Experimental features¶
To test aggressive performance optimizations that might affect accuracy without an impact to regular users oneDNN provides experimental features.
Build-time Controls¶
To enable experimental features the library should be built with a CMake option ONEDNN_EXPERIMENTAL=ON
. Each experimental feature has to be individually selected using environment variables.

ONEDNN_EXPERIMENTAL_BNORM_STATS_ONE_PASS |
Calculate mean and variance in batch normalization(BN) in single pass ( RFC ) |
Warning
Enabling experimental features does not guarantee that the library will utilize them
Enabling experimental features might change accuracy of oneDNN primitives
