[MKLDNN] Performance on Windows - Upgrading MKLDNN submodule?

[masahi]

Hi, I tried MXNet + MKLDNN on AVX 512 capable Windows machine, but performance was terrible. I noticed that MKLDNN pulled by mxnet is quite old, and older version of MKLDNN does not enable OpenMP on Windows (omp support was added in this commit).

Do you have a plan to upgrade MKLDNN version?

Yes, we will file PR in the next week.

Great! Thanks for the quick reply.

@masahi updated, please double check if your issue is fixed :)

[masahi]

yes, I tried that PR before it was merged. Performance is good now.
