I don't think agent are aware of each other. Which mean that you can have as many agent as you want and depending on your task usage, they will be fighting for CPU and GPU usage ...
and in general - how many agents can I open on a machine with 16 CPUs and no GPUs?

for now it seems to work just fine, as you said
