Cluster Script Example for Third-party
======================================

.. GENERATED FROM PYTHON SOURCE LINES 8-16

In this case, we're just running a simple addition of random numbers, but
the process is exactly the same for more complicated workflows. The pre-
and post-processing is done through `model_script` and `output_script`
respectively, while the computationally intensive portion of the workflow
is launched in `cluster_script`. The example below provides a minimal framework
from which more complex cases can be constructed.
