BASICS: What are the directories and files in my case directory?

The following describes many of the files and directories in the $CASEROOT directory.

Buildconf/

is the directory where the buildnml and buildexe component scripts reside and where the input_data_list files are generated by the buildnml scripts.

CaseDocs/

is the directory where copies of the latest namelist/text input files from invoking preview_namelists are placed. These files should not be edited and exist only to help document the case setup and run.

SourceMods/

contains directories for each component where case specific source code modifications can be included. The source files in these directories will always be used in preference to the source code in $CCSMROOT. This feature allows users to modify CESM source code on a case by case basis if that preferable over making modifications in the $CCSMROOT sandbox.

LockedFiles/

is the directory that holds copies of the locked files.

MachinesHist/

is a directory where previous case configurations are stored. In other words, when cesm_setup -clean is run, the current batch run script and env_mach_pes.xml file are copied into this directory, so when cesm_setup is subsequently run, there is an opportunity to review and compare previous setups.

Macros

is the Makefile Macros file for the current configuration. The Makefile is located in the Tools directory and is identical on all machines. The Macros file is a machine and compiler dependent file. This file is locked during the build step.

README.case

provides a summary of the commands used to generate this case.

$CASE.build

is the script that is run interactively to build the CESM model.

$CASE.clean_build

is the script that cleans the CESM build.

$CASE.l_archive

is the script that is submitted to the batch queue to archive CESM data to the long-term archive disk, like an hpss or mass storage system.

$CASE.run

is the script that is submitted to the batch queue to run a CESM job. This script could also be run interactively if resources allow.

check_input_data

is a tool that checks for missing input datasets and provides a capability for exporting them to local disk.

cesm_setup

is the script that is run to generate the $CASE.run script for the target env_mach_pes.xml file and if they have not already been created, the user_nl_xxx files for the target components.

create_production_test

is a tool that generates an exact restart test in a separate directory based on the current case.

env_*.xml files

contain variables used to set up, build, and run CESM.

logs/

is the directory that contains a copy of the component log files from successful case runs.

timing/

is the directory that contains timing output from each successful case run.

xmlchange

is a utility that supports changing xml variables in the $CASEROOT xml files.

$CASEROOT/Tools/

a directory containing many scripts that are used to set up the CESM model as well as run it. Some of particular note are
