when runs are greater than one, the execution mode defaults to multi-threaded execution when local mode is selected.

when single mode is specified, simulation execution should be single- threaded

The execution mode needs to be clear

• when using jupyter notebook, it should be multi-proccessing (related cadCAD parallelized simulations run in series #242)
• data pipelines for digital twins, should be multi-threading

note:
jupyter has control of the threads and uses tornado for multi-threading
