What to watch out for when running two instances of Hashcat at once?

[Coloradohusky]

I often run more than one simultaneously, either distributing load among GPUs, or else pausing one long-running job to run a short-running job. This is often easier than quitting and restoring.

The best way to manage this is to assign all running hashcats their own session ID with --session. You can then refer to that session by name when restoring or doing other things.

Got it; do they interact well together with the potfile or does --session make them have separate potfiles? I don't believe so, based on the wiki, so would I need to do --potfile-path for them as well(assuming that the answer to my first question is no)?
