ChaiBapchya opened a new issue #17915: MKLDNN 3D dilate support 
URL: https://github.com/apache/incubator-mxnet/issues/17915
 
 
   MXNet supports 3D dilate on convolution. However, it doesn't leverage MKLDNN 
library.
   
   As a result, one of our big customers faced the issue where GPU (3d conv 
dilate) ran in under 0.01 millisecond (as it leverages cuDNN library probably) 
while CPU takes ~200ms
   
   Turns out MKLDNN since earlier versions v0.10 has been supporting conv 
dilate for 3d but with certain limitations. Maybe its time to port the 
functionality to MXNet and solve the customer problem.
