Hi Stefano,


It's probably a good idea to avoid thinking in threads until they come up as a potential solution.

Some questions:

1) What are the latency requirements? Is it okay for everything else to halt while you do that computation? What are the latency requirements for the computation? Is the data useless if you don't get it in the next n seconds?

2) What kind of machine is it running on? Are multiple cores available, and would it make sense to use them?

3) Do you require a lot of shared state with the process talking to the modem in order to make the long computation?

The easiest thing to do is probably deferToThread, but you have to be careful not to touch any state you're not supposed to touch. The second easiest thing is probably Ampoule, a process pool, or maybe just regular AMP, if you only want a regular process. Those would have the benefit that the reading process is never doing anything hard, so latency should stay predictable.
