execution_queue

is not relevent anymore

Correct

total_max_jobs

is determined by how many machine I launch the script

Actually this is the number of concurrent subprocesses that are launched on Your machine. Notice that local execution means all experiments are launched on the machine that started the HPO process.

Maybe to clarify, I was looking for something with the more classic Ask-and-Tell interface

so the way to connect "ask" in the model, is to just run an agent on that machine.
Notice that you can just create a dedicated queue and pip install the agent oon that machine, and run it in venv mode, which means very little infrastructure

Does that make sense ?
