Also changed existing MOM6 layouts to explicitly look for non-MARBL configuration
still running some timing experiments to see what layout fits S and XL on derecho
I'm having trouble getting 20 SYPD in MOM6 with MARBL enabled; 25 nodes gives me 19.9 myears / day in the ocean but 18.16 SYPD overall. Increasing to 27 nodes or 30 nodes both slow the model down, possibly due to increased communication or possibly due to the machine being busy? We might want to adjust the XL layout in a future alpha tag.
Until we decide to turn MARBL on by default, the compsets should not change. However, I created a temporary BLT1850_MARBL compset to make it easier to run with MARBL while we do final testing (also, I added an ERI test for that compset so we aren't surprised by anything when we update the compset definitions)
I will update it to leverage git-fleximod, but want to use the more extensive python script as a starting point.
Improve describe_version for git-fleximod
Cesm3.0 add marbl
Noticed that the total core count requested didn't divide evenly over 128-core nodes, so dropped NTASKS_OCN by 48
fix for git worktree issue
