These variables SHOULD NOT be changed once the model has been built. urrently, these variables are not cached. Note1: users SHOULD NOT modify BUILD_COMPETE below this is done automatically by the scripts.

Base directory for build and run directories. char Case executable root directory. (executable is $EXEROOT/$MODEL.exe, component libraries are in $EXEROOT/lib) This is where the model builds its executable and by default runs the executable. Note that EXEROOT needs to have enough disk space for the experimental configuration requirements. As an example, a model run can produce more than a terabyte of data during a 100-year run, so you should set EXEROOT to scratch or tmp space and frequently back up the data to a long term archiving storage device For a supported machine, EXEROOT is set in $CIMEROOT/machines/config_machines.xml. For a userdefined machine, EXEROOT must explicitly be set it in env_build.xml. char NO_LEAP,GREGORIAN calendar type char mct,nuopc use MCT component interface logical TRUE,FALSE TRUE implies using the ESMF library specified by ESMF_LIBDIR or ESMFMKFILE logical TRUE,FALSE TRUE implies turning on run and compile time debugging Flag to turn on debugging for run time and compile time. If TRUE, compile-time debugging flags are activated that you can use to verify software robustness, such as bounds checking. Important:: On IBM machines, floating point trapping is not activated for production runs (i.e., non-DEBUG), due to performance penalties associated with turning on these flags. logical TRUE,FALSE TRUE implies always build model for openmp capability If FALSE, component libraries are built with OpenMP capability only if the NTHREADS_ setting for that component is greater than 1 in env_mach_pes.xml. If TRUE, the component libraries are always built with OpenMP capability. logical TRUE,FALSE TRUE implies that at least one of the components is built threaded (DO NOT EDIT) logical TRUE,FALSE TRUE implies linking to the PETSc library - set automatically by XXX_USE_PETSC options (do not edit). Flag to turn on linking to the PETSc library. Currently this is used by CLM. This is currently only supported for certain machines. logical TRUE,FALSE TRUE implies linking to the Albany library - set automatically by XXX_USE_ALBANY options (do not edit). Flag to turn on linking to the Albany library. Currently this is used by MALI. Note that Albany is a C++ library, so setting this variable to TRUE will involve the inclusion of C++ code in the MALI executable. This is currently only supported for certain machines. logical TRUE,FALSE TRUE implies linking to the MOAB library logical TRUE,FALSE TRUE implies linking to the trilinos library - set automatically by XXX_USE_TRILINOS options (do not edit) Flag to turn on linking to the trilinos library. Currently this is used by CISM. Note that trilinos is a C++ library, so setting this variable to TRUE will involve the inclusion of C++ code in the model executable. This is currently only supported for certain machines. char Operating system - DO NOT EDIT UNLESS for userdefined machine - ignored once Macros has been created. char Machine compiler (must match one the supported compilers) Set in $CIMEROOT/machines/config_machines.xml for each supported machine. Must be explicitly set in env_build.xml for userdefined machine. char mpi library (must match one of the supported libraries) - ignored once Macros has been created Set in $CIMEROOT/machines/config_machines.xml for each supported machine. Must be explicitly set in env_build.xml for userdefined machine. integer 1,2 PIO library version char PIO configure options, see PIO configure utility for details logical TRUE,FALSE Status output: if TRUE, models have been built successfully. (DO NOT EDIT)> char Status: smp status of previous build, coded string.

(DO NOT EDIT)> char Status: ninst status of current case, coded string (DO NOT EDIT) integer 0,1,2 Status: of prior build. (DO NOT EDIT) logical TRUE,FALSE TRUE implies CLM is built with support for the PETSc library. The Variably Saturated Flow Model (VSFM) solver in CLM uses the PETSc library. In order to use the VSFM solver, CLM must be built with PETSc support and linking to PETSc must occur when building the ACME executable. This occurs if this variable is set to TRUE. Note that is only available on a limited set of machines/compilers. char Provides option(s) for the CLM configure utility. CLM_CONFIG_OPTS are normally set as compset variables (e.g., -bgc cn) and in general should not be modified for supported compsets. It is recommended that if you want to modify this value for your experiment, you should use your own user-defined component sets via using create_newcase with a compset_file argument. This is an advanced flag and should only be used by expert users. char CAM cpp definitions (setup automatically - DO NOT EDIT) char eul,fv,se CAM dynamical core char CAM configure options, see CAM configure utility for details Provides option(s) for the CAM configure utility. CAM_CONFIG_OPTS are normally set as compset variables (e.g., -phys cam4 -chem waccm_ma) and in general should not be modified for supported compsets. It is recommended that if you want to modify this value for your experiment, you should use your own user-defined component sets via using create_newcase with a compset_file argument char CLM cpp definitions (if-any) (setup automatically - DO NOT EDIT) char prognostic,prescribed,thermo_only Option to the CICE configure utility for the -mode argument (default is prognostic) char CICE configure options, see CICE configure utility for details. Provides option(s) for the CLM configure utility. CICE_CONFIG_OPTS are normally set as compset variables (e.g., -ntr_aero 3) and in general should not be modified for supported compsets. It is recommended that if you want to modify this value for your experiment, you should use your own user-defined component sets via using create_newcase with a compset_file argument. This is an advanced flag and should only be used by expert users. logical true,false This is for experts only - if CICE_AUTO_DECOMP is set to false, then can manually set the values of CICE_BLCKX, CICE_BLCKY, CICE_MXBLCKS, CICE_DECOMPTYPE, and CICE_DECOMPSETTING". integer Size of cice block in first horiz dimension (DO NOT EDIT if CICE_AUTO_DECOMP is true). This is for experts only - automatically set if CICE_AUTO_DECOMP is true to set this value, must first set CICE_AUTO_DECOMP to false. integer Size of cice block in second horiz dimension (DO NOT EDIT if CICE_AUTO_DECOMP is true).
