I’m trying to recreate a control simulation on Derecho that originally was run on Cheyenne, using CESM2.2.0 with the DOCN-SOM. I was able to successfully build and run CESM2.2.0 without any errors, but the monthly output is quite different between the simulation on Derecho versus the simulation on Cheyenne. For example, the discrepancy in TREFHT exceeds 5 K in some regions (see below for a plot of RMSE over the first 20 years).
I’ve checked my setup multiple times to make sure the CESM components, compset, restart files and reference date for the branch, namelists, parameter files, and slab ocean forcing are identical between the two simulations. I've included my run script and output from ./describe_version in the following files. Is it possible that the this difference could be related to changing from Cheyenne to Derecho? Any help or insight would be appreciated!
