Hi @PHILO-HE , Thanks For the response !! I want to clarify my understanding regarding performance improvements related to AVX support. It seems AVX itself doesn’t directly bring performance gains but rather enables native libraries that leverage AVX to provide performance improvements, depending on the underlying machine's capabilities. Is this correct? Also, regarding the recommendation to set -march=native: Does this mean users need to explicitly handle this flag during their build process when setting up Gluten? Is it correct to assume that -march=native is not provided by default? Additionally, I noticed there was a PR (#7916) that initially introduced the -march=native flag but later commented it out. Could someone explain the significance of this change and why the flag was commented out? Below is the PR I’m referring to for context. https://github.com/apache/incubator-gluten/pull/7916 Thanks -- This is an automated message from the Apache Git Service.
