GAMG is almost algorithmically invariant but the graph coarsening is not
invariant not deterministic. You should not see much difference in teration
could but a little decay is expected.

Hi Matt/Barry,
I've implemented this for 1D-complex-mpi vec and tested it.
Here is the modified source file ->

Yes - the default preconditioner is block-jacobi - with one block on
each processor.
So when run on 1 proc vs 8 proc - the preconditioner is different
(with 1block for bjacobi vs 8blocks for bjacobi)- hence difference in
convergence.
