Parallel regions

What do we think about describing the example code more, e.g. diagrams or more background text? Is it worth the vertical space?
In the exercise solution, we should illustrate clearer the bullet list and refer to parts clearer (line numbers or code exerts). What I mean is that we should include some brief reason why that aspect of the code can be parallelised.

Write a Parallel Function Thinking About a Single Rank

I'm not really sure what the text in this section is trying to convey.
We may need more text here to help set the scene more. But that depends on how much detail we make in the earlier episode about splitting work (episode 3, I think).

Other comments

I wonder if we could move some of this content into an earlier episode (maybe 3?) or into its own episode, and have the code examples/exercises work as a long guided exercise where we walk the learner through porting a serial code? Sort of like a "now you've seen this, put it to use" episode.
