Why not using the GPUs to train ?

[MrLinNing]

Hello, you did a wonderful job, and why not using GPUs to train ?
Does the training procedure of GPU is slower than that of CPU?

Early experiments were done using CPU only, so we just reported those results. We tried 1 GPU on PubMed data before, it is comparable to but slightly slower than 1 CPU. But I think it is not concluded. The performance depends on the experimental environment.
