> Do they have automagic model parallelization (not data parallelization) as well? Not that I know of. Regarding claims of novelty, I don't think the Caffe maintainers are claiming that their multi-gpu update method is novel or even very good. I think it was just the easiest thing someone could think of. I think Flickr originally wrote the multi-gpu extensions and the maintainers simply accepted the pull request. If anything, I think the maintainers are more than willing to listen to people in the scientific computing community with experience. Even better if they have a pull request in hand. But otherwise, they probably won't know about better methods and won't care.
