Hi,

cores and ports and queues can be mapped just about any way that your application
wants. The only real restriction is that two cores cannot poll the same queue
on the same port at the same time.
You can set up your app to have each port polled by a single core, or to have
all ports polled by one core, or to have one port polled by multiple cores (using
different queues).
