Will it be faster to train a model on GPU rather than a CPU? how can I make it support OpenCL?

I'm trying to train some model, it takes many many hours to generate one. Actually I haven't got any of it after running scripts a whole day. Is it better to train it on a GPU?

I have a AMD R2 920, but no NVIDIA, how to make this script runs on my AMD GPU?

Thank you.

Yes, it's better to use GPU. Only NVIDIA GPU's supported, for now, but as a hack try to change this line

https://github.com/DmitryUlyanov/texture_nets/blob/master/train.lua#L66

to dtype = 'torch.ClTensor', replace all require 'cutorch' with require 'cltorch' and remove all cudnn related stuff. I do not have AMD GPU so I cannot test it and push a commit myself.

Thank you but never mind, I bought a nvidia GTX1080 yestoday, it's working good, trying to get good results.
I will try it if place the AMD GPU back.
