Based on these initial start points, we have `Performance Tuning` to apply cost model +and evolutionary search to seek for schedules with the best performance. Candidate schedules will +be measured in the target hardware. +""" + +import tvm._ffi +from tvm.runtime import Object +from .compute_dag import ComputeDAG +from .measure import LocalBuilder, LocalRunner +from . import _ffi_api + + +@tvm._ffi.register_object("ansor.HardwareParams") +class HardwareParams(Object): + """ The parameters of target hardware, this is used to guide the search process of + SearchPolicy. + + TODO(...): This is considering to merge with the new Target: + https://discuss.tvm.ai/t/rfc-tvm-target-specification/6844 + + Parameters Review comment: We can just set values like 32 or 64 for them. The search algorithm is not sensitive to them and the default values work well for most platforms including Intel CPUs and ARM CPUs. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
