apeforest commented on issue #16735: Use single-bit for mask in dropout operator URL: https://github.com/apache/incubator-mxnet/pull/16735#issuecomment-583539243 > so we get 15x slow down? Yes, it seems so. Not sure if it is because the extra bit-operation logic we introduced or the modification to omp parallel clause. Need more investigation. @TaoLv Can MKL VSL support bit-wise mask so we don't have to do the extra conversion which seems redundant in the MKL case.
