Hi, With the current Theano HEAD + libgpuarray, I launched two RNN-based MT systems with the old backend and the new backend and apparently the new backend is a little bit slower than the old one.
This is on CUDA 7.5, CUDNN5.1 and Tesla K40 GPU, batchsize=64: old backend: 166ms / batch new backend: 186ms / batch On a moderate 4M sample dataset, this would bring an overhead of ~20 minutes per epoch. Is this expected? If yes, why would I prefer the new backend? Thanks. -- Ozan Çağlayan Research Assistant Galatasaray University - Computer Engineering Dept. http://www.ozancaglayan.com #HayırdaHayırVar -- --- You received this message because you are subscribed to the Google Groups "theano-users" group.
