Do we really want to vary PE layouts based on atmospheric grid?

[mnlevy1981]

On my MARBL branch, I ran into an issue with getting unexpected PE layouts because I had modified the <grid name="a%T62.+oi%tx0.66v1"> section of config_pes.xml but hadn't added support for MOM6%MARBL compsets in the <grid name="a%TL319.+oi%tx0.66v1"> section... but it strikes me as odd that we would use different layouts for those two grids. In fact, it looks like these two sections are set up to give identical layouts*. Should they be combined into a single <grid name="oi%tx0.66v1"> section?

* I might have gotten a little lost going back and forth between the two sections, but if I'm reading the file right then on cheyenne MOM gets 864 tasks in all four cases (T62 + C compset, T62 + G compset, TL319 + C compset, TL319 + G compset); the rest of the components share 72 tasks for C compsets or 108 tasks for G compsets, regardless of atm grid.

Should they be combined into a single section?

I agree.
