Harry,
AztecOO expects option 1. The precise answer is that the map of X must match the domain map of A and the map of B must match the range map of A.

When solving
AX =b
with Aztec00, what type of Epetra_MultiVector objects do you have to feed into the Azcte00 constructor?
1 Can you feed in X and B objects whose Epetra_Maps objects consist of just owned elements?
2 Can you feed in X and B objects whose Epetra_Maps consist of just owned and "ghost" elements? i.e., ghost elements are elements which are needed to complete the columns of A.
3 Can you feed in X which consists of elements and ghost elements and B which consists of just owned elements.
The question comes about because I didn't see this answered in the doxygen documentation for Aztec00. And, I'm getting some squirrelish behavior that I can't seem to track down.
Thanks in advance,
Harry Moffat
