Is there an example of an OpenMDAO optimization where each iteration of the optimization is designed to run in parallel? The examples I saw seemed focused on the design-of-experiment drivers.

could you clarify a bit? Do you mean, 10 processes to the root and letting it split them up to the various components?

@JustinGray For example, we have a wind farm model where we would like to run each directional case in parallel to calculate the annual energy production. I am curious about an example where the parallelization is split between groups, but my question is about implementing a group meant to run in parallel within an optimizer, like the wind farm example.

Once you get into parallelism within the model, there are potentially many many different ways to split up a problem. However, the simplest case, and the one that is likely the most relevant to something like running multiple directional cases at the same time is just to use a multi-point like setup. This is done with a parallel group, as shown in the multi-point doc.
