ZhennanQin commented on issue #11301: MKLDNN Backward op cache
URL: https://github.com/apache/incubator-mxnet/pull/11301#issuecomment-403665453
 
 
   @marcoabreu Tests are covered by 2 parts:
   1. The existing unit-tests.
   2. Train model after enabling OPCHECK by environment variable MXNET_MKLDNN_DEBUG=1. This will trigger computing for each op twice, one in mkldnn pass, the other one in default cpu pass, then compare the results. If the results are different, it would generate error message.
   
   This PR is like a refactoring work, which doesn't add any new feature or functionality, so above tests are enough.
