TaoLv commented on issue #10773: specify common arch for mkldnn build, so it can be reused on all arch URL: https://github.com/apache/incubator-mxnet/pull/10773#issuecomment-386173398 I‘m afraid this will still imapct the performance of non-jit code if arch is hard coded here. Can we use a flag like `NATIVE` to control compilation during make? If the flag is True, we should compile mxnet/mkldnn according to the native machine. Otherwise, only a minimum instruction set should be supported. Anyway, the flag would be default to True. @szha Do we need to define a subset of instruction or arch which mxnet should support? I notice that there is also a discussion on dev@ about removing ancient gpu arch support from mxnet.
