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

It utilizes [`nemspy`](https://pypi.org/project/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`](https://pypi.org/project/adcircpy))
    - forcings
        - ATMESH
        - WW3DATA
- **platforms**
    - local
    - Slurm
        - Hera
        - Stampede2

## Usage

Example scripts can be found at `examples/<platform>`

### 1. generate configuration directory

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

```python
#! /usr/bin/env python

from datetime import datetime, timedelta
from pathlib import Path

from adcircpy import Tides
from adcircpy.forcing.tides.tides import TidalSource
from adcircpy.forcing.waves.ww3 import WaveWatch3DataForcing
from adcircpy.forcing.winds.atmesh import AtmosphericMeshForcing

from coupledmodeldriver.adcirc.nems_adcirc import (
    ADCIRCCoupledRunConfiguration,
    generate_nems_adcirc_configuration,
)
from coupledmodeldriver.platforms import Platform

# paths to compiled `NEMS.x` and `adcprep`
NEMS_EXECUTABLE = '/scratch2/COASTAL/coastal/save/shared/repositories/ADC-WW3-NWM-NEMS/ALLBIN_INSTALL/NEMS-adcirc_atmesh_ww3data.x'
ADCPREP_EXECUTABLE = '/scratch2/COASTAL/coastal/save/shared/repositories/ADC-WW3-NWM-NEMS/ALLBIN_INSTALL/adcprep'

# directory containing input ADCIRC mesh nodes (`fort.14`) and (optionally) mesh values (`fort.13`)
MESH_DIRECTORY = (
        Path('/scratch2/COASTAL/coastal/save/shared/models') / 'meshes' / 'shinnecock' / 'grid_v1'
)

# directory containing input atmospheric mesh forcings (`wind_atm_fin_ch_time_vec.nc`) and WaveWatch III forcings (`ww3.Constant.20151214_sxy_ike_date.nc`)
FORCINGS_DIRECTORY = (
        Path('/scratch2/COASTAL/coastal/save/shared/models') / 'forcings' / 'shinnecock' / 'ike'
)

# directory to which to write configuration
OUTPUT_DIRECTORY = (
        Path(__file__).parent.parent / 'data' / 'configuration' / 'hera_shinnecock_ike'
)

HAMTIDE_DIRECTORY = '/scratch2/COASTAL/coastal/save/shared/models/forcings/tides/hamtide'
TPXO_FILENAME = '/scratch2/COASTAL/coastal/save/shared/models/forcings/tides/h_tpxo9.v1.nc'

platform = Platform.HERA
adcirc_processors = 11
modeled_start_time = datetime(2008, 8, 23)
modeled_duration = timedelta(days=14.5)
modeled_timestep = timedelta(seconds=2)
tidal_spinup_duration = timedelta(days=12.5)
nems_interval = timedelta(hours=1)
job_duration = timedelta(hours=6)

# dictionary defining runs with ADCIRC value perturbations - in this case, a single run with no perturbation
runs = {f'test_case_1': (None, None)}

# describe connections between coupled components
nems_connections = ['ATM -> OCN', 'WAV -> OCN']
nems_mediations = None
nems_sequence = [
    'ATM -> OCN',
    'WAV -> OCN',
    'ATM',
    'WAV',
    'OCN',
]

slurm_email_address = 'example@email.gov'

# initialize `adcircpy` forcing objects
tidal_forcing = Tides(tidal_source=TidalSource.HAMTIDE, resource=HAMTIDE_DIRECTORY)
tidal_forcing.use_all()
wind_forcing = AtmosphericMeshForcing(
    filename=FORCINGS_DIRECTORY / 'wind_atm_fin_ch_time_vec.nc',
    nws=17,
    interval_seconds=3600,
)
wave_forcing = WaveWatch3DataForcing(
    filename=FORCINGS_DIRECTORY / 'ww3.Constant.20151214_sxy_ike_date.nc',
    nrs=5,
    interval_seconds=3600,
)
forcings = [tidal_forcing, wind_forcing, wave_forcing]

configuration = ADCIRCCoupledRunConfiguration(
    fort13=MESH_DIRECTORY / 'fort.13',
    fort14=MESH_DIRECTORY / 'fort.14',
    modeled_start_time=modeled_start_time,
    modeled_end_time=modeled_start_time + modeled_duration,
    modeled_timestep=modeled_timestep,
    nems_interval=nems_interval,
    nems_connections=nems_connections,
    nems_mediations=nems_mediations,
    nems_sequence=nems_sequence,
    tidal_spinup_duration=tidal_spinup_duration,
    platform=platform,
    runs=runs,
    forcings=forcings,
    adcirc_processors=adcirc_processors,
    slurm_partition=None,
    slurm_job_duration=job_duration,
    slurm_email_address=slurm_email_address,
    nems_executable=None,
    adcprep_executable=None,
    source_filename=None,
)

configuration.write_directory(OUTPUT_DIRECTORY, overwrite=True)
generate_nems_adcirc_configuration(OUTPUT_DIRECTORY, overwrite=True)
```

This code will generate a directory `hera_shinnecock_ike/` with the following structure:

```
📦 hera_shinnecock_ike/
┣ 📂 coldstart/
┃  ┣ 📜 fort.13
┃  ┣ 🔗 fort.14 -> ../fort.14
┃  ┗ 📜 fort.15
┣ 📂 runs/
┃  ┗ 📂 test_case_1/
┃    ┣ 📜 fort.13
┃    ┣ 🔗 fort.14 -> ../../fort.14

┣ 📜 nems.configure.coldstart
┣ 📜 nems.configure.hotstart
┣ 📜 config.rc.coldstart
┣ 📜 config.rc.hotstart
┣ 📜 model_configure.coldstart
┣ 📜 model_configure.hotstart
┣ 📜 fort.14
┣ 📜 job_adcprep_hera.job

┣ 📜 job_nems_adcirc_hera.job.hotstart
┣ 📜 setup.sh.coldstart
┣ 📜 setup.sh.hotstart
┣ 📜 setup_hera.sh
┗ 📜 run_hera.sh
```

_**Note:** the required NEMS configuration files (`nems.configure`, `model_configure`) do not yet exist in the run
directories (`coldstart/`, `runs/test_case_1/`). These will be populated in the next step._

### 2. run job submission script `run_<platform>.sh`

Run `run_hera.sh`:

```bash
sh run_hera.sh
``` 

This will first create symbolic links to populate configuration directories (by calling `setup_hera.sh`),

```

and then submit the requested jobs to the queue:

```bash
squeue -u $USER -o "%.8i %.21j %.4C %.4D %.31E %.20V %.20S %.20e"
```
