@vpirogov @samskalicky Although MKL BLAS may also have positive impact to the case demonstrated
above, I think the main gap is from different OMP runtimes. Setting `USE_BLAS=mkl` will help
to pull in iomp5. Sure I'm going to replace `cblas_sgemm` and `cblas_sgemm_batch` with the
MatMul primitive from DNNL once it's release, but I don't think that will help to fill the
gap between gomp and iomp5.
@samskalicky The code you referred will not be called in the ResNet18 case. Most of the
computation in ResNet18 should go to DNNL.
