I really don't know about threading and Trilinos... there have been some investigations on whether or not it's a good idea... but I haven't seen a MPI+SMP solver come out of any of those investigations. A lot of people (including myself) are still skeptical that it's even a good idea. I personally think that the complexity involved in creating MPISMP software outweighs any potential gains. MPI software is hard to write... and so is SMP.... put the two together and you are just asking for trouble. But, I am also personally interested in looking at these issues. It is clear that machines are headed in this direction... but I still haven't had anyone show me that software written this way would provide dramatic enough speed up to justify the complexity of the software...
