TaoLv commented on issue #17047: Add build flag for x86 arch URL: https://github.com/apache/incubator-mxnet/pull/17047#issuecomment-564897081 @larroy We already have CUDA_ARCH, why we cannot have X86_ARCH? I don't think it's a good idea to mix up x86 arch with ARM arch into one build flag given that their have quite different options. The -march option also need be passed to MKL-DNN build, supporting both x86 and ARM in one build flag will complicate the build logic here. @leezu I read "Specifying -march=cpu-type implies -mtune=cpu-type." from https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html. Do we still need put it into the command line? @szha May I know your suggestion for the default value of this flag?
