How to evaluate a schedule during auto_schedule search

[cgao3]

The Adams2019 auto_scheduler uses beam search for searching, and a cost_model for evaluating schedules (or partial schedules) during search.

But cost model may wrongly rank schedules. I'm thus wondering how to use real hardware to evaluate schedules during the process of search? After reading the tutorial, it seems the using JIT mode we might achieve this. But I'm still not very clear how exactly this can be done, e.g., I cannot even find the input information in AutoSchedule.cpp.

Anyone knows how to do this? Is there any example might help?

Thanks very much..
