This fork of CIME (main README below) has been made by ICCS to facilitate the use of the FTorch library (for coupling PyTorch machine learning models to Fortran codes) from within CESM (the Community Earth System Model).
It is based on the maint-5.6 branch which is used to support CESM 2.
To use in CESM, first obtain a copy of CESM as described here
and then modify the Externals.cfg to point at this repository and branch instead:
[cime]
branch = ftorch_forpy_cime
protocol = git
repo_url = https://github.com/Cambridge-ICCS/cime_je
local_path = cime
required = True
You will also need to have a copy of libtorch.
On Derecho this can be loaded with:
module load libtorch/2.1.2
You will then need to build the FTorch library locally on your system as described here.
Finally Modify scripts/Tools/Makefile line 567 to set the environment variable
FTORCH_LOC to the location of the FTorch library on your system.
You can then proceed to write Fortran code using FTorch and build CESM as normal.
Common Infrastructure for Modeling the Earth
CIME, pronounced “SEAM”, contains the support scripts (configure, build, run, test), data models, essential utility libraries, a “main” and other tools that are needed to build a single-executable coupled Earth System Model. CIME is available in a stand-alone package that can be compiled and tested without active prognostic components but is typically included in the source of a climate model. CIME does not contain: any active components, any intra-component coupling capability (such as atmosphere physics-dynamics coupling).
cime (pronounced: seem) is currently used by the Community Earth System Model (CESM) and the Energy Exascale Earth System Model (E3SM).
