the two to synchronize and exchange data. The models have differing

We've been playing with barrier to help.
I'm not sure I understand -- "help" meaning what?
If you're exchanging data at the end of an iteration, then you
effectively have a synchronization anyway -- no need for an extra
barrier synchronization.
