In addition to your regular packaging,
build containers for your simulation code
This will help 'driveby downloads':
start quickly, just to play around

There's no guarantee that your users' or
clusters' machines will have a working

In addition to your regular packaging,
build containers for your simulation code
Running the code becomes a simple:

Eat it.
Rewrite in Go or Rust.
