I'm running Kera's
CuDNNLSTM) but I notice my GPU is under load. I need recurrent dropout, so I can only stick with
LSTM. Is the 'normal'
LSTM assisted by GPU? If so, how are
CuDNNLSTM different? I presume
CuDNNLSTM uses the CUDNN API (and
Similarly, is the normal
LSTM supposed to be faster on GPU or CPU?
