CoupledModelDriver

tests codecov build version license style documentation

CoupledModelDriver generates an overlying job submission framework and configuration directories for NEMS-coupled coastal ocean model ensembles.

pip install coupledmodeldriver

It utilizes NEMSpy to generate NEMS configuration files, shares common configurations between runs, and organizes spinup and mesh partition into separate jobs for dependant submission.

Documentation can be found at https://coupledmodeldriver.readthedocs.io

usage example

1. generate JSON configuration files

initialize_adcirc creates JSON configuration files according to the given parameters. ADCIRC run options that are not exposed by this command, such as runs or gwce_solution_scheme, can be specified by directly modifying the JSON files. The following creates JSON files for coupling (ATMESH + WW3DATA) -> ADCIRC over a small Shinnecock Inlet mesh:

initialize_adcirc \
    --platform HERA \
    --mesh-directory /scratch2/COASTAL/coastal/save/shared/models/meshes/shinnecock/v1.0 \
    --output-directory hera_shinnecock_ike_spinup_tidal_atmesh_ww3data \
    --modeled-start-time 20080823 \
    --modeled-duration 14:06:00:00 \
    --modeled-timestep 00:00:02 \
    --nems-interval 01:00:00 \
    --adcirc-executable /scratch2/COASTAL/coastal/save/shared/repositories/CoastalApp/ALLBIN_INSTALL/NEMS-adcirc-atmesh-ww3data.x \
    --adcirc-processors 40
    --adcprep-executable /scratch2/COASTAL/coastal/save/shared/repositories/CoastalApp/ALLBIN_INSTALL/adcprep \
    --modulefile /scratch2/COASTAL/coastal/save/shared/repositories/CoastalApp/modulefiles/envmodules_intel.hera \
    --forcings tidal,atmesh,ww3data \
    --tidal-source TPXO \
    --tidal-path /scratch2/COASTAL/coastal/save/shared/models/forcings/tides/h_tpxo9.v1.nc \
    --tidal-spinup-duration 12:06:00:00 \
    --atmesh-path /scratch2/COASTAL/coastal/save/shared/models/forcings/shinnecock/ike/wind_atm_fin_ch_time_vec.nc \
    --ww3data-path /scratch2/COASTAL/coastal/save/shared/models/forcings/shinnecock/ike/ww3.Constant.20151214_sxy_ike_date.nc

This will create the directory hera_shinnecock_ike_spinup_tidal_atmesh_ww3data/ with the following JSON configuration files:

📂 hera_shinnecock_ike_spinup_tidal_atmesh_ww3data/
┣ 📜 configure_adcirc.json
┣ 📜 configure_atmesh.json
┣ 📜 configure_modeldriver.json
┣ 📜 configure_nems.json
┣ 📜 configure_slurm.json
┣ 📜 configure_tidal_forcing.json
┗ 📜 configure_ww3data.json

These files contain relevant configuration values for an ADCIRC run. You will likely wish to change these values to alter the resulting run, before generating the actual model configuration. For instance, NEMS connections and the run sequence need to be manually specified in configure_nems.json.

2. generate model configuration files

generate_adcirc generates an ADCIRC run configuration (fort.14, fort.15, etc.) using options read from the JSON configuration files (generated in the previous step).

cd hera_shinnecock_ike_spinup_tidal_atmesh_ww3data
generate_adcirc

The resulting configuration will look like this:

📂 hera_shinnecock_ike_spinup_tidal_atmesh_ww3data/
┣ 📜 configure_adcirc.json
┣ 📜 configure_atmesh.json
┣ 📜 configure_modeldriver.json
┣ 📜 configure_nems.json
┣ 📜 configure_slurm.json
┣ 📜 configure_tidal_forcing.json
┣ 📜 configure_ww3data.json
┣ 📂 spinup/
┃  ┣ 📜 fort.13
┃  ┣ 🔗 fort.14 -> ../fort.14
┃  ┣ 📜 fort.15
┃  ┣ 📜 nems.configure
┃  ┣ 📜 model_configure
┃  ┣ 🔗 atm_namelist.rc -> ./model_configure
┃  ┣ 📜 config.rc
┃  ┣ 📜 setup.job
┃  ┗ 📜 adcirc.job
┣ 📂 runs/
┃  ┗ 📂 unperturbed/
┃    ┣ 📜 fort.13
┃    ┣ 🔗 fort.14 -> ../../fort.14
┃    ┣ 📜 fort.15
┃    ┣ 🔗 fort.67.nc -> ../../spinup/fort.67.nc
┃    ┣ 🔗 fort.68.nc -> ../../spinup/fort.68.nc
┃    ┣ 📜 nems.configure
┃    ┣ 📜 model_configure
┃    ┣ 🔗 atm_namelist.rc -> ./model_configure
┃    ┣ 📜 config.rc
┃    ┣ 📜 setup.job
┃    ┗ 📜 adcirc.job
┣ 📜 fort.14
┣ 📜 cleanup.sh
┗ 📜 run_hera.sh

3. run the model

The previous step will also have generated a script called ./run_hera.sh. You can run it to submit the model run to the Slurm job queue:

./run_hera.sh

The queue will have the following jobs added:

   JOBID CPU NODE DEPENDENCY       NODELIST(REA NAME
20967647 1   1    (null)           (None)       ADCIRC_SETUP_SPINUP
20967648 40  1    afterok:20967647 (Dependency) ADCIRC_COLDSTART_SPINUP
20967649 1   1    (null)           (None)       ADCIRC_SETUP_unperturbed
20967650 42  2    afterok:20967649 (Dependency) ADCIRC_HOTSTART_unperturbed

4. track model progress

check_completion checks the completion status of a running model directory.

cd hera_shinnecock_ike_spinup_tidal_atmesh_ww3data
check_completion
{
    "hera_shinnecock_ike_spinup_tidal_atmesh_ww3data": {
        "spinup": "running - 15%",
        "runs": "not_started - 0%"
    }
}

you can also pass a specific directory (or several directories):

check_completion spinup
{
    "spinup": "running - 27%"
}
cd run_20211027_florence_besttrack_250msubset_quadrature
check_completion runs/*_13
{
    "vortex_4_variable_perturbation_13": "completed - 100.0%",
    "vortex_4_variable_quadrature_13": "not_started - 0%"
}

if a run has an error, you can pass --verbose to see detailed logs:

check_completion spinup
{
    "spinup": "error - 0%"
}
check_completion spinup --verbose
{
    "spinup": {
        "status": "error",
        "progress": "0%",
        "error": {
