​When coupled, is there some periodic sharing of data? If not, what do we
mean by "coupled"? If so, is there some subset of the data that is
specifically intended to be shared?

I'd have guessed that at some set of timesteps, there would be sharing of
only some of the states ....

If so, wouldn't we need not only "teams" but some what to indicate the
subset of the teams that interact? And some way to limit the interaction to
specific timesteps?​
