Does Kaldi have any support for cuDNN primitives from NVIDIA?

[Vikrant Singh Tomar]

Seems like both Theano and Torch has support for cuDNN.  Does Kaldi already support this? If not, would it make sense to bake this into Kaldi?

No, we don't make use of cuDNN.  cuDNN seems to mostly provide routines that would be useful in convolutional networks, and since we've never had great results from using convolutional networks so far in Kaldi, and the installation procedure for cuDNN requires registration and is a hassle, it hasn't made sense to use it.

Thanks for the explanation Dan. I was not aware that cuDNN only helped in the case of CNNs. Also, in some recent work, for example this one, people have received some good results with using CNNs in speech. 

I agree that the registration process is annoying.
