here are the lists I got from one slide of a lecture notes saying

Block Jacobi,
Overlapping Additive Schwarz,
ICC, ILU (sequential only)
ILU(K), LU(direct solver, sequential only)

But in some other sources, only LU is highlighted with "sequential only". Which one is correct? I am using MATCreateAIJ to construct my A. Which preconditioner is available to me? By the way, I  tested asm, ilu, icc, and they all failed.
