- On *Linux*:
    - [Install docker on Linux](https://docs.docker.com/desktop/install/linux-install/)
    - Follow similar steps as *Mac* for starting Docker and verifying the installation

Download the input data in "ngen-data" folder from S3 bucket :

Linux & Mac

    $ mkdir NextGen
    $ cd NextGen
    $ mkdir ngen-data
    $ cd ngen-data
    $ wget --no-parent https://ciroh-ua-ngen-data.s3.us-east-2.amazonaws.com/AWI-001/AWI_03W_113060_001.tar.gz
    $ tar -xf AWI_03W_113060_001.tar.gz 
    $ cd AWI_03W_113060_001

Windows Steps:

    Use browser to download the data from https://ciroh-ua-ngen-data.s3.us-east-2.amazonaws.com/AWI-001/AWI_03W_113060_001.tar.gz
   
    $ mkdir NextGen
    $ cd NextGen
    $ mkdir ngen-data
    $ cd ngen-data
    $ Open browser and download data from here: https://ciroh-ua-ngen-data.s3.us-east-2.amazonaws.com/AWI-001/AWI_03W_113060_001.tar.gz
    and copy the downloaded file to ngen-data folder.
    Use WinRAR to extract the files from the tar bundle.
    $ cd AWI_03W_113060_001

Run NextGen-In-A-Box

Clone CloudInfra repo

Clone the repo using below commands:

$ cd NextGen  
$ git clone https://github.com/AlabamaWaterInstitute/CloudInfra.git

$ cd CloudInfra

Once you are in CloudInfra directory, you should see guide.sh in it. Now, we are ready to run the model using that script.

How to run the model script?

Follow below steps to run guide.sh script

    # Note: Make sure you are in ~/Documents/NextGen/CloudInfra directory
    $ ./guide.sh   
    

Output of the model guide script

What you will see when you run above guide.sh?

  • The script prompts the user to enter the file path for the input data directory where the forcing and config files are stored.

Run the following command based on your OS and copy the path value:

Windows:

C:> cd ~\<path>\NextGen\ngen-data
c:> pwd
and copy the path

Linux/Mac:

$ cd ~/<path>/NextGen/ngen-data
$ pwd
and copy the path

where is the localtion of NextGen folder.

  • The script sets the entered directory as the HOST_DATA_PATH variable and uses it to find all the catchment, nexus, and realization files using the find command.
  • Next, the user is asked whether to run NextGen or exit. If run_NextGen is selected, the script pulls the related image from the awiciroh Dockerhub, based on the local machine's architecture:
For Mac (arm architecture), it pulls awiciroh/ciroh-ngen-image:latest-arm.
For x86 machines, it pulls awiciroh/ciroh-ngen-image:latest-x86.
  • The user is then prompted to select whether they want to run the model in parallel or serial mode.
  • If the user selects parallel mode, the script uses the mpirun command to run the model and generates a partition file for the NGEN model.
  • If the user selects the catchment, nexus, and realization files they want to use.

Example NGEN run command for parallel mode:

mpirun -n 2 /dmod/bin/ngen-parallel 
/ngen/ngen/data/config/catchments.geojson "" 
/ngen/ngen/data/config/nexus.geojson "" 
/ngen/ngen/data/config/awi_simplified_realization.json 
/ngen/partitions_2.json
  • If the user selects serial mode, the script runs the model directly.

Example NGEN run command for serial mode:

/dmod/bin/ngen-serial 
/ngen/ngen/data/config/catchments.geojson "" 
/ngen/ngen/data/config/nexus.geojson "" 
/ngen/ngen/data/config/awi_simplified_realization.json
  • After the model has finished running, the script prompts the user whether they want to continue.
  • If the user selects yes, the script opens an interactive shell. If the user selects no, the script exits.

The output files are copied to the outputs folder in HOST_DATA_PATH.
