My team is attempting to run simulations in parallel and pass data between the simulations as they’re happening. To do this we have a docker compose yml that starts a head-node service, a service to initialize actors, and then several services to run the simulations in parallel. For some reason I can’t figure out how to share data between the simulations. Are there any good Ray /Docker tutorials out there or could someone walk me through exactly how you’d set this up? Thank you so much!
