CoupledModelDriver

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

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.

Supported models and platforms

• models
  • circulation models
    • ADCIRC (uses adcircpy)
  • forcings
    • ATMESH
    • WW3DATA
• platforms
  • local
  • Slurm
    • Hera
    • Stampede2

Usage

Example scripts can be found at examples/<platform>

1. generate JSON configuration files

The following code (examples/nems_adcirc/hera_shinnecock_ike_spinup_tidal_atmesh_ww3data.py) creates a configuration for coupling (ATMESH + WW3DATA) -> ADCIRC on Hera, over a small Shinnecock Inlet mesh:

#! /usr/bin/env python

configuration.write_directory(OUTPUT_DIRECTORY, overwrite=False)

generation_script = NEMSADCIRCGenerationScript()
generation_script.write(OUTPUT_DIRECTORY / 'generate_nems_adcirc.py', overwrite=True)

Alternatively, you may use the command-line interface:

initialize_adcirc --platform HERA --mesh-directory ../../../../models/meshes/hsofs/250m/v1.0 --modeled-start-time 20080823 --modeled-duration 14:06:00:00 --modeled-timestep 00:00:02 --nems-interval 01:00:00 --tidal-spinup-duration 12:06:00:00 --tidal-forcing-source TPXO --tidal-forcing-path /scratch2/COASTAL/coastal/save/shared/models/forcings/tides/h_tpxo9.v1.nc --forcings AtmosphericMeshForcing,WaveWatch3DataForcing --directory hera_shinnecock_ike_spinup_tidal_atmesh_ww3data --generate-script

Either method will create the directory hera_shinnecock_ike_spinup_tidal_atmesh_ww3data/ and generate the following JSON configuration files:

📦 hera_shinnecock_ike_spinup_tidal_atmesh_ww3data/
┣ ✎ configure_modeldriver.json
┣ ✎ configure_adcirc.json
┣ ✎ configure_nems.json
┣ ✎ configure_slurm.json
┣ ✎ configure_tidal_forcing.json
┣ ✎ configure_atmesh.json
┣ ✎ configure_ww3data.json
┗  ▶ generate_nems_adcirc.py

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.

2. generate model configuration files

Run the following command to read the JSON configuration and generate the ADCIRC run configuration:

generate_adcirc

The resulting configuration will have the following structure:

📦 hera_shinnecock_ike_spinup_tidal_atmesh_ww3data/
┣ ✎ configure_modeldriver.json
┣ ✎ configure_adcirc.json
┣ ✎ configure_nems.json

3. run the model

Run the following to submit the model run to the Slurm job queue:

sh run_hera.sh

The queue will have the following jobs added:
