However, since the actual runtime of a DL training is significantly different from its query response time, simulators of an asynchronous HPO, e. g. multi-fidelity optimization, must wait for the actual runtime at each iteration in a na\"ive implementation; otherwise, the evaluation order during simulation does not match with the real experiment.
