 # Subgraph Optimization
 
-MKL-DNN uses blocked layout (example: nhwc with channels blocked by 16 – nChw16c) to take advantage of vector operations using AVX512.  To get best performance, we avoid reorders (example. Nchw16c to nchw) and propagate blocked layout to next primitive.

 Subgraph optimization achieves this in the following steps.
