Building TSMP2 with CMake

Building TSMP2 with CMake#

Note

For experienced users. The result of the following commands may be different from the Quickstart above, most notably because the branches/commits in the git clone commands are not kept in sync with those in the build_tsmp2.sh script. The Quickstart is the tested and supported method.

Clone this repository.

git clone https://github.com/HPSCTerrSys/TSMP2.git
export TSMP2_DIR=$(realpath TSMP2)
cd $TSMP2_DIR

Load the environment variables required for the build.

source env/jsc.2024_Intel.sh

Specify build and install directories.

# Name of the coupled model (e.g. ICON-eCLM, CLM3.5-COSMO-ParFlow, CLM3.5-ParFlow, CLM3.5-ParFlow-PDAF)
MODEL_ID="ICON-eCLM-ParFlow"

# Build artifacts will be generated in this folder. It can be deleted after build.
BUILD_DIR="./bld/${SYSTEMNAME^^}_${MODEL_ID}"

# Model executables and libraries will be installed here
INSTALL_DIR="./bin/${SYSTEMNAME^^}_${MODEL_ID}"

# Create build and install directories
mkdir -p ${BUILD_DIR} ${INSTALL_DIR}

Download the OASIS3-MCT coupling library and the component models you wish to use. You can check out the supported submodule commits using

# eCLM
git submodule update --init -- models/eCLM

# ICON
git submodule update --init -- models/icon

# ParFlow
git submodule update --init -- models/parflow

# ParFlow (PDAF-patched)
git submodule update --init -- models/parflow_pdaf

# CLM3.5
git submodule update --init -- models/CLM3.5

# COSMO5.01
git submodule update --init -- models/cosmo5.01_fresh

# OASIS3-MCT (required for coupled models)
git submodule update --init -- models/oasis3-mct

# PDAF
git submodule update --init -- models/pdaf

If you wish to use alternative (possibly unsupported) commits of component models, clone them explicitly. Then save the full path to each model source code to <model-name>_SRC. Examples are given below:

## NOTE: Download only the component models that you need! ##

# eCLM
git clone -b beta-0.2 https://github.com/HPSCTerrSys/eCLM.git models/eCLM
eCLM_SRC=`realpath models/eCLM`

# ICON
git clone https://icg4geo.icg.kfa-juelich.de/spoll/icon2.6.4_oascoup.git models/icon
ICON_SRC=`realpath models/icon`

# ParFlow
git clone https://github.com/parflow/parflow.git models/parflow
PARFLOW_SRC=`realpath models/parflow`

# ParFlow (PDAF-patched)
git clone -b v3.13.0-pdaf https://github.com/HPSCTerrSys/parflow models/parflow_pdaf
PARFLOW_SRC=`realpath models/parflow_pdaf`

# CLM3.5
git clone -b tsmp-patches-v0.1 https://github.com/HPSCTerrSys/CLM3.5.git models/CLM3.5
CLM35_SRC=`realpath models/CLM3.5`

# COSMO5.01
git clone -b tsmp-oasis https://icg4geo.icg.kfa-juelich.de/ModelSystems/tsmp_src/cosmo5.01_fresh.git models/cosmo5.01_fresh
COSMO_SRC=`realpath models/cosmo5.01_fresh`

# OASIS3-MCT (required for coupled models)
git clone -b tsmp-patches-v0.1 https://icg4geo.icg.kfa-juelich.de/ExternalReposPublic/oasis3-mct models/oasis3-mct
OASIS_SRC=`realpath models/oasis3-mct`

# PDAF
git clone -b PDAF_V2.2.1-tsmp https://github.com/HPSCTerrSys/pdaf.git models/pdaf
PDAF_SRC=`realpath models/pdaf`

Run CMake configure step for the model combination that you wish to build. The examples below show different CMake configure commands for each model combination.

#
#  The component source is searched in models/component by default but there is also the possibility to choose the path to the source code of components with -D<COMP>_SRC=${<COMP>_SRC}. OASIS is taken by default when coupled models are chosen.

Build and install the models.

cmake --build ${BUILD_DIR}
cmake --install ${BUILD_DIR}

Resuming a failed build#

When the build gets interrupted or fails for some reason, it can be resumed by simply running Step 6:

cmake --build ${BUILD_DIR}
cmake --install ${BUILD_DIR}

Note that this works only if the required environment variables are already set. If you are resuming the build from a fresh terminal session, first you need to run source env/jsc.2023_Intel.sh (Step 2), specify BUILD_DIR (Step 3) and set <model-name>_SRC (Step 4) before you can run Step 6.

Rebuilding specific component models#

TSMP2 can rebuild a specific component model via the cmake --build ${BUILD_DIR} --target ${MODEL} command. This may be useful when you need to recompile a component model that has been modified or updated.

# Rebuilding examples

cmake --build ${BUILD_DIR} --target eCLM && cmake --install ${BUILD_DIR}                  # Rebuilds eCLM
cmake --build ${BUILD_DIR} --target ICON && cmake --install ${BUILD_DIR}                  # Rebuilds ICON
cmake --build ${BUILD_DIR} --clean-first --target ParFlow && cmake --install ${BUILD_DIR} # Does a clean rebuild of ParFlow

Only component models specified during CMake configure step (see Step 5) can be rebuilt. For instance, if you configured TSMP2 to build eCLM-ParFlow, then rebuilding ICON would of course be not possible.

The list below shows all component models supported by TSMP2. To rebuild a component model(s), run one or more commands below, wait until the build succeeds, then finally run cmake --install ${BUILD_DIR} so that the generated libraries and executables are copied to ${INSTALL_DIR}.

cmake --build ${BUILD_DIR} --target eCLM
cmake --build ${BUILD_DIR} --target ParFlow
cmake --build ${BUILD_DIR} --target ICON
cmake --build ${BUILD_DIR} --target OASIS3_MCT
cmake --build ${BUILD_DIR} --target CLM3_5
cmake --build ${BUILD_DIR} --target COSMO5_1
