Finish hyperuqeue jobs instead of cancelling in load balancer

Hi, I also experience this, and I found it confusing as I thought my evaluations were failing! It looks like:

...
Waiting for job 21 to start.
Job 21 started.
2024-11-18T15:38:10Z INFO Job 21 canceled (1 tasks canceled, 0 tasks already finished)
Waiting for job 22 to start.

despite the evaluation being successful.

Hi @jonmaddock , this is, as it stands, expected. We don't have a cleaner way of shutting down a UM-Bridge server inside a HQ job after model evaluation.

I do however see that it's not ideal since the cancellation looks like an error. Maybe we could make servers optionally (via env. variable) accept a termination signal from client side. We discussed such a signal before, and it should not be default behaviour, but opt-in via env. variable set in the job scripts would be acceptable I think...

@annereinarz @chun9l Do you have any opinions on that?

@monabraeunig maybe an interesting next task for you after error handling?

@linusseelinger thanks for your response. I completely understand you reasoning; the behaviour was confusing for a newcomer, that's all. Perhaps I could add this current behaviour to the documentation for HPC if we don't proceed with this fix?

@jonmaddock that'd be great! Let's first see if we can come up with a clean solution regarding termination though, cancelleld jobs have already surprised other users before
