But just one instance of DATM? That works?

All prognostic components need to have the same number of instances, but the data components have the flexibility to have a single or multiple instances. This is based on the Section "Multi-instance component functionality" described in https://www2.cesm.ucar.edu/models/cesm1.2/cesm/doc/usersguide/ug.pdf which has the following example:

For an F compset, only atm, lnd, rof are full prognostic components. The ocn is a prescribed data component, cice is a mixed prescribed/prognostic component (ice-coverage is prescribed) and glc and wav are stub components. Lets say we want to run 2 instances of CAM in this experiment. The current implementation of multi-instances will also require you to run 2 instances of CLM, CICE and RTM. However, you have the flexibility to run either 1 or 2 instances of DOCN (we can ignore glc and wav since they do not do anything in this compset).

merged to master.

Note: pm-cpu has yet to report and may not today for this test.
