Test Your Inductiva Setup

Test your Inductiva.AI setup by running a quick COAWST simulation in the cloud before scaling up to advanced weather and climate simulations.

Before diving into tutorials and benchmarks, let's ensure that your Inductiva Python package is properly set up. To confirm everything is working as expected, simply run a quick COAWST simulation — it only takes a few seconds!

Step 1: Copy and Run the Code

Copy the code below and save it as example.py on your Desktop (or in your preferred directory).

"""COAWST example."""
import inductiva

# Instantiate machine group
cloud_machine = inductiva.resources.MachineGroup( \
    provider="GCP",
    machine_type="c2d-highcpu-4",
    spot=True)

# Download the input files into a folder
input_dir = inductiva.utils.download_from_url(
    "https://storage.googleapis.com/inductiva-api-demo-files/"
    "coawst-input-example.zip",
    unzip=True)

# Initialize the Simulator
coawst = inductiva.simulators.COAWST( \
    version="3.8")

# Run simulation
task = coawst.run( \
    input_dir=input_dir,
    sim_config_filename="ocean_ducknc.in",
    build_coawst_script="build_coawst.sh",
    n_vcpus=4,
    use_hwthread=True,
    on=cloud_machine)

# Wait for the simulation to finish and download the results
task.wait()
cloud_machine.terminate()

task.download_outputs()

task.print_summary()

Open your command line, then navigate to the Desktop by running:

cd ~/Desktop

Execute the Python script by running:

python example.py

Note: On some systems, you might need to use python3 instead of python.

All the necessary simulation artifacts and configuration files will be automatically downloaded to your computer. The COAWST simulation will then be sent to a cloud machine for execution.

Step 2: Verify the Task Status

After the simulation completes, a task summary will be displayed in your terminal.

Task status: Success

If the task status shows Success, congratulations! You've successfully run an COAWST simulation.

This simple example tested your installation on a small machine with just 4 virtual CPUs. Inductiva offers far more powerful options to supercharge your simulations.
