Revise parallel grid search in respect to early stopping and user cancellation


We need to make sure the less common scenarios of using grid search work well. During work on I had to remove attempt to handle user (immediate) user cancellation and early stopping - that wasn't working properly.

We need to handle these cases:

  • job canceled - I think if someone cancels the job, it should propagate to all the “sub-jobs” (that is not being done)

  • early stopping - should we finish the models that are still being built - I would probably still finish them

  • better handling of out-of-time - could it be tied to job (can the job have an automatic stop time? when it appears to be canceled - hence translated to case 1?).
