Don't understand that clearly. Can't I put something in the queue in the main process and read it from subprocesses ?

Is that going to provide bi-directional communication between main and subprocesses while they are running? If it does, disregard what I wrote.

Sure. You can put results in an "output" queue (which is backed by Redis) that is read by the main application.

Incidentally this is how you do a notification on your UI .
