Revision 3657e4066889b03de1ae808db02c049a13ccca7d authored by Alan V Di Vittorio on 08 December 2023, 23:14:38 UTC, committed by Alan V Di Vittorio on 08 December 2023, 23:14:38 UTC
The model successfully runs to completion for ZLND with functional CO2 downscaling. The linearly downscaled CO2 data have been verified within the GCAM repo code, but not yet in the fortran ehc code (giac repo). Convergence downscaling has not been verified. Restarts work properly. The gcam namelist has been updated to add several options for convergence downscaling and the gcam co2 passing namelist item has been corrected in name. A shell script has been added to gcam/tools that generates the new input base co2 gridded files. The fortran floating point exception checks are still off because the model still fails due to untrapped GCAM nans if these are on (which usually is only when DEBUG=TRUE). This allows for DEBUG to be set to TRUE and for the model to run. The configuration for the boost library for the ehc/gcam now points to the files in the gcam repo for portability. The xerces library configuration has been removed as it is no longer needed by GCAM. The three repo branches (e3sm, giac, gcam) at this commit work together (at least for ZLND), and thse branches are set in the .gitmodules files.

Energy Exascale Earth System Model (E3SM)
================================================================================
E3SM is a state-of-the-art fully coupled model of the Earth's climate including
important biogeochemical and cryospheric processes. It is intended to address
the most challenging and demanding climate-change research problems and
Department of Energy mission needs while efficiently using DOE Leadership
Computing Facilities.

Quick Start
--------------------------------------------------------------------------------
The [Quick Start](https://e3sm.org/model/running-e3sm/e3sm-quick-start/) page
includes instructions on obtaining the necessary code and input data for model
setup and execution on a supported machine.
Supported Machines
--------------------------------------------------------------------------------
E3SM is a high-performance computing application and generally requires a
capable compute cluster to run a scientifically validated case at a useful
simulation speed.
To run E3SM, it is recommended that you obtain time on a
[Supported Machine](https://e3sm.org/model/running-e3sm/supported-machines/).
Running
