Quickstart

Tip

build_tsmp2.sh is a lightweight shell-script calling the CMake-based build-system. During execution of build_tsmp2.sh, the executed CMake-command is printed out. For advanced build use-cases, users can modify the outputed CMake command or directly head over to Building TSMP2 with CMake.

1. Clone this repository.

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

2. Build model components with TSMP2 framework

To build a model component one need to activate the component model --<COMP>. The options are not case-sensitive and do not need to be in an specific order.

Note

The component models (git submodules) are cloned during the execution of build_tsmp2.sh. If the component model (models/<COMP>) are already exists, the user is asked if the folder should be overwritten or not. If you do want to use the default model component source codes, one can use the option --<COMP_SRC>.

# to see options
./build_tsmp2.sh --help

# ICON-eCLM-ParFlow
./build_tsmp2.sh --ICON --eCLM --PARFLOW

# eCLM-ParFlow
./build_tsmp2.sh --eCLM --PARFLOW

# ICON-eCLM
./build_tsmp2.sh --ICON --eCLM

# eCLM-PDAF
./build_tsmp2.sh --eCLM --PDAF

# ICON (with source code)
./build_tsmp2.sh --ICON --ICON_SRC ${ICON_SRC}

Building TSMP2 with CMake

Note

For experienced users.

1. Clone this repository.

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

2. Load the environment variables required for the build.

source env/jsc.2023_Intel.sh

3. 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="./run/${SYSTEMNAME^^}_${MODEL_ID}"

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

4. Download the OASIS3-MCT coupling library and the component models that you wish to use. Then save the full path to each model source code to <model-name>_SRC.

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

# eCLM
git clone 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 -b v3.12.0 https://github.com/parflow/parflow.git models/parflow
PARFLOW_SRC=`realpath models/parflow`

# ParFlow (PDAF-patched)
git clone -b v3.12.0-tsmp 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`

5. 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.

      -DPARFLOW=ON                            \
      -DPDAF=ON

6. 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
