Running the ACME model requires a layout for which model cores are assigned to handle which model components called the PE layout. There are currently only a few people who know how to do this and there is no documentation of the process. This is a huge bottleneck which makes running on a new machine or coming up with an efficient layout for a new compset slow. The goal of this page is to provide the info needed for anyone on the project to create their own PE layouts (or at least know when their layout is bad).

To Do: Include PE layout for this case. (note: blue box on right labeled ATM is actually the ocean)
Rules for choosing a PE layout:
