- E3SM/cime_config/machines/config_machines.xml: Contains list of valid compilers (COMPILERS) and environment setup (modules, environment_variables).
- E3SM/cime_config/machines/config_compilers.xml: DEPRECATED. Contains specifications (flags, link flags, exe names) for compilers (gcc, pgi) as well as machine-specific modifications for those compilers. This system can be reactivated by setting CIME_NO_CMAKE_MACRO=1 in your environment.
- E3SM/cime_config/machines/cmake_macros/*: Contains specifications (flags, link flags, exe names) for compilers (gcc, pgi) as well as machine-specific modifications for those compilers. Replaces config_compilers.xml.
- E3SM/cime_config/machines/Depends.$compiler.$machine.cmake: Contains machine/compiler-specific flag changes for specific E3SM component files
- E3SM/cime/scripts/Tools/e3sm_compile_wrap.py: The default compile/link wrapper. It is used to produce timings of all operations
- E3SM/cime/scripts/machines/scripts/*: Python scripts to assist in managing cmake macro files.
- E3SM/components/CMakeLists.txt: The root CMakeLists.txt file for E3SM, mostly just iterates over components and calls functions
- E3SM/components/cmake/cmake_util.cmake: Contains some generally useful functions for cmake
- E3SM/components/cmake/build_mpas_model.cmake: Implements the handoff between E3SM's CMake system to MPAS's Cmake system
E3SM/components/cmake/common_setup.cmake: Cmake setup common to all core components, this is only invoked ones (AFTER mpas is configured)
- E3SM/components/cmake/build_model.cmake: Implements how an individual core component gets configures (involves reading the Filepath and CCSM_cppdefs, globbing files, etc)
- E3SM/components/cmake/modules/*.cmake: Cmake modules for finding packages we depend on
- E3SM/components/cmake/*/CMakeLists.txt: Very thin CMakeLists.txt files for each component type, this is just to ensure each component get it's own build area
- E3SM/components/*/bld/configure: Perl configure script for component, should produce Filepath and CCSM_cppdefs files
- E3SM/components/*/cime_config/buildnml: The buildnml script for component, controls what flags get passed to $component/bld/configure
- E3SM/components/*/cime_config/buildlib: The legacy buildlib driver for the classic deprecated Makefile-based build system
- E3SM/components/*/cime_config/buildlib_cmake: A insertion point for last-minute, component-specific changes before cmake is called. For example, mosart uses this file, not bld/configure, to generate Filepath and CCSM_cppdefs
- E3SM/components/mpas-source/src/CMakeLists.txt: The root CMakeLists.txt for MPAS
- E3SM/components/mpas-source/src/cmake_utils.cmake: Contains some generally useful functions for configuring MPAS
- E3SM/components/mpas-source/src/build_core.cmake: A generic implementation for building MPAS cores
- E3SM/components/mpas-source/src/core_landice/landice.cmake: The CMake definition of the landice core
- E3SM/components/mpas-source/src/core_ocean/ocean.cmake: The CMake definition of the ocean core
- E3SM/components/mpas-source/src/core_seaice/seaice.cmake: The CMake definition of the seaice core
- E3SM/share/buildlib: Python build wrapper scripts for our SHAREDLIB packages. CIME invokes these during the SHAREDLIB build phase.
- $case/Buildconf/*conf: The various build conf dirs for all active components, the Filepath and CCSM_cppdefs files for each component live here
- $case/Macros.cmake: The file that includes the relevant files in cmake_macros. You can modify this locally in your case.
- $case/cmake_macros/*: The files that ultimately sets flags, link flags, etc. You can modify this locally in your case.
- $case/Macros.make: A makefile macro derived from the cmake macros, needed for the sharedlibs that still use Makefile build systems. This is an auto-generated file that you should never edit.
- $case/SourceMods/src.$component/*: Alternative source files to use instead of the ones from the component in your source dir
- $EXEROOT/cmake-bld: The root cmake build/binary directory
- $case/Tools/e3sm_compile_wrap.py: The case-specific compiler wrapper, this will start out as a copy of the e3sm_compile_wrap.py from the repo. Users can customize this one.
