Well, updating to the last version 9.7 I get one step further, but still

Modeller's parallel support uses Python's 'pickle' module, and it's a quirk of that module that any classes you define (such as MyLoop) cannot be in the main script but must be defined in a module that you import. See examples/python/parallel-task.py for an example. So the solution is fairly straightforward - simply take the definition of the MyLoop class out of your main script and put it in a different file (say myloop.py) in the same directory as your script, then at the start of your script say "from myloop import MyLoop".
